Draganfly iv. Anyone flew it?Control?
1 Attachment(s)
Hello i was wondering dose anyone own the Draganfly iv or seen it in action in real life? I like to know how it flys. Also i was wondering how you control the Dragan flyer?
There is only two control sticks. I guess there would be one for up and down and the other left and right. But how in the world would you go forward??? I don't get it. Like any other heilcopter. The contorl thing confuse me!! I really hope to hear from someone!

RE: Draganfly iv. Anyone flew it?Control?
I fly nothing But the Draganfly!!!!!!!!! I'ts a great heli to fly, Much easier than a conventional Heli, Let me explain! First off, the Nose or front rotor is marked by having a different color blade so that you always know which is the front of the craft during flight! To hover all 4 rotors operate at the same RPM. then to go forward you push the right stick forward and that increases the REAR rotor speed to cause a slight forward tilt allowing the machine to drive forward. The Oposite for rear or backward flight! When operating your alieron function, (which is the Right stick pushed left or right) Example; to bank the draganflyer to the left you push the right stick to the left and that causes the right rotor blade to increase RPMs tilting the Draganflyer to the Left, Visa Versa for Right Banking. The Left stick, when pushed forward increases RPM on all for Rotors for Hover or increased Altitude. Take the left stick and push it to the left or right and that allows a change in Torque or RPM speed of the front & rear Rotors so that you can steer the Draganflyer like a plane does with a rudder. Anymore Question you can e-mail me [email protected] I'm Frankie.

Where is the best place purchase these machines?

And do the cameras work pretty well?

RE: Draganfly iv. Anyone flew it?Control?
How well does the dragonfly fly outdoors in windy condition ? How high can you fly it ? I'm interested in taking aerial shots of buildings. Thx

RE: Draganfly iv. Anyone flew it?Control?
I bought my DF IV right from the factory, great folks to deal with. It is a VERY stable machine, and the camera is really good quality. I've been using mine quite a lot shooting low level aerial video for a realtor friend of mine, sort of a new approach to home listings. A 10 or 15 second video of the house from 30 -50 feet altitude, a shot up and down the street and a post on the web as an mpeg file, the first house I shot for him sold within a day!

Video quality is about comparable to an analog camcorder, the only issue that I have had with the camera is that it is quite directional, so it really improves the quality if you have an assistant to "aim" the reciever at the heli while you worry about flying it.

All told, it's a bag of fun and incredibly tough. I've pounded mine into a tree in FFF, 40 ft. up and had it crash to the ground onto pavement. Total damage: a motor mount cracked, under $5. to fix. By comparison, I also fly a LMH Corona, which has a VERY good reputation for crash survivability. I just had a crash with it impacting a tree (ECS glitch, radio fell over while I was trying to correct the problem, went to full throttle and climbed out under no control), total cost to repair? In excess of $100. for broken main rotors, stripped tail rotor gears, destroyed gyro, one servo, crutch, etc.

I like both helis a great deal, but if I'm looking for a really stress free, low cost fun fly, I pick up the Draganfly every time.

Wayne, it will be nice if you could post some of the pics you took. Thx

AeroRecon 12-23-2003 11:45 AM

RE: Draganfly iv. Anyone flew it?Control?
I bought one a few weeks ago. Holiday time crunch has kept me from getting much flight time. I flew planes for years but no helo exp. QUITE a different control feeling. Still practicing hovering.

It is an amazing little thing. The video system is first rate and VERY small. Includes 4 different ways to power the video.

The videos on the DraganFly.com site are awesome. (a great time killer too!)

I just signed up here and will post other experiences as they happen.

Merry Christmas to all!

RE: Draganfly iv. Anyone flew it?Control?
I'm a general R/C neophyte and just entered the fray via obsessing over the Draganflyer IV after it showed up on the history channel. I've been waiting for this literally since the days of tethered D-cell craft and Armatron was a hot item. It's finally here, and it really isn't as cool as it seems....... IT'S BETTER. THe only thing to consider if you have a pang of desire for this craft, is how quickly can you aquire one without harming your general bill payment dates. Other than that, you only need to know that it's more fun than it even appears. 3 weeks and around 20 hours of stick time here, and went from clueless to proficient hovering, proficient maintenance, and near-proficient 90 degree perceived hovering. Not looking forward to nose-in but I will learn it. I hope to have most maneuvering mastered by 100 hours but I'm not sure if that's realistic, seems to be about right at this right, and i'm NOT naturally gifted with this stuff. Gifted probably would have it mastered completely in 30-40 hours. I have 0 affiliation with Zenon Dragan other than that I gave him $900, and i can say unbiased..... GET ONE!!!!!!!!!!!!!

Jayson ;)

Draganfly4u 01-02-2004 12:49 AM

Still thinking.
I just order a catalog of draganfly. There is a good chance i will get the draganfly. The only downside on it is the price. If i did get i would buy the 3-cell 2100Mah Li-Poly battery - ($79.95) for the longest flights! Some reason you have to call the about this and the charger.
Pretty worth is for 15 min of fligth with cam on and 20 min with it off. Not so bad. For some reason they took out the video that Zenon Dragan explain about the draganfly 3 witch was like 3min and 40 sec. I wonder why he remove that hmmm. Anyways i download the video. on another site. Too bad you can't download these draganfly videos. I have watch them so much. Just a neat flying machine!

Hey sonick thats cool you seen this craft on the history chennel! I never seen it on tv before. I will have to check in about seeing that video. I am glad you like your draganflyer. Makes me want to get one! I see you have gain skill to fly one. i think i would hover alot for video shots. It woud be neat if they made a nitro draganfly in the future! Not sure if they have the exp to make one. Well take care!!

Happy flying everyone!

RE: Draganfly iv. Anyone flew it?Control?
I fly the dragon 3 for 1 year now, its a great ship and got me into nitro heli's. Anyone mount any additional ufo lights to theres , I got some blinky lights but havnt installed them yet, what pin can i take regultor voltage from, they told me before but I forget.

Draganfly4u 02-07-2004 11:05 PM

RE: Draganfly iv. Anyone flew it?Control?
What is the diffrent between the draganfly 3 and draganfly 4? i just don't get it.

dragnaflyer 02-09-2004 07:20 PM

RE: Draganfly iv. Anyone flew it?Control?
the IV uses the li poly batteries. Flight duration is increased about 400%. I have about 60 hours on mine now, and I gotta tell you, this is the lowest stress flying there is short of the sim. The DF IV has consistently cost me next to nothing in crash parts, is very easy to maintain compared to my other, more conventional helis, and it's just a bag of fun!

AeroRecon 02-10-2004 09:22 AM

RE: Draganfly iv. Anyone flew it?Control?
Having RealFlight has helped me tremendously. I can experiment there and try things I would not while learning to fly my DFIV. The DraganFlyer is amazing. I carry it with me wherever I go now. I can just stop in a parking lot and fly whenever I want. Lots of fun.

RCairPIX 02-10-2004 11:29 AM

RE: Draganfly iv. Anyone flew it?Control?
Hello to everyone on the board.

I am in the process working my butt off to get one of the DraganFlyer machines.
As a kid, there was a field behind my house that a group of guys bought and converted into
a cool airport for RC planes, jets and helicopters. Since those days of watching the little planes zip
around, I have always wanted one.

I am now 31 years old and recently a practical application brought
the idea of RC airplanes back to me. I work for a Tree Service, and right now my boss is putting in
bids on land clearing jobs. I was thinking it would be really cool if he could have some areal photos of the
property he is trying to check out. I then realized that the cost would be high to hire someone to fly over
and take pictures....but if I could buy a little RC plane....get a wireless cam hooked to it....CHEAP areal photo!

So..I started to look on the web for cameras and planes. I looked at all kinds of planes, helicopters and even blimps and
then WHAM - i ran into this incredible Draganflyer. I MUST HAVE ONE.

It seems to be the perfect thing for what I want to do. I could fly the machine up over sections of the land and get good pictures.

I really want the Draganflyer Xpro or maybe even something custom built to lift 5lbs. I know that is going to cost some big bucks so until I can get the funding to get the big machine I am going to order the smaller DraganFly IV with cam to learn with. I should still be able to get some good pictures with it.

This is a great forum - I would like to share ideas and experiences with you guys when I get my machine - until then I will read your posts and dream of getting my Draganfly. I would love to see pictures from you guys and would be willing to use my web development skills to start a site specially for people who fly DraganFlys. My main interest is areal photo with RC vehicles, but would love to talk about anything. Here is my email [email protected] - contact me anytime.

RCairPIX 02-10-2004 12:11 PM

RE: Draganfly iv. Anyone flew it?Control?
One more thing -

Has anyone heard anything about any of the bigger custom machines that can be built? How about a machine big enough to lift a 200lb cargo? Has it been built?

Kactusking 02-10-2004 01:33 PM

RE: Draganfly iv. Anyone flew it?Control?
It is good to see some other Draganflyer folks.)

I am new to this board, but not new to RC flying. A long term fascination of mine has been aerial photography, and I have tried various methods of achieving this. I started out a number of years ago with a large parafoil kite, a stratoscoop 4 that is made by Greens of Burnley. This kite lifts between 20 and 40 pounds, depending on the strength of the wind. I attached my father's video camera to it, and after some nice footage, the camera came loose and crashed to the ground. Since then I experimented with other kites, but the limited maneuverability, combined with extensive launching requirements (i.e. large field, the right wind, etc.) led to more frustration than anything else. In addition, kites tend to become more unstable and more likely to crash the higher they fly. The next phase involved purchase of a very well built RC paraglider from Dave Garber. This machine has a Zenoah 62 engine, and a 12 foot foill attached to the back. It came with a professional aluminum camera mount, and easily accommodated a digital video camcorder. Once again, initial success and I did get some fantastic video of my neighborhood. This I thought was the perfect vehicle, as it required very little runway, was easy to control, and so well built I believe almost indestructable (it is entirely out of steel and aluminum). However one morning, with the camera on it, I lost control and the throttle opened up autonomously. I watched it go higher and higher, then drift with the wind toward the south. To make a long story short, it ended up on a naval base about 10 miles away, crashing into the fuel depot, having glided in right over the runways for the F-14s. I endured several meetings with the FBI over this incident, as they wanted to make sure I was who I said I was, and not some terrorist. They did eventually give it back to me, sans videotape. I have been too scared now to even fly it again, and after thinking about it quite a bit, it is so heavy that it certainly could do some damage to people or property if I lost control again and it crashed somewhere. Enter the current phase, the Draganflyer.
I got this from my wife as a request for my Christmas gift, and I have been most pleased so far. I am still on a steep learning curve, as I have only become proficient in hovering (which is good because replacing rotors and capacitors was becoming expensive and time consuming, respectively). Perhaps I am delusioned again in thinking that this is finally the ultimate flying platform for videography. Like the previous poster, I am mainly interested in the X-Pro, but I think it is wise to become proficient on a much cheaper model first. I would love to see some photos posted or even aerial videos. I did not buy the camera, as I was dubious about this craft's capabilities in the beginning. However I am starting to feel confident this will become a very long term endeavor and not end in disaster like so many other things along this avenue that I have tried.

RE: Draganfly iv. Anyone flew it?Control?
Just got my Draganflyer III last week from an auction right here on RC Universe.
Brand new in box for only $550 USD delivered with two 10 cell batteries, to Toronto Canada.
I have some RC experience with planes and very limited with heli's.
When I first received the machine it only took about 40 minutes to assemble. The video is about 1/2 hr. long. Not great quality video. Need a good VCR to track the lousy repro. The first half is instructional assembly. The second half is a brief lesson on controlling the Draganflyer on an "X" on the ground (makes sense). Then some great video of Zenon (same as mpg's posted) but clearer and longer, giving a brief lesson and a demo of his and the Draganflyers skills. Some great outdoor videos too!

After about 10 charges of the battery (ten attempted flights) and cracking-up two blades off my basement walls, I'm now getting the hang of it.
It seems the key is to "jump" it off the ground about 2 feet (half throttle). You will then have less ground effect and easier control.
But be aware that you must gain an element of experience controlling this thing or you will most certainly plant it into a tree or ground .

My back strut pylon sheared-off (lock-nut and all) in a panic landing. Had to glue it down. (seems to be holding nicely). Part of the circuit board keeps popping off 2 of the strut mounts in heavy landings. Maybe this is designed to give way to avoid damage to board??

Made my own tether-cord. Used plain wire (heavier gage) and soldered on some connectors. Needs a bit of ballast so I use the weight of a 9volt battery velcroed in.
I get about 10-15 minutes with the tether. I highly recommend this.

Take your time and buy lot's of blades.

[&:]Does anyone know where I can get (or the name of) the battery connectors supplied with the Draganflyer? Hobby shops here say it's unusual...?
[8D]Anyone vaccuform their own blades? Charge 5 bucks each and you're in business!

HMM i was wondering about the draganfly cam? How long can you record for and how you get what you record on to the vhs tape? It boggles my mind. These are the only thing i like to know about the cam! Lucky thing them blades are foam so they can just snap and not hurt someone! I would love to fly draganfly like in a mall! be so cool! If you have notice they took out a video of the draganflyinfo.mov for some reason. Not sure why. The draganfly info video told alot about the draganfly. Which i happen to have saved on my computer.
I wonder if anyone got the draganfly x-pro. That thing cost way too much!! you can get 5 draganfly iv for that price. Well here some pictures of draganfly iv!

CanadaKen 02-10-2004 04:38 PM

RE: Draganfly iv. Anyone flew it?Control?
Camera is quite simple really. First the camera (mini) plugs into the DF circuit board. Is powered by your onboard battery. Very little power to drive the cam. It gives off a frequency (transmits a signal) to the supplied receiver. This receiver has two jack plugs on it. Audio and video. They are universal and can be plugged into any TV or VCR. Turn on the monitor (TV) and "viola", your picture should be clear. Press record and away you go! Some interference from electrical motors at times. Can record as long as you have power and tape.


You may be allowed to fly in a mall if your father owns it and it's at 3 in the morning?

AeroRecon 02-10-2004 06:56 PM

RE: Draganfly iv. Anyone flew it?Control?

This will be my next purchase. The video receiver plugs into eyeglasses that have a single lens video monitor just to the edge of sight. I guess you just look to it and the focal point stays the same so you can be watching the flyer and also see what its looking at! Awesome. RealFlight offers the 'out the front window' cam-type thing...no way you could only fly from the video but it would sure help to orient the craft once it gets away from you.

Anyone have experience with the Eyetop system??


dragnaflyer 02-11-2004 08:59 PM

RE: Draganfly iv. Anyone flew it?Control?
I have looked at the eyetop and I'm not sure.........I have a set of Olympus video glasses, and if anyone is thinking (like I was) that it would be great to fly with the glasses only; THINK AGAIN! You lose a HUGE amount of spatial reference and positional awareness (not to mention getting rather nauseated almost immediately) trying to fly with the glasses alone.

I'm pretty proficient with the DF (close to 100 hours) and haven't crashed it in a LONG time, but every time I try to fly with the glasses, it's on the ground (sometimes in more than one piece) almost immediately.

They are useful for shooting video. My camera person (SWMBO, A.K.A. my wife:D) wears them while I'm flying to monitor what I'm shooting. She finds it a lot easier to keep track of what is being recorded and direct me into a new position or attitude with the glasses than with the viewfinder on the video camera.

Although since getting the DF I've got the helicopter bug BAD (4 other conventional helis and counting) I still find that the DF is the most trouble free fun of any of them, not to mention the toughest by far! I have crashed it many times, several with considerable speed and altitude, none with damage so severe that it wasn't back in the air in under an hour.

As for the Pro, I saw it fly at the factory in Saskatoon........IT IS AWESOME! A lot of $, yes, but the day I saw it fly the wind was blowing about 20kmh and gusty, and it handled it with virtually no problem. It is a lot bigger, heavier and has a much higher ifting capacity, and the engineering is really something to see. I see it as all being relative; I know a couple of guys who are flying scale helicopters that they have well over $5000. invested in. They are beautiful to watch, and I'd love to own one.....I'd love to own a Pro too. If you can justify the purchase price of either, then they're well worth the money.

(no, I don't work for Draganfly Innovations, but I am darn sure impressed with their products!)

Could someone tell me what the specs are for the motor capacitors on a DF IV? I'd like to get some right away.

RE: Draganfly iv. Anyone flew it?Control?
I guess I'll answer my own question - 0.001 microfarad ceramic-disc caps.

BTW, a good place to get 6-32 x 3/8 round head (or pan head) machine
screws is www.mcmaster.com - $4.95 plus shipping for 100.

Does anyone know the motor specs?

Hello i was wondering could you use 7.4V 4200mAh Li-Poly Battery for the draganfly iv? It's not really for it tho. For the predator really.

AeroRecon 02-17-2004 06:02 AM

RE: Draganfly iv. Anyone flew it?Control?
Saw the Predator last night for the frst time. Looks awesome! Wonder what the GPS control system will add to the price?
Placed my order for the Eyetop glasses yesterday. I will let everyone know how they work. Ordered the clear lenses too.
I had DFI send me a handful of extra screws when I popped my two spares in the first half hour of flight. I think an extra set of rotors and screws should be included in a starter kit.

Norfolk? I'm in Fredericksburg. Maybe we should get together and fly sometimes. I have a DFIV on 44. What channel are you on?

Captain Pugwash 02-17-2004 06:07 PM

RE: Draganfly iv. Anyone flew it?Control?
Hey there fellow DF'ers
Got my DF lV delivered yesterday but the camera was missing, DFI had put a letter in the package saying they were on back order and would be sent out 3-7 days time, but thats more like 2 to 3 weeks for me coz im in the UK :( .
Got the DF set up in about 1 1/2 hours , attached the tether cord and started my learning curve. after about an hour of hopping around the room i got it into a steady hover and kept on hovering for about 30 mins i only stopped coz my brain was so blitzed and i coudnt concentrate any longer. I left it for about an hour and went and had a cup of tea and some Hob Knobs then started to hover it again ,that was until it keeled over to the right and dropped like a ton of bricks. On inspection i found that one of the little brass cogs on the motor's had slipped down the shaft and wasnt connecting with the main prop cog,it now spins freely on the shaft and comes of completely from the motor [:o] HELP!!!!!! how the hell do i get it to stay on and grip the motor shaft????????

Was gonna try using superglue but thought against it coz i dont think it would take the forces involved, :eek: i am now thinking of trying some kind of metal cement to see if that will hold , but surely this shouldnt be happening wot if all the brass cogs fail on the shafts ??? God help me if im up high with the DF coz it will just fall out of the sky, Has any one else on here had this this problem happen to them???? [&:] ive only had it 2 days and about an hour of stick time and im grounded already coz of a stoopid little bloody brass cog[sm=thumbdown.gif]

Any help would be very much appreciated chaps coz as you might understand Sasktoon Canada isnt just round the corner from Liverpool UK [sm=tired.gif]

Thanks a lot and watch out for those LITTLE BRASS BLOODY COGS...............

AeroRecon 02-17-2004 06:20 PM

RE: Draganfly iv. Anyone flew it?Control?
Bummer!!! Did you call DFI about this?? That is very odd. I bet they would FedEx one to you pretty quick. They are a GREAT bunch to work with.

Make sure you don't fly much more than 15-20 minutes at a time, though. The motors do heat up pretty quickly. That MAY have had something to do with it but hard to say.

I got the tether too but have just done battery flying. Did you add the battery as ballast while using the tether? This was recommended to me by DFI.

I love mine! Having a great time with it.

Good luck!!

Captain Pugwash 02-17-2004 07:02 PM

RE: Draganfly iv. Anyone flew it?Control?
hi there Aero [8D]

!! UPDATE !! Just noticed another brass cog has dropped down the shaft on ANOTHER motor but its just about connecting with the main cog i can move it up and down the shaft with my fingers so thats another one gone :( :( This is Bloody STOOPID !!!!!

I did actually phone DFI yesterday but not about the cogs, when i had put it together i noticed that my DF didnt have the plastic cup protectors on the bottom of the motors like i had seen all the others have on the DFI website!!
The chap i spoke too explained they dont use them any more because the motors tend to get too hot with them on, i explained that all the soldered wires and the resistor are showing and would be prone to being "hit hard" on the ground, but he said thats the way they are now so i took his word for it.

How The Hell do i get these cogs to grip to the shaft????? So i guess that means the other 2 cogs are eventually gonna fail on me.

AeroRecon 02-17-2004 07:11 PM

RE: Draganfly iv. Anyone flew it?Control?
I questioned that too. But I found these thingys at a hardware store. ITs a major brand over here but not sure of the name. They make a whole line of these pad things for easily moving furniture and stuff around. Hard pads that have rubber on one side and are hard and slick on the other. The new thing I found is for the bottom of chair stools. About an inch in diameter and are soft, cupped rubber on the non-hard side. They gripped the motor bottom fine and still allowed air to move around becuase its not a perfect fit. but they grip well and are slippy on the bottom. The can come off but only after a bang up. Then you just slip it back on. I did this after a few bang ups on asphalt ate off the capacitors on the bottom. DFI sent a strip of new caps to solder in place. Poor design having the bottoms exposed and a REAL bummer that your motors are failing. They will make good with you on that I am sure.

durf786 02-17-2004 10:00 PM

RE: Draganfly iv. Anyone flew it?Control?
I was wrong about the size of the motor capacitors. I got out a magnifying glass and managed to read 104K on one of the caps. That would be 104K picofarads, or 0.1 microfarads. On the plus side, they're easy to get.


Captain Pugwash 02-18-2004 05:48 PM

RE: Draganfly iv. Anyone flew it?Control?
Got some Loctite 642 bearing retainer today and fixed the 2 cogs that were loose ,,, seems to have fixed the problem they seem to be fastend on hard ,, good stuff this Loctite.... just wondering if or when the other 2 cogs might fail but so far they seem solid..
Im wondering whether i just got unlucky and got 2 motors that were put together badly ,would just be my luck that[&:]

Got back to my hovering around the front room and everything seems fine and dandy.. In Answer to your question Aero, no i dont use the battery as a Ballast when flying with the tether cord it seems to hover around just fine without.

AeroRecon 02-18-2004 07:26 PM

RE: Draganfly iv. Anyone flew it?Control?
Just got my Eyetop video glasses in. Pretty slick. The lenses are not as perfect-clear as I would have liked but I think they will be useable. Will try them outdoors tomorrow. I think they will take some getting used to, though. Very clear picture using the Eyecam from DFI. I ordered a set of clear lenses but they are coming from a different place so will take a few more days to arrive. Don't think that control of the DF will be possible but all I really want to accomplish using them is for aiming the camera in generally the right direction. Should help with orientation if it gets too far away. We'll see.

RE: Draganfly iv. Anyone flew it?Control?
I just received my Draganflyer IV after a long wait! I`m afraid of damaging it and wondered if any of the "simulator Heli`s" that come with Real Flight are similar to the Draganflyer? I know I should just go out and practice but I`m on crutches for the next few weeks and the closest I can come to practicing right now is through Real Flight. This is my first post at this Great Site! Thanks!

Captain Pugwash 02-19-2004 07:10 PM

RE: Draganfly iv. Anyone flew it?Control?
Hey there nike...

When you say your afraid of damaging it do you mean your afraid to fly it full stop????

Did you get the tether cord?? you definatly need this,,, no need to mess about keep charging the batterys for some stick time....

Ive only had mine 4 days now and i can hover in one spot no problem now, for as long as i want ive even started to do 90 degree hovering , its Bloody hard!!!![>:] in total ive snapped a total of 1 blade's and chipped quite a few more but i just get my Dremmel out and sand em down a little and they seem fine ,,

Believe me Nike these little DF'S are a LOT tougher than they seem dont be scared to get it up hovering even if you do crash chances are there wont be a thing wrong with it , you may chip your blades up but like i said you can sand em down a little and they still work fine.
After every bump ive had so far i found all i had to do was straighten up the motors and off i go again.

By the way as a matter of interest just keep an eye on the brass cogs on the motors ,, ive had 2 of mine come loose and fail i would be interested to see if any one elses does the same .. ive used Loctite 645 bearing retainer on the 2 failed ones and it seems to have done the job.

Did you order the camera with yours?? I did but i had a letter in my parcel saying they were on back order and wouldnt be shipping till 5-7 days time.. Coz im in the UK that will proberbly be 2 weeks for me...#

Ive had about 5 hours stick time so far (4 hours on the tether and 1 hour on the Li Po's) and im really enjoying it , All the Heli chaps at my flying club are amazed at how quick ive been to be able to hover it so skillfully, some of the chaps there have had thier Helis for months and they still cant hold a hover for more than 5 seconds at a time.. im gonna ask one of them to let me try thier raptors to see if what i have learned on my DF will transfer straight away to the real Helis...:eek:

Any ways Have Fun,,, after all its what its all about!!!!

Hey Captain...
Thanks for the encouragement. Yes, I guess I am afraid to "throttle up" too much. I have a very limited space to practice in and outside isn`t an option for me quite yet. So far, I`ve only practiced for about an hour total and haven`t gone past 6" in height. I have chipped up a few blades but they seem to be holding OK. I read somewhere that hovering and control improve once your up over 2 feet. Is that your experience with this? Yes, I bought the tether cord and the camera and I`m really excited about trying to get this thing to hover in one spot for more than a few seconds! I would appreciate any other helpful hints for a total rookie! Thanks again for your response. Nike

Hi Nike. I have to agree with Pug, fun's the thing! Send in an order now for a half-dozen sets of rotors and don't worry about it.

If you've only practiced for an hour, I'd say 6' is a tad high. It's true that hovering is a bit easier when you get out of the ground effect, but with a few more hours of practice you'll be able to keep it in one place a few inches up. That will give you more confidence when you start rotating it. If you're going to crash, crashing from a few inches is, in my opinion, better than crashing from 6'.

Okay, here's my tip, learned from painful experience. PAY ATTENTION TO THE BATTERY LIGHTS ON YOUR TRANSMITTER! Sorry about the caps, but my experience was traumatic. I was out in my garage practicing hovering. It was hover a few seconds, chip a rotor, hover, chip, etc. I was practicing 10 minutes at a time, then taking an hour off. As time went on I got better and was getting excited about it. I cut the cord and was hovering on the battery - very exciting! Then it happened. During a hover all of the motors went to full throttle and my copter crashed full speed against the wall of my garage. Believe me, it was not a pretty sight! The batteries in my transmitter had gone low and lost control of the copter. On the plus side, the DF IV is a sturdy craft, and I was running again in an hour. (I had to order a few rotors and other parts after that, I admit.)

Have fun!

Hi Durf,
Actually, it was 6 inches, not feet. I just wish the snow would all dissapear so I can take my practice sessions to the yard. You mention buying lots of blades. I have a few chipped blades already and was considering using clear strapping tape to "reconstruct " the leading edge. Anyone have any advise about this? Also, do relatively small chips make a lot of difference in craft stability? Thanks again for your reply.

I use regular thin scotch tape for my rotors. After I knicked a few tips I sculpted the tape to a similar shape. Works so well I cover the leading edge of all my rotors now with a strip of tape. One thing to watch for is balance. I bought a small prop balancer...the kind you hold between your fingers...and that works well. I lightly sand all my rotors to smooth edges, add a strip of tape to the leading edge and tips and then balance them. Add small pieces of tape to achieve balance as opposed to sanding off the blade. And if you have knicks in the blades now with small sections missing, just 'fill-in' the missing part with tape and keep flying!! I have even had great luck while practicing, using blades that have been taped back together after being broken. I lift gently to make sure they won't warp funny at the break but it has really helped. I am saving my new blades for unfixable breakages or when I get better.

Did you ask about RealFlight? If you don't have it, GET IT!!! That is an amazing tool to learn with. I take chances using it that I would never do with the DF. It has helped me a lot! You set the flying field to the house that is included. Then you add a few new view windows. One for sort of a relative attitude of the bird in relation to you. Move it to the lower corner of the screen. Set another view looking out the front window. Then use the main screen view as a normal, ground based view. Position yourself (F8) a few feet away and then save the whole thing. I use the trainer helos mostly and the electrics but the bigger birds are fun to mess around with.

The 'camera' view out the front window is sweet. I have found that I can keep the choppers flying around the house and control it so that the house stays in the front view. Then jsut go round and round. Cool. So, I had to go and buy a set of Eyetop.net video glasses to try and reproduce the same setup. Just got them in and am still scared to take the DF up high enough to really try it out. Should work well to reproduce the same setup as in the RF sim.

Oh well...Back to work!!! (whip, whip) Later....

RE: RE: Draganfly iv. Anyone flew it?Control?
I've got quite a lot of time on my DF IV, and I found early on that there is a product that works amazingly well for repairing rotor chips. It's called "plastex", it's a 2 part molding compound, one dry one wet, that includes a small piece of mold making material. you heat up the molding putty and press it against an undamaged edge of a rotor (make sure if you have chipped a leading edge, copy a leading edge, not a trailing edge!)

Once you've made a master, align it with the damaged area, and apply the plastex per directions. (a small drop or two of the liquid into a mound of the dry, pick up the resulting ball of material, place it in the area you're repairing, then flood in more of the liquid until it flows into the gap) Then, just hold it in place for a couple of minutes until it sets up enough to remove the mold, then let it cure for an hour or so.

Once cured, it sands beautifully, and it's density is very close to that of the rotor styrene. I have never had to rebalance a rotor repaired this way, nor have I ever had a failure in one that's been repaired this way. It's really good stuff!

WARNING: (two actually) this stuff stinks! make sure you have good ventilation away from open flame or sparks, cause it burns too. Don't try to use this as a repair medium on a conventional helicopter rotor. No I haven't tried it, nor will I, EVER. I have no intention of have a meter wide horizontal circular saw fail at 1800 RPM because I was too cheap to replace a $40. set of rotors that were damaged. The DF rotors are light enough, and the disc loading even lighter, that I don't have too much concern about the repair of these little guys.

If you're interested in trying it, the company website is www.plastex.net. This stuff is not cheap, but I have used my small kit many, many times ( you only use a very small amount of the stuff for each repair) and still have lots left
