CaptainRandy -> RE: Does anybody fly Accipiter Badius in here? (7/12/2004 4:09 AM)

Has anyone used Li-Poly batteries in the Accipiter Badius Slope Diver?
Which ones fit the small area allowed for battery pack? Brand size etc.
How long a flight times?
Thanks, Capt. Randy[:D]



Pilot Ray -> RE: Does anybody fly Accipiter Badius in here? (7/12/2004 7:10 AM)

Hi CaptainRandy, Thats a very interesting and well done modification you did on your Accipiter Badius. Although I have been mainly keeping track of the Accipiter Badius part of the RC forum here for a few months, I figured I would now try and see if my posting works. I have the Accipiter Badius and I will do some posting here of what works for my plane soon. I to was wondering about the Li-Poly batteries and how much running time could be gained by using them.

Ray



CaptainRandy -> RE: Does anybody fly Accipiter Badius in here? (7/12/2004 4:17 PM)

Hi Ray, Welcome to "Badius World". Your post worked just fine. If I don't get any input in a couple of days on the Li-Po's, I will just get my but down to the local hoby shop and see what fits.
I love to fly my badius, but I need longer flights. They are not too bad, 12-15 and possibly longer when I can catch some thermals, but with that flat wing and ailerons it's not as good.
Anyway, welcome and keep flying.
Capt. Randy



lduford -> RE: Does anybody fly Accipiter Badius in here? (7/12/2004 5:24 PM)

i am also interested im li po batteries if i find anything out i will post i love my ab so much i just bought another one on e-bay[:D]



chickenlips -> RE: Does anybody fly Accipiter Badius in here? (7/12/2004 8:16 PM)

Could some of you that have your Badius trimed out nice please post some
info/measurements on your C.G.? Tnx



rszanti -> RE: Does anybody fly Accipiter Badius in here? (7/12/2004 9:33 PM)

Hey CaptainRandy

Neat Mod ! I did notice that with the linkage setup you have, you should get a lot more "down" aileron than "up". Since most planes tend to lose altitude in a turn, this might also contributes to that - have you noticed the need for any more "up" elevator when making a turn ? Curiousity on my part since I thought about doing ailerons too.

And I second chickenlips request - whats a good location for the CG ?

Richard



CaptainRandy -> RE: Does anybody fly Accipiter Badius in here? (7/13/2004 1:58 AM)

Hey ChickenLips,
I have mine balanced out to 8 7/8" back from the tip of the nose cone and it seems to fly nice. I do add a tad of down trim, so I guess it's not perfect. I am happy with it.
Capt. Randy



CaptainRandy -> RE: Does anybody fly Accipiter Badius in here? (7/13/2004 2:10 AM)

Hi Richard, I posted my CG as 8 7/8" back from the nose cone tip.
As for my ailerons, they are not perfect bay any means, but they did work as a first attempt at trying this. You are correct, there is a LOT more down than up, in fact I was wondering about that before I tried it, but it worked. I was wondering how it would be with one aileron being not equal to the other. It was my installation and not the recommended way of doing things. In a perfect install each aileron would move the same amount up as the other one would be down, if you know what I mean.

I didn't find that I need any more elevator to maintain altitude than I did with the poly wing. In fact she banks pretty well with the poly wing. I just wanted to see what would happen and I wanted to try to flip her upside down and fly inverted for a while. She did that pretty well, but I couldn't seem to get a 4 point roll out of her, but then again I am a newbie also.

I am sure there is a better way to install ailerons, BUT I just wanted a fast and simple way to try it. I didn't want to go through all the torsion rods etc. I don't think the wing really lends itself to all that work.

I think it was worth the effort that I put into it and it was fun giving it a try.

I am going to my club meeting tonight and they are going to have a speaker on electrics, so maybe I can absorb some info and relay to all you guys what I hear.

Please post all your neat stuff on the AB, so we can all learn.

Capt. Randy



CaptainRandy -> RE: Does anybody fly Accipiter Badius in here? (7/13/2004 2:19 AM)

Here's a funny story,

I went to the field with my Sig Bristol Scout and my Badius. I first launched my Bristol scout and while flying around low and slow I noticed that the motor was kinda cutting out. I kept on flying around until the battery ran out, then I launched my Badius...... Same thing, the motor was cutting out. I was saying to myself what are the odds of this trouble with both planes. I had my Badius up pretty high at times and not until I was back on the ground that I noticed..... Hey STUPID, you antenna is all they way down on the transmitter. WOW! that was close to a fly away.
[:D]Capt. Randy



Pilot Ray -> RE: Does anybody fly Accipiter Badius in here? (7/13/2004 9:21 AM)

CaptainRandy, You reminded me about something in your last post when you mentioned about forgetting to put up your antenna. I noticed on just my second attempt to fly my plane awhile back, That in this instance, (I was much too close to my house) when I was almost 25' high during a bad take off and the plane ended up heading right and to the back side of my house out of sight and then went silent. I was amazed that it had landed on the roof, when I thought it should of easily missed the house and crashed further away from the house. This got me a thinking that apparently when ever the plane goes out of sight behind a rather solid object, it must have a fail safe automatic motor cutoff to prevent plane from flying to far off or maybe is just the nature of the Accipiter Badius's radio frequency. Either way I was happy it stopped the motor. Then this got me a thinking again, I figured that if the motor stops running when it is blocked by a solid object, then maybe it would stop running just by hitting the on/off switch on the transmitter. Well I was again amazed that switching the on /off switch on transmitter to off will work for instantly shutting the motor off. I now keep this in mind as a faster way to quick kill the motor if in an emergency dangerous situation. I now wonder if this could also maybe be away for a last resort emergency stop to prevent a fly away plane. I guess I should note here to that turning off the transmitter does also shut off rudder and elevator and this method should only be used to crash stop the plane. I was wondering if everyone else's Accipiter Badius planes can do this or is this just how all RC planes function.

Thanks, Ray



CaptainRandy -> RE: Does anybody fly Accipiter Badius in here? (7/13/2004 5:00 PM)

Ray, I don't think your motor stopped as a result of flying behind your house. The transmitter does not need to see your plane or vise versa in order to communicate. What does happen with most all speed controls, is when battery power falls to a specified level it will cut out the motor and only supply power to the receiver. This happens to allow the pilot to control the planes rudder, elevator etc. in order to bring her down dead stick. I am not sure in the original equipment (speed control) that the badius came with has this feature as I removed mine after the first flight and installed a Great Panes motor speed control. My speed control was damaged or something after the first flight and would not restart after a throttle back. I would have to push the button to get it going again, and I couldn't reach the button when it was over 7 feet high. The newer speed controls are much smoother and much more reliable( no buttons to push). I also, as I may have mentioned, replaced the radio equipment in my Badius with 72 mgz Futaba gear. I found a guy on ebay that sells Badius Planes and parts pretty cheap, but he doesn't stock Poly wings. I have email him and he said that he is going to look into getting some.
Stay off your roof, they are much too difficult to land on.
P.S. I would not use the on/off switch to kill the plane. Use the motor slide switch on the back of the transmitter, this way you still have other controls to steer clear of people, roofs etc.
Many times you will be really high riding thermals at hundreds of feet and your battery will not have enough power to power the battery, but will have power for the control surfaces.

CaptainRandy -> RE: Does anybody fly Accipiter Badius in here? (7/15/2004 4:43 PM)

Hi Ray,
Just received your email and I will be answering it right away, but first I had to go to the RC Universe forum to make sure I got the picture posting procedure correct. I think it is basically the same between RCU and RC Groups forum except the size limit of the photo file, and one allows 4 pics and the other 5 pics. Anyway right here where you type your message, look down to the lower left and you will see Upload Images Just click on that and browse through your picture files until you see what you want to upload. They give the file sizes right there.
Wait until it says file uploaded sucessfully and you will se a box open and it will have on the left the file with the little paperclip showing attachment.
If you click preview, you can then click on the paperclip and see the photo that you uploaded.
The box on the bottom shows Attachment-----Delete---- Upload more files----Add signature
I hope thatwas clear as mud, lol.
I usually check the box that says Notify me me someone replies. Give it a try. Capt. Randy



afineman -> RE: Does anybody fly Accipiter Badius in here? (7/16/2004 4:01 AM)

I just got my AB today, I was tuning it up for it's first flight tomm.
My question is, every one talks about CG but, is the CG along the fuse or at the wing tips.
I have front 1/3 at wing tips and 1/2 at fuse, all the posts I have read said CG should be ( tips or fuse) 1/3 SSOO am I good or bad.

Thanks in advance for helping the new guy


Brent



CaptainRandy -> RE: Does anybody fly Accipiter Badius in here? (7/16/2004 4:37 AM)

Brent, Actually where the wing meets the fuse. I have a spot on my Badius marked with a sharpie on the bottom of the fuse that is 8 7/8" back from the tip of the nose cone. I can almost balance the plane on an pencil eraser at that point although it is difficult. Better to just hold the plane under the wing close to that point and it should balance. Balancing it from a single point under the fuse as I have just checks balance from front to back and side to side, but not nessesary. Hope this helps. By the way, my plane flys perfectly. I am attaching a photo of my balance point (CG) Good luck with you flight and let us all know how it goes.
Capt. Randy



afineman -> RE: Does anybody fly Accipiter Badius in here? (7/16/2004 4:49 AM)

are you using the std. wings or the poly wings, do you have both, and is the cg in the same location.

Thanks


Brent
ps OOPPSS I see you are using std wings, your picture was not there when I first responded

Thanks.



CaptainRandy -> RE: Does anybody fly Accipiter Badius in here? (7/16/2004 5:13 AM)

Brent, I have both, the one you see in the pic is of my mod to the flat wing. I added ailerons. You can see all the details in previous posts.
She flys better or eaiser with the poly wing. Agian see previous posts.
Capt. Randy



Rubens Sayegh -> RE: Does anybody fly Accipiter Badius in here? (7/16/2004 6:20 PM)

In fact, as the planes are "supported" by the wings, the CG should be located somewhere along the wings AND the fuselage. That means, for most cases, under the part where these two elements meet. Some planes, witth different designs could have the CG located elsewhere, but in "traditional design" planes, prevails the first rule.

What is a very good idea is, besides defining the CG point, is to check if the "commanding weight" is also well defined. One thing is to see if the plane´s CG is well positioned, another is to see if, when flying, the CG will "inform" the plane it is "in the right direction". I´ll try to explain...

After defining the planes CG, tie a piece of rope (about 5 feet) around the plane, in such a manner that you can "hang" it. It should be positioned in a perfect horizontal plane. Then, try to rotate the rope, just like you were flying a kite. The plane should "fly" with the nose pointing forward. As it is also a soarer, it is important to determine if, while flying with the engine off, it won´t try to move the tail to the front of the direction of flying. It is quite common to determine the correct CG, but the plane still misbehave when soaring...

Hope this helps... : ]

afineman -> RE: Does anybody fly Accipiter Badius in here? (7/17/2004 5:23 AM)

[:D] well it's first flight was at 6:30 AM this morning, hand tossed about a dozen times to do some fine tuning, then about 4 flight with power for 10-15 sec, then for the last flight turned it on and let it go. I lawn darted a few times ( now that I own an AB I know what everyone is talking about), and was unsure if the eratic flight was me or the plane. The day was windy so I spent it checking everything, the rudder was not screwed in all the way ( OOPPSS my bad), became anal about CG wing angle, wing spacing, etc.
wind died at 7:15 tonight so I went flying. taped the ground only twice and spent the rest of the charge getting up there and then dead sticking it in.
next charge flew great ( I started to calm down)1/4 throt. 100 feet up, crused the entire charge. The field I fly in is a big L shaped field so I was doing left and right turns, I did notice, WOW do those wings flex and I was wondering what everyone does about that. I also notice at 1/4 power this thing is really quiet.

well that is my first day with the AB, Sat is going to be no wind ( so they say ) I can forsee a day of flying.

Have fin all

Brent



CaptainRandy -> RE: Does anybody fly Accipiter Badius in here? (7/17/2004 3:46 PM)

Brent, Congrats on your firtst flights. The more you fly it the eaiser it will become. Soon you will be saying " What's all the hoopla about, this thing flys beautiful". I have only flown mine about twenty times, so I am no pro either. I practice practice practice on my thermaling and landing at my feet (almost had to duck a few times) You will know when it feels good as far as balance etc. I am going back to my Poly wing, I like it better than the aileron flat wing. It soars better and longer with the poly. Keep up the good work.
Capt. Randy[8D]



afineman -> RE: Does anybody fly Accipiter Badius in here? (7/18/2004 3:12 AM)

HOWDY ALL

Today I went flying, I got a total of 90 min of in air time (11 flights) and no crashes, the first 2 flights I did notice though my palms were swetty and I fealt like I drank 10 cups of java. the afternoon got windy but I kept flying (cocky I guess). I found the thermals ( same thermals I lost my 1st plane in 2 weeks ago), I have a total of 15 flights and still on the same wings, tail, prop, etc. I am using the flat wings that were taped up on leading, trailing edges as well as a strip on the underside.

I won't say I have mastered this, BUT I am feeling much better about flying this.

because this was not my first plane ( started with this http://www.raidentech.com/burerarecoai.html ) and because my first plane didn't have an elevator, I lost it in the thermals. with the learning curve I went through ( first plane and sim time) I personally would not recoment the AB as a first plane.

Just a little back ground.

I have been trying this hobby for over 30 years ( my brother too) with NO luck. my brother and I have spent thousands of dollars and hundreds of hours building an the crashing RC planes.
We came across a pair of cheap electric foam planes and bought them ( figuring the flight expirence will end like all the others), well we both were able to fly, we had both realized a 30 year old fantisy ( and we found out what our varing problems were with trying to fly ). I got about 2.75 hr of in air time before I lost the plane to the thermals but, I was HOOKED my brother too. My brother is still flying the same plane. we flew it in wind gusts of 15 MPH Friday and still went home with it ( we did smoked the battries, they were hissing) with the orignal wings, fuse, and tail. these planes have no moving parts, 2 pusher props, used for climbing and turning.

Even though the expirence with the first plane took the edge off my first flight with the AB, it was still very stressing, and I did draw off all the expirence I got from my first plane. With out the expirence of the first plane, I don't think I would of been able to fly the AB. I bought 4 props, 3 wings, and 2 tails, for the AB, and I am still on the same set that came with it, maybe I'm wrong and the only thing my previous expirence gave me was, enough skill not to break the orignal parts.

anyways I had a BLAST today, I'll be talking my brother into buying somethimg with an elv. and rud. soon, so I can have a chance to teach him Hee Hee Hee ( you have to know us both to understand the joke).

this was my day and my $.02 worth



CaptainRandy -> RE: Does anybody fly Accipiter Badius in here? (7/18/2004 5:04 AM)

Hi Brent,
I am jealous, I went to my club field today to fly, but it was too windy[:o] here in Florida. I will try again tomorrow.
Sound like you have it mastered. Are you flying the flat of Poly wing?
I have flown both, but would only recommend the Poly wing for a beginner.
The poly wing not only flys eaiser for a beginner, but it also glides better and I can keep it in the air longer on a battery.
I am using the stock batteries, but I want to go to Lipo's. What batteries are you using? and what kind of flight times are you getting (without thermaling)
I think buying all the spares was a good move. It worked for me too, as I have not needed any of them except one prop that I broke on some asphalt. I missed the @#$% grass by 6 inches.
Lets here some more good news!
Capt. Randy[:D]

Thats great! I'm glad you had fun! My first rc plane was a badius with zero luck! so i bought a traner and learned on thta for awhile. I went back to the AB and she flew for me! Its well worth the price!



Pilot Ray -> RE: Does anybody fly Accipiter Badius in here? (7/19/2004 10:06 AM)

I really like my Accipiter Badius the more I fly it and I wanted to give some input to other beginner flyers of the Accipiter Badius for a more successfully flight. My plane originally came with the straight wings and I was continously from day one fighting a severe right banking problem upon takeoff that always ended in instant hard crashes. It did not matter how well the plane was set up, it just would keep rolling right (from takeoff) as it climbed to about 25' and would preceed to keep banking untill it would crash hard. To make matters worse, my plane seemed as though it was accellerating much faster than I thought it should be and made the crash impacts that much harder. To keep a long story short, I discovered that the problem was the straight wings and an apparent defect distortion flaw that was uncorrectable regardless of how I attempted to straighten them. Also one side's wing was slight heavier than the other side's wing of did not help things. After taking CaptainRandy and others advise on the forum, I decided to try the Polyhedral wing on my plane for the first time today. I was truly amazed that on the first attempt that the plane actually went pretty straight and was now 100% steerable and actually flying. The plane now has a slightly slower takeoff of which helps allow for more steering correction time and is 50% more stable. I did put the new Poly wings to the crash test today by accidentally crashing my plane several times from 20' high stalls due to too heavy of a wind. After sometime, I eventually figured that out after some circling around and when heading back into the heavy wind, the plane would start to shake and begin to nose up, But yet it was still controlable and easily allow stall recovery as long as I was about 30' or more above the ground. I really like the new Poly wing and it also will take the crashes better. The reason it takes crashes better is that the new Polyhedral wings are a one piece wing that mount lower and fit better on the fuselage. Also with the wing tips being designed up on the ends, The wings take the horrible looking cartwheeling type crash better. I'm excitedly looking forward to flying my plane on a more reasonable less windy day and I would definitely recommend that a Poly wing should be used first when trying to learn to fly the Accipiter Badius plane before trying the faster flying, advanced flyer oriented straight wing. Now I'm looking for information on whether there is any type of safe paint or very thin stick on colored coating that I could use on my planes wings since a white plane is some what hard to see at a distance.

Thanks Ray



lduford -> RE: Does anybody fly Accipiter Badius in here? (7/20/2004 1:43 AM)

hi guys i also am enjoying my ab still having control problems the plane seems like it always banks to the right i wonder if the poly wings would be better where can i buy them? thanks



CaptainRandy -> RE: Does anybody fly Accipiter Badius in here? (7/20/2004 5:33 AM)

Hi Ray,
Congrats on the flying with the Poly wings. I told you that you would be successful with them.
Wait till you try them on a calm day. Did you see my other posts to you 136 & 137?
I replied to you about the posting of pictures and I also sent you an email at the same time.

Those looking for the Poly wings can get them from raidentech.com, but make sure you specify Poly wing, as they sell both.

I went flying the other day at my club field and it was a bit too windy for the Badius, but I just couldn't resist. I got her up with no problem and had her thermaling for about 20 miniutes, my neck was getting tired, so I brought her down for a landing and of course now it was even windier than when I took off. I kinda lost her into the grass just off the runway. I thought it was the wind and me at the controls. When I brought the plane to the bench, I discovered that I had no control of the plane at all. I thought I had damaged the receiver upon my ever so slight hard landing, but I discovered that my Transmitter battery was DEAD! Wow, that was another close call. I charged her up and the next two fligts were FANTASTIC. She can really fly in the wind if you can get her up high.

Anyway, glad to here you are off and running with the new Poly wing, and I'm glad I could give some good advise.

keep em flying,
Capt. Randy
