Who all got one of these? So far I have only seen info about 3 or so. Are we the only ones that go one? I was expecting to see more postings about this one.

If you got one post in, lets get some talks going about what everyone is using for powerplant/ servos/ etc.

Rongreg seems to be the only one posting any info thus far. There has to be more out there. I am trying to finish up a couple of projects before I start on mine, so i am looking for info.

Thanks,
Ryan

I just bought one. Kit looks great. Very lightweight. Dave seems to have included just about everything needed to complete. I have been in this hobby for 8 years and have never seen an ARF so good. Obviously flights will determine all and are a little while away yet but I have also built a number of planes from .40 size up to a Carden 35% cap and along the way a number of ARFs. I don't think I could build this plane any better then they have and I consider myself a pretty darn good builder.

I plan on bolting on a BME 50 which while overkill, is not that much more weight than the big Mokis and I know how to manage a throttle.

I have an RC America 80" Cap 232 with a Brison 3.2 on it that flys awesome. The Edge is roughly the same size but a lot lighter in construction.

We'll see.

Thanks XOrionFe,

I too have been very impressed with the ARF. Like you said it seems to have everything included. I couldn't believe there was even 2 bottles of CA.

I was thinking of a 50 size gasser also. I was originally leaning toward a DA or ZDZ. Now I am wondering if that is too much engine. Ths thing is light.

Keep us posted as your building progresses. I will hopefully be able to start mine fairly soon.

Thanks,
Ryan

Guys
Do you this this will work with an os 160? I know that I woun't get 3d performance but thatr is beyond my capabilities anyway right now.

Hey Ryan,

Happy to hear you got your Edge - how much do you think it weighs or will weigh when finished - what do they say it weighs?

Jim

The OS 1.60 FX might 3D this plane if you use Scimitar 19x8

Here is waht Dave Patrick says about the weight with different combinations.

---------------------------------------------------------------------------
We get a lot of questions about weights. Here is a careful analysis of the last prototype. Weights are without fuel:

Left wing with servo, aileron extension, READY to fly: 18.5 oz
Right wing with servo, aileron extension, READY to fly: 18.8 oz

Canopy complete with cradle: 8.4 oz

Wing Tube: 5.9 oz

Fuse with pilot, without canopy (small amount of fuel left in tank)
MOKI 1.8, 24oz Dubro fuel tank, Dave Brown Spinner, 20 X 6 wood prop: 168.0 oz – Total: 219.6 oz 13.73 lbs.

Note: A ZDZ 40RV with Ignition and battery is at least a net 16 oz heavier than the above – Total: 235.3oz / 14.7 lbs

Note: Use 2 elevator servos and push-rods add 3.5 oz net to the above ZDZ version – Total: 238.8 / 14.9 lbs.

Note:

With a Power Flite 1,800 ma battery vs the 5 cell Ni-Cad, minus 3.3 oz
Remove the Pilot we used, and subtract 3.0 oz
New TOTAL: 213.3 oz / 13.33 lbs.
Substitute the MOKI with a YS 1.40 or 1.20 with a simple exhaust and save another 12oz
New TOTAL: 201.3 / 12.58 lbs.
These weights were done at a US Post Office Nov 21st 2002, they are as accurate as practical.

Important Note: The above was measured on a final, flying prototype, assembled as shown in instruction manual. Balsa will vary in weight. There is no guarantee that you achieve these weights. In fact you could be lighter or heavier.

Summary: With care, you can have a 12.6 lb. Edge with a YS-1.20/1.40 or Saito 1.80 and have a fantastic performer with very low wing loading of about 23 oz per square foot. Add extra servos, pilot, a gas engine and weights can rise to 15 lbs with a wing loading of about 28 oz per square foot, which is still good for a 1/4 scale aerobat. There is a huge variety of options available to you.

Chose wisely.
--------------------------------------------------------------------------------

I guess I can try with the OS 1.60 FX which I already have. If it's not enough power, then I will get the Moki 2.10.

I have a new Moki 2.1 that I will probalbly use with this engine. However I have been debating if I should use 4 servos for the ailerons, and 2 servos for the elevator.

It seems that the info I have been seeing I should only use 2 servos for ailerons and 1 for the elevator (pull/pull), taking in consideration the weight. The only problem I have with this is flutter on the wings, and potential problem if pull/pull configuration or single servo goes bad. With 2 servos (elevator)least you are protected if one goes bad. Then I ask myself what is the possibility of this happening?

I am so confused!!!!!!!!

I know the feeling. I don't know if I like the idea of a one servo elevator. I think I am going to wait until I make my engine choice and get everything in and see how it balances out. As for the ailerons I think I will go with one servo each, but my concern with that setup is that the one sevo is all the way inboard on the aileron. I would preter the one servo to be closer to center on the aileron.

Ryan

anybody have pic's of the Blue color scheme?

I looked at the blue one in LHS. It looks kind of bad. It's insignia blue all over, like the blue on Laser. Too dark of a blue for my taste. I like the yellow much better.

Is anyone flying the Edge 540T 79" with a DA-50? Dave Patrick says it's too much engine, not recommended, but I'll bet there are folks with this setup. Is anyone out there happy they have this setup?

Check out these strings about the DP Edge: I would recommend emailing or private messaging those who say they put a large gasser on it to get their final conclusions!!!

Thanks. I've read those threads already, lots of back and forth discussion on engine matches but no conclusions re: the DA-50. I'll take your advice and email individuals. If anyone would like to post their conclusions about this setup (DP Edge540T 79" w/ DA-50) I'd appreciate it. Thanks.

The 1.60 FX will fly it very nicely. I had a 1.50 saito in mine and it flew it pretty good. It would hang it at about 3/4 throttle but not pull out. It was pretty quick and about 11.5 lbs. with the 1.50
I think you would be unhappy with the DA 50 on it. I also own a DA 50 and I think it would shake this plane apart. Also I used 1 servo for rudder and 1 for elevator with pull pull. I'd have to go down in the basement to look and see what servos they are as I can't remember but I do know they were 185oz digitals and I rung it out pretty good with them. never fluttered. DAM nice flyier you will love it.

Miloh.

I have the DP Edge w/ BME 50 up front very similar to the DA maybe slightly less power and weight and I have the DP Extra with an OS160FX. The BME is awsome power on the Edge and it weights in at about the same as the DP Extra at 14.5lbs. If you want to fly a plane that feels more like a jet turbine then put in the DA and manage your throttle. The OS 160 will fly it well for pattern and IMAC manouvers except Advanced IMAC where you need two flick rolls on the uplines the OS just wont pull the craft through that.

You do need to look into thrust angles with such a big prop I use a 22 x 8 MenzS I used a bit more right thrust and some are saying maybe more down thrus but I havent got that far yet still fine tuning her.

As far as Miloh's comment on vibration I have noticed that the modern Petrol engine have their vibration moments low down enough in the RPM range as to cause no serious effects to airframe either at idle rate i.e below the vibration moment or in flight where you are above the RPM that may cause vibration, indeed I think some big four stroke glow motors kick alot more than a well tuned petrol Engine.

Well I never did try the DA50 on the DP EDGE so all I can say is what I deduce from experience with it on another plane, So I'm a lot less authority than some one who has actually done it.
It's good to know it works. I might have to try it out. My DP EDGE currently has a Saito 2.20, Still working the bugs out.

Miloh.

Miloh

Let me know how the Saito 220 performs i.e weights RPM with prop etc , I was thinking about fitting one on the DP Ultimate or the Saito 180 but iam not sure the 180 will give me enough power.

Arron:

I wanted to try the saito 220 in the DP Ultimate, I noticed you mounted yours inverted, do they run ok upside down. Can you also say what bugs you found in the saito 220.

If I can get it under 13lbs all up I think this just might be the perfect match for 3D performance on the craft.

What do you think.

Hi All,

I've been flying the DP edge for nearly a year now with a ZDZ 40 and though this is a good set up, i'd have been a little happier with the model if i'd gone for the 50 instead, i reckon the plane would handle it no problem at all, i've got the 40 now though and it works just fine.

I do still love flying my DP edge a lot, and actually got rid of every other model i owned, since i stopped flying them all in favour of this plane, and i still don't regret getting rid of them nearly a year later, i'm pretty sure that says a lot about the model.

Looking forward to (hopefully) a great summer flying season here in chilly Scotland.

Cheers all,

Z

The Satio 220 will shake as much if not more than a 50cc gas engine, it's the nature of a four stroke single.

The New BME 55 at 34 oz bare will weigh less than the Saito even with a lipo battery and ignition. It will probably be perfect for the Edge.

Sky Pilot


I totally agree the BME 55 is a new bread of gas engine, its weight means it can be fitted to much smaller models than previous 50cc class engines.

Only problem I see is fitting it to the current line of 30% aircraft I would think you would have some balance problems.

Regards

Darren

Darren,

I'm sure I could find a way to get nose weight. For me the benefit of the 55 would be the ability to use a very quite muffler without weight or power penalty. The 55 with a quite muffler will produce less db than a 220 with the stock muffler.
