GP 580 Chapman cowl - HOW DO YOU GET IT ON!?!?!?!

[Eury]

Yeah, you save a couple hundred bucks, but to me the big thing is that you save weight, and it'll pull less power, so you can use smaller batteries (or just get more flights per charge), it all adds up.


I don't have any video, sadly, mine is one of the ones with weak wings, I came back from a day of some hard flying to find a bunch of loose wood rattling around in the wings. I pulled my stuff out of it, and it's just a pretty decoration now. At some point I'll pull the covering off the bottom of the wings and fix them, it was a great flying plane, sadly the wood or the glue that's around the wingtube wasn't up to par, because I broke a bunch of ribs in there.

I can attest to that!

Yeah, I saw your video, I have a feeling that the next flight I would have had one of those. I was really beating on the plane that last flight doing full throttle knife edge to knife edge snaps and other things that tend to break planes (what can I say, it was a bad day, and I was getting my stress out), and when I took the wings off I could hear a bunch of wood rattling around. Oh well, it's a pretty decoration until I get around to fixing it or buying new wings.

Hi!

So you mean I have to strength it a bit around the wing tube hole? To be honest for Bulgaria about 3500$ is lot of money so I want it to be as much safe as possible.

Yesterday I was calculating the total price... It got somewhere about 3500$ including everything. If using twin servos per aileron I 'll need a Smart-Fly equalizer II I think. If not mistaking I'll need 2 x Equalizers to put one on both wings. I don't think there will be any problems with the weight because the 3W 106B2 is more than a monster for this plane. Now I am thinking over another possibility - buying a bit more expansive Powerbox, let's say Smart-Fly EQ10 , which has built in matching capabilities for all servos, so I'll save about 80$ on these equalizers II. What do you suggest. I'' buy a Futaba R149DP receiver PCM - 9 channel. I plan using 2 x Li-Po 4600 Mah batteries on this plane plus another 2000 mah for ignition.

Regarding the servos I am still wondering is it worth the economy. Maybe in all cases twin servo installation is more reliable, because the second servo handles the pressure near the wing tip when helping the inner aileron. I think Smart-Fly is best choice regarding the power distribution of the plane.

I am interested to hear other peoples settings and installations on this plane.

Let's say I am pretty curious about the CAP 580 of hpapilot. Please could you write all details of your CAP - batteries, receiver, power distribution ,servos.... prop, weight, CG...?!

Best regards!

Dunno what you should do to strengthen it, you should obviously go through all the glue joints you see to make sure they are done well, but as far as the wing, I don't know how much you could do without removing the covering. Maybe pull the covering off on the bottom, and check all the glue joints and quality of the wood. Not everyone has had the wing fail, but there are enough of us that I'd be concerned.

really look at the glue on the landing gear plate and around the engine box.some of mine was not even glued.
