Status: offline 		So here we all sit, having spent money on a Plane without knowing for sure how it will fly. Just betting on the good reputation of CA. I hope someone get's their's finished and flying soon so we can hear about it. I am hoping it is a great 3D machine.

22X10, 22X8, 23x8 ?

Thanks

The Stand off situation is that the red stand-offs come with European motors with metric threads-You funny guys have imperial threads in yours....

I have two kits arrived-probably go electric with both but may go ZDZ40 (23 x 8) in one as I have these from Graupner and the cyclinder doesn't stick out of the cowl as much as the DA 50.

I'm not fussed about the canopy as it sucks with a silver screen, i'll re paint it dark blue/black.

Only down side I see so far is the lack of down elevator available (though the elevator is large in size)

I agree on the down elevator. Full deflection is not that much and the amount of power to get the full deflection is a lot. I was pondering the thought of removing the lip entirely. What is your thoughts on that?

NO!

If you run a screw driver down the lip to flex it away from the lower surface, it's the bead of resin making the flex shield stiff. Once it's been pulled out a couple of times it frees up. Clean the inside edge with some fine glass paper or you will score the elevator finish.
I can get all the movement available without much servo strain-What is needs is the cut line on the lower surface off set more like the other Comp ARF stuff

Status: offline 		Got mine. Seams are terrible. So bad that I will need to sand them down allot before I try to hide them with vinyl. The canopy and wheel pants seams are so bad I will have to repaint them. Even worse, there are what look like bubbles between the plane and the mold. At the very front of the plane. This will require some body work and paint. This is not shipping damage, just poor QA. This bird could not have been inspected. If they had more in stock, I would return this and order another, but they don’t and I don’t want to wait a month to see how it fly’s.

As someone else mentioned, getting 45 deg down from the elevators is going to take some kind of modification. With the hinge line on Top, we will actually need more like 50 deg down to compensate, in order for good 3d flying. I don’t see this happening but will try with the help of my hired professional builder.

Other then bad seams (worse then what they say to expect), flaws caused by molding issues and a serious problem with down elevator range, all else looks pretty good. This is an early batch. I am sure they will get better. If it flies as good as I hope, it will be worth it. But unless we can fix the elevators, it won’t. (at least not 3D).

Status: offline 		The Exhaust can sits on the wing tube ? This looks like a vibration issue. Sits at such an angle the rear of the can sticks out of the fuse ( from whole we made) No way to get even close to 45 Deg down from elv. Rotation pins on main wing have allot of slop. Lots of yellow over spray on the Red paint.

Status: offline 		I have been working with CA and DA about the exhaust issue. If you read closely in the directions on page 22, they mention 2 optional exhaust cans. What I have (the TD75K) and one smaller in diameter the TD75. What we are planning to do is exchange the Can for a smaller one and exchange the header with one with a 50 MM Drop. The hope is (and I think it will) with the header drop it will reduce the angel of the can that is needed to clear the wing tube, and with the smaller diameter can, give us a little more room. CA and DA are being helpful in resolving this issue. I will advise when we get the new parts.

On the Elevator problem, we have it up to almost 45 degrees down deflection now. Not easy though. If you take away about 1/8 from the Lip, increase the angel on where they meet on the end AND remove some of the foam form the “bottom leading edge of the Elevator where is was hitting the bottom trailing edge of the hor stab”. There is some foam there you can remove.

Status: offline 		Dick Hanson, Howdy. At 1140 sq in the 2x2 isn't going to meet your standard for loading. History shows that these planes fly very well at heavier weights - I assume you have flown Ray's. That said, I have flown 2.6's at 25.5 lbs (mine) and one at 29 pounds and they feel exactly the same. We also have two 2.3's in Havasu at 19lbs and they fly a slight bit heavier than the 2.6 at 25 lbs, but still very well. No real differences until you are within ground effect on landing. Nothing like your creations, however.

My 2X2 arrived today. Looks very good with the exception of one 3/8" ection of the seam ahead of the canopy, and it will get covered with trim tape so no problem.
