I have a Hangar 9 Twist 40. I originally had a Saito 82 on it and worked for a while and couldn't get it to do any High Alpha Flying. Thought that maybe it could be the engine is overpowering it. Smallest prop I could get on it without the engine sounding weird was a 14x4W. I then progressed to put a OS 55 AX two stroke on it with a 12x4 prop. Seemed to do better, didn't feel overpowered but would pull out of a hover. I have all the throws set to the 3D setting the book said so I have enough throw.

Now for what its doing, Knife Edge, it pretty much will not do a KE. Dips hard and wants to roll on to its canopy. I think the vert CG may have something to do with this. When I try to do rudder circuits, once I give it rudder and its flat, it almost points the nose straight down. What has me more confused is that it will not harrier for nothing. At idle it will fall out of the sky, but with some throttle it wants to fly instead of stay post stall. I have the CG, with no fuel in it, right on 5 inches back. The furthest back the book says. Ive worked on this forever and haven't gotten it any better.

I don't know if this is where this should be posted but hopefully I got it right. Any help at all would be GREATLY appreciated. I am at a loss for what to do so I am putting it in the hands of the internet

If I left out a key piece of information to help determine the problem, just let me know and I'll fill it in.

Thank you Thank you Thank you,
