Thanks a lot Deadeye, You are correct about the flaps. This plane floats a lot as it is. The flaps do help stablize the plane more on final not that it is an unstable aircraft at all. The flaps just puts it on rails for the runway so to speak. The YS .91FZ does pull this plane with amazing performance. I am able to do a knife edge loops easily, flat spins, inverted flat spins, walls, parachutes, waterfalls, blenders, etc... With my 1" addition to the rudder, elevators, counter balance rudder and having my CG about 1/2" pass the recommended position also is a plus, so hovering and torque rolling is not a problem at all. The only downfall is once it flat spins, it will continue on it's own even after you try to stop it, but it is a true FLAT spin so I have to stay high to get it out of the flat spin. Unlimited vertical is a very real fact. Once the plane hops off the ground you can point the nose up and continue until you get dizzy. A buddy who flies with me is a policeman who radared my 4*60 doing 116 mph.

How does the coroplast version fly? That is very impressive. Looks just like the original.
