I want a 3D trainer that can do knife edge, harriers, waterfalls, blenders, flat spins, k/e spins. I have a CG Extreme 330. It 3D's well but thats all its does. Its damn unstable in normal flight. I can do all the manuvers listed with it but if I just want to fly slow figure 8's a few feet of the runway its a handfull. I'd like a plane that can do 3D on high rates but be real *****cat on low rates.
