Hey guys. I fool around on G4 a lot, and I've been flying the Extra 300 and hovering and doing knife edges etc. I saw a video on youtube of a guy holding a hover and doing torque rolls etc with an avistar. Here it is:

What do I need to start practicing this stuff? Better servos? Will a tower .46 give me enough power? I mentioned buying the low wing sonic. Is that capable? If an avistar is, it must be, right? I'm also thinking about removing the dihedral from my tower trainer. Can I just saw down the center and drill out the wing joiner and fashion another one? Thanks!
