Finally i flew the chipmunk. it flew great, however when i would do a vertical climb it would pull left it needed full right rudder to track it straight. Do you guys think that i need more right thrust? I did notice that the vert. stab has a slight twist (warp) in it pulling the top of the tail to the left. I had to trim in some right rudder to compensate. Could this be the problem? If so any correction ideas. The gear is a little weak bouncing around alot on the grass landings were smooth.
