RE: Aerobird Challenger Advice?
Propbuster,
I set my control lines on the inner most hole of the control horns. I put a drop of locktite on the screw that holds the control line thumb wheel and tightened the screw as much as possible. This eliminated the tendency of the thumbwheel to "creep", allowing the control lines to become loose. Make sure that the rubberband that pulls on the control horns is in good condition. After a while they lose their elasticity and the controls stop responding properly.
You'll find that the AC is fairly slow compared to your other planes, but the ProTail makes it fun to fly. Keep us updated.
