First off I'm a total newb to anything RC. Duh, I posted in the beginners forum lol. Anyway, my HB when I start it up the tall wants to spin to the right real fast even with the trim adjusted full right. When I conter act this movement with the rudder it starts swinging back and forth rapidly, the motor speeds up real fast then slows down real fast and repeats etc... Also, I've tried adjusting the 4 in 1 mixer but the dang thing wants to strip instead of turn. Is there a way to replace those adjustment screws on the 4 in 1?
