my tail will hold in hover, but the second i punch the throttle, it steps out to the right and stays. the tail will keep rotating if i keep on the throttle, or pump it. my servo is a jr ds3400. i have tried to center it mechanically, and also set it up in normal mode in hover, moving the servo back and forth on the boom. both ways, i get drift when i hit throttle. my speed control is quark 33, tried with and without 6v bec, same results. I have tried different motors too, rearranged electronics on the heli.
okay, the only thing that worked is changing the tail servo to an hs81. i did try the jr servo on ds and normal mode with the same results. Is the servo bad or is there anything else i can try?
nevermind, i figured it out, moved the ball further out on the servo horn.
