Hello, I have never used the forums before. I'm having a problem with a helimax mx 400. I can't stop the tail from spinning counter clockwise. If there is any responses I will go into detail. Thanks John

There are only a few reasons for that, John- bad tail servo, tail sticking, gyro orientation reversed, or a bad gyro.

I don't know if it uses a belt or a torque tube, but whichever one it is, in addition to the suggestions above, you might want to double check that the belt or gears are working properly.

Good one, dragus. It's a belt drive, so making sure the belt isn't loose is a good idea.

Thanks :-). Oh and since it's a belt drive check the little pinion gear that's on the tail rotor shaft. Chances are that it's fine, but I cracked mine once in a freak accident lol. A crack can loosen it and cause it to slip on the shaft.
