Reverse tail rotor rotation?
Is there any way to reverse the rotation of the tail rotor on a Hirobo Tow Cobra? If I set it up according to the instructions with everything 90 degrees it doesn't work. This is probably due to that it's rotating(seen from behind)forward. Is it suppose to rotate forward? Might I have done something wrong in the assembly?

Any suggestions appreciated.

Is it shaft drive or belt?

Jeff has one but I doubt he checks the scale forum, PM MRC-Hirobo and I'm sure he can answer.

on my mini titan its belt driven, the belt was twisted the wrong way when installed so to save the change i put the blades on back to front.then had to reverse the tail servo to correct the problem.

as long as the blades, and control direction is correct for counteracting torque, it doesnt matter what direction it turns. now if you want to keep the direction of rotation scale as per fullsize , then you will want to check to see what you can do. i am not sure about the hirobo system but on the xcell t/r gearboxes which i use a lot, the output shaft's gear can be relocated to the opposite side of the input shaft's gear to reverse the direction. i always recomend that after rversing the rotation of tailrotors, set up your tail system again from the start to avoid confusion. check control direction, tailblades for proper installation direction, and gyro operation. dont ever assume everything is still okay from the way it was setup before the change.drive a rotary, fly a rotorcraft
