I have the replacement, but when I put it on, it spirals out of control. If I look at the original and the replacement, they look identical!
What is wrong and how can I fix it?
Answer
You need to make sure you have the tail rotor oriented correctly. It is possible to install a tail rotor backwards in some cases, which would just make your heli spin like crazy.
I could give you a better answer if I could see/knew exactly what type of tail rotor you have. However, generally the tail rotor must blow air to counter the rotation of your main rotor blades.
E.g.:
- if your main blades rotate clockwise
- tail rotor pushes the tail clockwise also
This stops the tail's tendancy to rotate counter to the direction of the main rotor blades.
Alternatively, depending on the type of heli, you may have issues with your tail gyro adjustment, tail gyro direction setting, or tail servo linkage adjustment.
Hope that helps

How does a Mini RC Helicopter work?
Chaz
I understand the tail rotor on a "typical" rc or real life helicopter is used to counteract the torque of the main shaft propeller, but that is not the case on a mini helicopter. The rear blade is set up horizontally (controlling pitch), so how does the helicopter stay steady (question 1) and secondly, how does it rotate left and right...this just boggles my mind! Its an small RC Hog Heli w/ two main rotor blades btw.
Answer
The 2nd rotor goes counter to the main rotor, which cancels out the torque. To make it turn left or right the counterrotating 2nd rotor is either slowed down to make it turn one way...or sped up to make it turn the other way.
The helicopter can only hover when both rotors are counterrotating to each other the same speed. Vary the speed at all of one of the rotors and then the counterrotating forces are no longer equal and the heli turns in the direction of the lacking torque
