I dont know much about them, but i did read an article in rotorworld magazine about it and they didn't like the governor. They said it was slow. Thats all i can really recall them saying about it. I have no personal experince with them. Most guys use the Revlock, Throttle Jockey, GV1, and a few others i am leaving out. You are the first i have heard to use thunder tiger's governor.

Give me (and others reading) more information about your problem. We may still be able to help. We need details like, what kind of heli are you setting it up on? What kind of engine? What kind of receiver? How many channels? What all have you done so far? Can you tell us what is giving you the problem, such as, does it even turn on? Are you sure you have it plugged into the right channels? That shoud get us thinking about how we can help you.
