I crashed my helicopter last September. It took me until this spring to be able to get all the parts I needed to fix it. I not only replaced what was damaged in the crash but a lot of parts that showed a good bit of wear on them. I bought this helicopter used and was told it hardly had any time on it. Oh well live and learn. It was still good since I did have a nice gasser helicopter. After installing all the parts and getting things adjusted the best I could it was finally time to fire it up and try it out. I could not get it to stabilize, like the gyro wasn't working at all. I tried a lot of things and ended up calling Chris Bergen for some help. He filled me in on several things that I didn't know but it still didnt' seem to make much difference. The gyro I am using is the Futaba Gy401. The directions that came with it says to set the one switch to normal flight if your main blades spin clockwise so that is where I left the switch. After many attemps to fix the problem I figured I would try something silly. I set the tiny switch to reverse and low and behold the helicopter began to fly pretty good. After that I went back and re-read the instructions and each time the way they read I have things set wrong but they work. So after much time I am finally back to getting to fly my helicopter. With the new engine, and all the other parts this thing is sweet to say the least. Talk about a well made, nice machine.
