I basically took a piece of thick plastic, bent it into an L, glued it to the front of the frame and the battery tray. Then used 1 layer of thin padding I had and servo tape to secure it to the L bracket I made.

I was concerned if I didn't rest it on the battery tray and secure it well, vibration or movement would mess with the gyro.

Seemed to work. Heli flies great, nice and smooth forward flight. Inverted, not so good. Barely kept altitude the first time I tried it and the tail spun around fast. I flipped it back over and avoided the dirt by about 3 feet. No plans on doing that again soon although I am using the stock pinion because I stripped the threads on my 9 pin motor trying to mount it on the CNC frame.

I'll try it again once I get the 9 tooth in there.
