Gy240 is installed!

Ok, I got some kind of logical response from my new Gy240 on the Axe tail motor, in a static bench test with the mains unplugged.

I set the Gy240 Gain to about 25%, and put both the On and Rev switches UP.

I guess I am ready for hovering trials, but am a bit nervous

I got no response until I adjusted the 3-in-1 board TR Trim to about 50%, and I assume that the Gyro Gain should be Zero there.

Any tests or pre-flight confirmations you can think of before I try this thing?
