Well I talked with my LHS and this was tried.

All connection's were tested and everything is hooked up correctly.

New speed control added same thing no gain from the tail.

Then the gy240 was tested with a different gyro initializes fine.

My questions is would E-Board screw setting have anything to do with this I had recently installed a new E-Board from factory, could that be not set properly and causing 0% tail gain?

Or should I use a smaller speed control ? 7am ESC instead of the 12amp ESC? or maybe even higher? 25amp?
please if you have installed a gy240 on your axe cp and input would be helpful.

Thanks in advance and a big thanks to PilotLight & blvdbuzzard.
