I do not know that radio or gyro, but think I can help you basic questions.

Everyone sets up heli diffrently, so with that said, here is my R50 starting setup.

first off there is a 3D linkage guide in the raptor manual for refrence.

Set your transmiter collective stick to the middle and set your collective servo arm to be 90 degrees from the linkage. Now set your linkage so you will have your pitch at 0 degrees. There is a neat guide on the main frame to see this. This will give you equal and max throw in both + and - pitch ranges. Now adjust your radios atv setting so that you are getting full throws without binding the servo, this should give you about +11 to -11 degrees of pitch.

Basicly set you for/aft, and right left the same way. With the stick and servo at its netural position, set up you linkage to be equal in both dircetions on the servos.

This should give you a good base and ballance to start with.
