PS - CG is where those two little pin-holes are in your top pic.

My surfaces are set up this way:

Top hole on the aileron servo horn second hole in on the aileron surface horn - low-rates 60% throw, 10% Expo - high-rates 100% throw, linear Expo.

Second hole in on the elevator servo, second hole in on the elevator surface horn - low-rates 85% throw, 10% Expo - high-rates 100% throw, linear Expo.

Once you've got it up and flying and doing some nice easy circuits, power on out of a dive and hold it level flat stick about 50ft above the ground - then pull dead-vertical right above your head and flick high-rates on the aileron and give it full roll and watch it spin like a top towards the stars
