The stab pivot is not exact from glider to glider so the trailing edge measurement should be a relationship between the two. As a starting point I have always eyeballed it from behind aligning it with the wing. Regards Dean

Aileron differential in degrees is 15 up and 3 down. This was settled on after dozens of test flights with a camera and yaw vane. Used right stick only and 100% rudder mixed in.
