MXC control throws

Can someone please give me the control throws. for the ailerons, ie how much up and down.
And also what is the center/neutral position of the elevator measured vertically from the bottom of the fin to the trailing edge of the elevator.

I'm out of town and away from my glider till Friday. If others don't get back to you I can then.

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.

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.

How about feedback on what I posted.
Share your CG location as well.

My control surface movements are:

Aileron Differential - 16 degrees up, 8 degrees down

Rudder/Aileron mix: cruise 90%, Thermal 110%, Launch 110%, Reflex 20%

MODES -Measurement in degrees

Flap --------------- 0 ----------------- -1 ------------ +4 ----------- +6.5

Aileron ----------- 0 ---------------- -1 ------------ +4 ----------- +5.5
