Thinking about glider projects other than flying...

If I add 2 instruments to the tail:

1) a 3d accelerometer
2) strain gages on the shank of the te probe to measure horizontal and vertical deflection

Then will the difference between these two be an indication of the left-right and up-down wind vectors?

The first would quantify, to some degree, how the aircraft responds to gusts(assuming no control input). This would vary depending on the natural stability of the ship, and CG location.
The second would measure the response of the probe to the motion resulting from the first. Effectively it would provide the same information once the mechanical issues of stiffness vs deflection are removed.
I'm not sure what might be gained from this information.
FWIW
