Aircraft Spruce sells three different AOA's.
One uses a probe under the wing, one measures the difference in pressure above and below the wing, the third uses a vane in the airflow to measure angle.
Does any one have experience with them?
ie:
Ease of installation
Ease of setup
How suceptable to damage
Do they allow accurately for flap selection

I assume the accuracy of each is acceptable

Most large a/c use the vane type, is it inherently better?
