Hi

I have been thinking of making these for a while and by reading the discussion forums there seem to be a couple of options outlined here

http://diydrones.com/forum/topics/angle-of-attack-sensor?id=705844%3ATopic%3A78347&page=2

There seem to be 4 options

a)A rotary vane connected to a Hall effect sensor/low friction pot

b)A diode laser(not a clue about this)

c)A 5 hole probe(Seems interesting and doable)

d)Mark Drela's idea of having pressure taps on the top and bottom of the wing to figure out AOA

Has anyone tried these options? I am starting a new topic because the above link is about a year old.

a)How would a rotary vanes position be affected by aircraft attitude or rotation. I would think that these effects need to be removed before measuring AOA/ sideslip

b)Seems most elegant,

c)How would this be calibrated?

d)If i don't know the exact airfoil shape, this is a bit complicated.

Have any of the RC folks had success with these methods?
