Well of course, the best is to use an AOA vane, like the jets use. The
biggest problem is where the jets conveniently mount it on the side of
the fuselage, on most singles, that's right in the prop blast,
rendering it useless. If you could find someplace to mount it outside
of the prop blast, then it would work great. But finding that
place......


I would like to see a vain mounted on each wingtip with two indicators on
the
glareshield.

I'd like to see how much difference there is in AA from one side to the
other
during steep turns, slow turns, and less than perfect rudder work.

Sounds like an interesting idea. Encoding the position of the vane would be
needed. One way might be to use minature shaft angle optical encoders ( I
tend to think digitally as opposed to analog) . I've seen prices as low as
$20 each. Put one on each wing tip mounted vane and as Jim says the rest is
easy. (If you know some good electronic tech). If you know the AoA for
stall, the output of the encoder could be compared to a preset number and an
alarm into the head set could easily be produced digitally. I've used a
combination of a modification of one of Jim's circuits produced for
Kitplanes along with some additional digital circuitry for a High/Low
helicopter rotor speed alarm and it works great.
