There's been a problem to date with fitting them to prop singles - the propwash mucks up AoA measurement using conventional sensors. One wonders if it's significant that the aeroplane in the video is a pusher?
I had a quaint notion of using a vane/rheostat device under a wing coupled to some modified form of classic, 1950s fuel gauge. However, with respect for SSDs comment above I think two such systems are needed, one for each wing.
I am no electronics person and have little faith in the stuff, but a simple rheostat switch that can move a needle to represent zero to seventeen degrees over an actual needle movement of forty five deg can't be beyond the wit of mankind, at a sensible price?
I wouldn't utter the words "stall speed" in close proximity to SSD as that would equate to invoking the wrath of Khan! I've tried in the past!
