I'd still love to know how you will accurately calibrate your device, as per my first post!
You've told me why you you've bought one, already!
The 4 or 5 SuperCubs that I have flown have all stalled as the the needle recedes to zero, power off. Full power stalls - I am sure that the needle was tickling about 35-40 mph. At that power/speed/alpha combination the stall was very evident.
Langeweische is a sort of hero of mine, hence my monniker! As an aerobatic pilot I find him and AoA indespensible. I really wish you well with your weight/drag increase and would still love to know how you will calibrate it.
God forbid I like the answer so much, I might even install one on my Pitts! Okay - that was a blatant lie to dissuade Kirstey from her persecution of a fat old bloke!
