Bob, I really don't look forward to cutting or even just drilliing into the wings, they are old! And I don't have a glare sheild, must less space on top of it. But thanks for the info and advice. If you have any photos of the AFS device or its installation maybe you could post them here. I'll also try to look it up online.

And as for as a stall warning, that may be good also, but the feel of the controls and buffet of the airframe, (tailplane) are good ones that don't require looking at an instrument.
