There's much talk lately among E-AB Cub guys about Keller flaps blowing up with air pressure. That is, the angle of deployment is reduced by air pressure. I think my Cessna-esque flap controls will alleviate that problem but Mike figured it was simple to make a true flap angle indicator similar to a Cub's trim indicator. Here's the bones to the indicator. A sheathed cable with a barrel end and a few hand-made parts to attach and guide the cable is all it takes. The actual indicator won't happen until the interior is in place so stay tuned for that.
