On the opposite side of the spectrum, I'm considering goofing around with
some homemade VGs on my Fly Baby next year. Figured I buy a batch of 1/4 -
1/2" aluminum angle and cut up a batch. Anybody have any rules of thumb
regarding size, placement, stupidity of the idea, etc.?

Better Yet, Jim Price (altitude record holding Long EZ) shows how
to make VG's from a strip of plastic panel edge moulding. It cost
about $1 at Home Depot for an eight foot length. He offers instructions
on placement, IIRC we put two on 20 degree offset, at about 20 percent
chord, every ten inches or so. Better check with Jim.
You stick them on with silicone caulking. Work great at increasing lift.

I could fly so slow that my ailerons felt too mushy, took mine off.
He can fly at 50 mph.
