REFLECTOR:Trailing Edge Fences

[Dave Teter]

Jack,
I stand corrected. I thought that vortilons were a necessary airframe
component on our swept wing designs. I based this thought on thirteen years
worth of reading Burt's newsletters, the Central States newsletters, and of
course the builders manual that came with my 173.

It may be interesting for you to put a set on and evaluates flight/stall
characteristics.

Best Regards,
David
