REFLECTOR: Vortex Generators

[Lawrence Epstein]

I would not put VG's on the Canard without also putting them on the main
wing. (without some real engineering input).
If you do put them on the canard, be very careful about your flight
testing.

A main feature/requirement of a canard aircraft is that the canard
*ALWAYS* stalls
before the main wing. If you enhance the lift of the canard, the main wing
might stall first, leaving you in a deep (unrecoverable) stall.
