RE: What is the function of crow?
1320FB, David Gladwin, Gordon W, and Harry C, good job!!
Reflexing ailerons won't ALWAYS improve wing aerodynamics, without or with flaps (crow). Each aircraft is unique, YMMV, and so on...
Don't tell the folks at Robertson (STOL mfgr) that drooped ailerons don't work. They didn't get the memo, have been carrying on for decades. [X(]
Crow works great on my Stick 40, but with a fair amount of power and MINIMAL aileron use. Lands in 10 feet.
Give it a try, works in some cases (but I gotta believe a small amount of flaperon would benefit most cases).
