As long as we are talking about flaps on gliders....what is the preferred
method to getting the curvature on them? On the std CLG I built for the
PPCC I wet formed them...they were balsa, what is the method if using Depron?

I've done it both ways and have had good and bad gliders built both ways.
I think Stan's Slow Poker started this method. Drela's Upstart has full
span flaps. Two of the talking points for the rigid tip are that it produces
washout in the tips (relative to the rest of the wing) and helps control
vibration of the flaps.

<WBR>All the category 1 flapper type standard catapult glider drawings I
have show the training edge flapper free to flex except at the wing tip
where it is attached to a ridged wing tip section. This would seem to limit the
ability of the flapper to flex. I am curious why this is? Wouldn't it be
better to not restrain the flap at all?
