reflex / speed flap

[yclui]

Hi,

I have tried in vain to get the info. from the net. Can anyone direct me to related internet resources pls ?

I would like to gain some understanding into the working principles behind speed flap and I am planning to try it out on my F3F ship ( a Pike WR ) after getting a decent transmitter for gliders.

Thanks,

Y C Lui

At this site you can compare the polar plots of several airfoil flap positions for the few airfoils where wind tunnel test data is available.
