a-10 wing design

[rotccapt]

i am designing a scale A-10, Just curious does any one know if the a-10 has a flat bottom wing, semi semetrical or fully symetrical. i would like it to do jet aerobatics.

For modest aerobatics, a semi-symmetrical will work just fine.
The full-scale wing appears to have a cusp on the bottom, further aft than usual for an undercambered wing, mostly for postive g manuvering I expect.

The A10 Thunderbolt II has an undercambered wing, NACA 6716 on the center section, transitioning to NACA 6713 at the tip. This gives a low stall speed which suits its role as a tank buster. The ailerons can be reflexed upwards to reduce lift at high speeds.

GWS makes the only A10 model I know of which reproduces the scale airfoil. It is often accused of flying unrealistically slow, but the full-size A10 has a top speed of 440mph, which at 1:18th scale corresponds to just 24mph!

thanks for the picture this will solve other problrms down the road
