Mini Quark build

<< < (6/6)

Hi Keith,
           Thats exactly what I did, the reasoning being that the quark airfoil shape has a lot of undercamber at the trailing edge which make it glide well but under power it's like having flaps down, which force the nose up. When the ailerons rise it makes the section a more symmetrical shape. Anyhows it works remarkably well.

John.
