Hi Martin

I had speed brakes,which were fitted on top of the wing,but never had a chance to test them,because the model crashed on its maiden flight. The crash was caused by the gears on both of the aeleron servos,which stripped their teeth. I have thought of flaps for my bigger version,which I am going to build. The NACA design wing profile is good and this is why the model just wants to keep on going. I normally land it in a "dead stik" condition,especially if there is no wind.

Regards
Craig
