We have maybe found why the ninja is not flying as it should!
Today when i came home me and a buddy were discussing the ninja. He said he has seen them fly and that theyre' great flyers (i honestly don't doubt it one bit i just wonder(ed) why mine doesn't want to fly right. Insidence might be the problem. It seems that when i made the hole fo the nylon screw i pushed the wing forward and the leading edge of the wing is resting in the higher part of the wing saddle thus giving positive insidence...I think i fmove the wing to the propper location all DFP's should go away! Do you guys thing this could be it?? I did give the plane a few cool low passes and the thing had major speed and yes it rolls like a jet! but that was at a very fast speed.
