Sounds like you've hit the torque limits of either your servo's, control rods or control surfaces. Be very wary that you haven't stripped a servo doing this as it could be fatal later on. Craig had the same issue when he first put the mini turbine on the back of a stryker, The wings are also much more flexible than on your funjet. It's time to get yourself some metal gear digital servos but I'd back off the speed a bit for the Stryker or reinforce it with more carbon and balsa control surfaces.
