I strongly agree Robotech! I don't use 2-56 anymore except on the throttle. Especially if I'm going to 3D! We do not want flex. Just to make you feel better, I put mine in... was on the deck, pulled to the vertical and 15' up my engine stopped. Immediate stop of forward motion, just flipped to nose down and hit square on the spinner. [&o]. I set it aside to be worked on later.
