RE: help with my slo-v
If the tail assy is flexing that much, you probably have the C/F fuselage broken a lot worse then you think. This could also be causing your nose up condition, as the tail is not being fully supported by the fuselage, in the air. Instead of the fuselage holding the tail secure, the tail is rotating up at the rear, due to the force of the air pushing it up, as the wing and tail are hold ing the plane up. How flight works, the wings support the bird in flight. The tail moving up,caused by failure in the fuselage, will cause an up elevator condition, as the fuselage is not holding it in place. In flight the fuselage instead of being straight, it looks more like a banana.
Motor should not be getting hot. If it is, it means excessive amp drawl. Binding in the gear box, or a motor going bad.
