Abstract:
During alignment procedures on the quad, it was found that pitching the top and UI masses caused permanent pitch changes at the test mass. It was felt that this may be
related to permanent lateral displacement of the blades tips. We could not produce a sideways set of the blades with the lateral forces that would be produced at the blade tip by a tilt, wiht any feasible value of clamp-bolt torque
