My MoJo 60 has started makeing a noise at about 1/3 throttle or about where it hoveres at. I have a Mag 91 fs and it does vibrate (like most 4's on profiles) I have looked everywhere for the noise, if you grab both ailerons or the end of the wings it stops. Hinges are not broke, I think that the play in the linkage is causing a drum like effect on the wing. Anyone had this problem with there MoJo?
