I don't know what happened to my aerohawk. during a preflight check, when i tested the right aeliron, the servo pushed up and just stayed there and mede the "ssssiiiiii" noise, it couldn't return back to level position. When the joint rods tilted a swash plate to the right or forward, the main shaft moved up a little bit. Does this mean the main shaft will separate from the main gear soon? pls help. thanks
