I am new to the game and just crashed my LT 40 on the third flight after my solo when the rudder came off at takeoff. Things happen fast when the rudder departs the fus, and none of them are good I think. I fractured both motor mounts, SIG type, and I want to replace them and go to a smaller motor. I know the mounts should be centered left and right on the firewall, but how about vertically? What happens if the mount places the motor slightly above where it was before? Thanks
