I have installed a mercury srs with futaba sbus in stead of a receiver and 3e which has been working fine, this is in a sports jet, but we are finding when the turbine is on full throttle the rudder elevators and to a less extent the ailerons jump about, its like the gyro is vibrating, but it’s fixed down solid to the radio tray, the gyro has been set up using the flight mode switches and setting manual figures for damping, that all works fine it’s jist this problem with the surfaces when on full throttle, please
