We've created a missile with the plane maker. We added a pusher motor with two propelers (1 CW and 1 CCW). Under 150-160 kias we have no problem with the gyro but if we go above it the gyro on roll (P) has false data. We've tested it aswell with a rocket engine and even with we dont turn it on it has false data above 160 kias. If we remove the motor this problem does not occure even above 160 kias.
