Double-check that all controls (aileron, elevator, rudder and throttle) move in the correct direction. Happy landings. Check the radio installation and make sure all the control surfaces are moving correctly (i.e. the correct direction and with the recommended throws). Test run the motor and make sure it transitions smoothly from off to full throttle and back. Also ensure the engine is installed according to the manufacturer’s instructions, and it will operate consistently. Check all the control horns, servo horns, and clevises to make sure they are secure and in good condition. Replace any items that would be considered questionable. Failure of any of these components in flight would mean the loss of your aircraft. E-flite Sobré 3D Profile Assembly Manual...
