Futaba radio is diode protected to prevent overcharging, which means that the battery cannot be discharged through the transmitter.

Single stick design on the right side of the transmitter. Designed for aileron, elevator or rudder and throttle control. Proportional third channel slide switch on the front left side of transmitter. V-Tail mixing/elevon. An ergonomically designed transmitter case contoured to fit the pilot's hand, with a left-thumb recessed area, and an "S" curve shape for positioning the right hand naturally while operating the stick. The side-to-side stick movement follows the natural geometry of thumb motion at approximately a 10° angle. Servo reversing switches for 2 channels (aileron and elevator) are on the lower front face of the transmitter. The 3rd switch is for turning the "V-tail Mix" feature ON and OFF. Mechanical trims. R114F BEC receiver is included. 2-LED battery level (Green-full, flashing Red-low voltage). Charging jack is pre-installed for included Tx NiCd battery. Narrow band, excellent for adjacent channel rejection. One year warranty.
