The 18SZH 18-Channel 2.4 GHz Radio System from Futaba features a helicopter-optimized transmitter (radio controller) and receiver that can be used to control a wide array of RC aircraft, including fixed-wing planes, helicopters and multi-rotors, and gliders. The transmitter features 18 channels and supports receivers with the S-FHSS, T-FHSS, and FASST protocols, such as the included R7008SB. The "H" in the model number indicates that the throttle gimbal is smooth rather than ratcheted, which is considered the preferred arrangement by many helicopter fliers – however, you can change to a ratchet system when using the transmitter for an RC airplane. The transmitter also defaults to the Mode 2 stick operation when powered on, where roll and pitch are controlled with the pilot's right hand while yaw and throttle are controlled with the pilot's left hand.
For 18-channel control, the transmitter features 2 side levers, 6 digital trims, and 8 toggle switches to accommodate almost any flight function you imagine. It is able to store settings for up to 30 models and features a built-in S.Bus programming link for optional S.Bus servos. Both the transmitter and receiver are telemetry-compatible, with the data viewed on the transmitter's back-lit LCD touchscreen and audibly reported via a headphone jack. The system also provides vibration and audio alerts for alarm conditions and low battery warnings.
