RC ERA C138 Transmitter Mode 1/Mode 2 Remote Controller for 6CH RC Helicopter

Restore Precise Control, Replace Faulty Transmitters, and Choose Your Preferred Throttle Mode

A damaged, water-affected, or unbindable remote controller for your RC ERA C138 6CH Optical Flow Positioning Helicopter grounds your flight sessions and prevents smooth hovering, gyro calibration, and speed toggling. Pilots often struggle when forced to fly an unfamiliar stick layout—flying Mode 1 when used to Mode 2 (or vice versa) leads to muscle memory errors and high-speed crashes. Worn potentiometer gimbals or sticky switches cause control delay and unpredictable stick response during indoor and outdoor scale flights. This official RC ERA C138 Mode 1 Mode 2 Transmitter delivers an exact factory replacement. Available in both Mode 1 (Right-Hand Throttle) and Mode 2 (Left-Hand Throttle) options, it lets you select your preferred flying setup for maximum comfort and precise flight stabilization. Ships worldwide.

• Binding to C138 Helicopter: Place the C138 aircraft on a flat, level surface and power it on until the onboard LED blinks rapidly, then switch on the transmitter to pair automatically.

• Verifying Throttle Stick Function: Confirm that your chosen stick configuration (Mode 1 Right Throttle or Mode 2 Left Throttle) responds smoothly before spooling up the motor.

• Pre-Flight Gyro & Stick Calibration: Perform a quick manual stick calibration on a level surface to zero out gyro drift before initiating one-key takeoff.
