RC ERA C138 Receiver Board Flight Controller with Gyro & Optical Flow Module
Restore Optical Flow Hover, Fix Signal Disconnections, and Eliminate Flight Instability
A burnt, moisture-damaged, or signal-dropping main receiver board on your RC ERA C138 6CH RC Helicopter completely grounds your aircraft. Hard crashes or electrical surges can damage onboard optical flow processing chips and 6-axis gyro sensors, leading to erratic auto-hover drifting, unresponsive servo movement, or complete failure to bind with the transmitter. Installing non-factory flight controllers destroys the pre-calibrated optical flow positioning and altitude hold algorithms. This official RC ERA C138 Receiver Board provides a direct, plug-and-play factory replacement. Pre-loaded with official C138 firmware and micro-connector sockets, it restores rock-solid 2.4GHz signal reception, precise hands-free optical flow hovering, and crisp 6-channel flight responsiveness.Ships worldwide.
Product Highlights
Integrated Optical Flow & Altitude Hold Module: Pre-calibrated sensor circuit maintains pinpoint indoor/outdoor hover stability without manual pitch or roll corrections.
6-Axis Gyro Auto-Stabilization: Advanced gyro processing delivers instant attitude correction for smooth 6-channel flight handling and precision control.
Factory Micro Servo & Power Connectors: Features dedicated pre-soldered pin sockets for instant, solder-free connection to main motor leads, tail motor, and servos.
Compact Lightweight Form Factor: Custom PCB footprint seats perfectly into the internal chassis mounting bay, maintaining exact factory center of gravity.
Securing Mainboard in Chassis: Apply thin double-sided foam mounting tape and seat the RC ERA C138 Receiver Board flat and parallel to the helicopter baseplate inside the main chassis frame.
Connecting Motor & Servo Plugs: Carefully plug the main motor lead, tail motor wire, and micro servo connectors into their corresponding labeled board sockets until fully seated.
Transmitter Re-Binding Procedure: Turn on your transmitter, insert a fresh 3.7V battery into the C138, and wait for the onboard LED indicator to turn solid, confirming signal bind.
Pre-Flight Gyro & Optical Flow Test: Place the helicopter on a flat, well-lit surface, perform the transmitter stick gyro calibration sequence, and verify stable optical flow tracking before launch.
