GMr is a 4-channel micro/mini car receiver, using AFHDS 3 (third-generation automatic frequency hopping digital system), single external antenna bidirectional transmission, micro size, and reserved gyro interface. The GMR receiver is compatible with RC racing cars and drifting mini cars.

Features:
* This 2.4CHz receiver with 4-channel is suited to DIY your RC car especially high-speed cars such as RC racing cars and drifting mini cars.
* The receiver is compatible with PL18/NB4 and NB4 Lite all the transmitters which with AFHDS 3 protocol.  realizing a strong anti-interference ability and quick response within 5ms, accurate response to weak signals, and active avoidance of co-channel frequency interference.
* GMR has a built-in gyroscope interface. After the gyroscope function is connected and activated, when the car structure has a virtual position, it can greatly reduce the sideslip on a straight road caused by it, and correct the direction of travel in real-time. Moreover, when turning rapidly, it can easily keep the car body stable and smooth, effectively avoiding any drift or rollover.
* Supports online upgrade, with rich functions constantly updated; Supports two-way communication, returning the status information in real-time; Supports 3.5-9V wide voltage input, breaking the equipment voltage limit.
* Warranty: If there are any problems, please contact our store in time. We will give you a satisfactory solution.
