Common questions about manuals, registration, and support for this brand.
Turn on both the transmitter and the receiver. Press and hold the binding button on the receiver for about 3 seconds until the LED flashes quickly. Once the LED stops flashing and remains solid, the binding is complete.
Quickly press the binding button on the receiver 3 times. The LED indicator usually changes color (e.g., green for normal mode, yellow/red for gyro mode) to indicate the switch.
If the wheels correct in the wrong direction, press the binding key on the receiver twice quickly. The LED will flash to indicate the phase correction is complete.
Most DUMBORC receivers (like the X6F/X6FG) support a voltage range of 4.8V to 10V, allowing them to work with high-voltage servos.
The transmitter alarms when the battery voltage drops below the safe threshold (e.g., 4.4V, 7.4V, or 10.8V depending on battery type). Replace or recharge the AA or LiPo batteries immediately.
