FAQ

Please install the [USB driver] and try again.Please contact us to get the driver.
After connecting, the mouse moves and cannot communicate. What's the
matter?
Please power the Ground Unit first, and then power the sky Unit. If the data at the other
end is transmitted to the USB when the USB is started, the computer will automatically
install the Microsoft mouse driver.
Sometimes the P8 indicator will turn off does not work?
Please make sure that the maximum current input at the power port is greater than 2A;
Otherwise, the P8 may be stopped; It is recommended that the ground unit use
independent power supply instead of flight control power supply (connect V5 + flight
