I am running the izi firmware still. Haven't found anything else. Here is a copy of the amazon message:

The manufacture said, the receiver's output current for the motor is 350mA. Your
motor may be 500mA or more. It can not provide more current and drop down the
power, cause the receiver reboot.
To resolve the problem,
1. change a stronger power board inside the receiver (DIY).
2. Use a relay to control the motor.

If you need any information to dIY the receiver, please feel free to contact me.


Best regards,

Cindy
