Hi guys, I received the MMAX Pro ESC and 17.5t motor combo today. I had my LHS solder it up but I can't get the motor to work. When I go to calibrate it I get to the full throttle stage and the LED goes solid blue and then beeps 3 times. The calibration video and the instructions in the manual doesn't say anything about the 3 beeps.

I've reset my transmitter and set that up again, and I updated the firmware on the ESC and that still didn't help. Has anyone got any ideas or had this problem?

The only time I've had a failed calibration is if the sensor cable is either loose, faulty or not installed. I'd check that first with a new one. Also maybe try the receiver binding process again before doing calibration.

It was the sensor cable! Just needed to be pushed in to the ESC a little more. Thanks for your help!
