It's probably due to you trim/EPA setting on the tx. Make sure the trim is at 0 and the EPA is at 100-120% for both forwards and reverse. If the ESC doesn't see a good neutral/rev/fwd signals, it won't work.
I assume the receiver has already been successfully bound to the transmitter right?
Dumb question, but did you calibrate the ESC to your radio first?
I was trying to calibrate the ESC with the Sensor but it won't recognize the Sensor. I changed the arm time to 5 second with the castle link, still not it.
I connected the servo on the steering and the receiver is working with the Sensor radio just not going to the program mode on the MMM V3. Thanks in advance for the response guys.
