I just bought a Castle Creations 1/10 Mamba Max Pro SCT 2400kV System and did not realize that it did not have a built in usb port to program. It looks like you have to get a field programmer to do it. I have a Thunder charger that has a cable that is the 3 pin that plugs in to the temp part of the charger so I can be hook to a PC. I was wondering if any one every used that to program there esc. Thanks.
