I have two old Mamba Max ESCs (not the Pro) that I want to run in a crawler I'm building. They run a brushless motor just fine but when I plug in my brushed motor (Axial 55T), all it does is pulse in forward and reverse. I know the motor is fine because I had an XL-5 running it with no problems. I'd really like to use the Mamba Max because I like that it can (or should) run brushed and brushless. I've followed Castle's directions for which wires to use, I've tried recalibrating the end points, I've updated to the latest firmware, and both ESCs still act the same. Any ideas?
