Punisher3256 Hey man I’m doing the same thing to a toy crawler. I’m having a hard time getting my 4x4 to work. If I switch motor leads I can get either front or rear wheel but not both axels at once. I’m using a dumbo rc transmitter and a six channel micro receiver. How do you have it wired up into the receiver and what settings u have esc on? Thanks AJ from bc Canada

Psyklops Hey havn't got it working with my dumborc tx, don't have the new version tx to do the right mix so using a flysky tx and rx, a delta wing mix on tx, 50% ch 1 to ch 2 visa versa, yellow into ch2 on rx and note the position of the switch on the esc, one way is single signal, other is dual which is what you want. Modified mine by cutting positive supply track to the two chips at motor plug end and applying them with raw battery voltage separate to the mcu positive power supply. That way can actually run then at our over 5 amps. The mcu detects dips in supply voltage and shuts esc down before it hits 5 amp to motor, let alone 5amps to each motor, i think chip is rated at 7a continous off top of my head.
Tldr Sounds like your switch on esc in wrong position or broken, they are fragile and heatshrink makes it hard to switch. If broken your need to solder the two tiny pads of the switch together.
