I used a similar setup for a while (fair warning it’s exactly as obnoxious as you’d expect to have such a big remote for esk8)
Yeah, you’ll just need a JST2.0 crimping kit, then crimp the little pins onto the other side of the receiver wire so that it fits into the VESC, line up the pins for +, -, and PWM (might be labeled ppm on the RC receiver) From there you can use it like any other esk8 remote.
