Hi,So you will be ground switching power to the ESC's, what is controlling the speed of the ESCs?
Because of your load being an ESC with some controlling circuitry attached, you may have to high side switch the ESC On and OFF.
Thanks.. Tom...
No the motors are just general loads, I want to make that e switch to contain the whole system and turn it on and off with a small little switch sins there are not alot of switches that can handle that that much current that are of a reasonabke size.
