Re: Motor Switches

Just in case someone thinks this is still a good idea, the FETs in the speed controllers are good for 65 amps each. Times three, that is 195 amps on a good day at room temp. A Chalupa has a stall current of 129 amps so two would be 258 amps, more than 60 amps over max for the FETs. Goodbye little Victor! That is why the rule is written to use only one motor per Victor so there is no smoke obscurring views at events.
