I use a pair of female Deans connectors for the esc motor wires. I put the red and black motor wires on one connector (female deans #1), the white and a jumper from battery positive to the other connector (female deans #2).

This way I can run a brushless motor (two male deans, red, black, and white wires used. Batt positive capped off),

or brushed w/ reverse (one male deans connected to red and black #1),

or high powered brushed (two male deans used #1 & #2, red, black, and white spliced togeather on the motor side, and the batt positive).

One set of connectors (4 wires) on the ESC and whatever configuration I need on the motor side...


The MM could thermal the 6 fet's it uses for brushed w/reverse without seeming too hot at the heat sink. There are 12 fets in the circuit, 6 on each leg (leg #1= positive wire, leg #2= negative wire) 3 fets are active on each leg during opperation, of the 6 fets on each leg 3 are positive switching and 3 are negative switching. When the motor spins the esc is providing positive to one wire and negative to the other.

When you use high power brushed it uses 18 fets at once, on one leg of the motor wires, the other leg is straight to battery positive. Three times less of a chance of a thermal shutdown.


If I could only draw what I see in my head, then afford to build it, and finaly get to play with it...
