Would be the same setup for brush type ESC. Cut the +,red wire on the ESC that goes to the batt. and install the Diode with the white ring on one end, towards the ESC. You can get the diodes from Radio Shack. The package I have says EPOXY RECTIFIER 3AMP/400 TIC. The power to the motor jumps from 3.7 to 7.4 volts. You will likely need a different motor that will hande the higher voltage. Hope this helps.
Actually it is not the same with the stock brushed system....[:-]
you have a - and a + wire from the battery to the esc that goes to the rx/esc board and nothing else
if I put a 3.7V diode on that the whole system would see 3.7V, no way to separate the esc voltage from the motor
but if I could find a 4.5V or so diode then that could work on the whole system possibly??
