I chose this ESC because: They were really cheap They supported reflashing with SimonK’s firmware They had their test pads in a row so it would be easier All it’s FETs were the same (N-Channel) Some wiring had to be done to match the pin-outs from my 10 pin AVR programmer to the…

I’ve been waiting for this so that I could start tinker with reflashing of ESCs and the Turnigy 9x that I had recently bought. I choose this one cause it had some built in protection (diodes) added. It was also voltage selectable (3.3V and 5V) via adding or removing a 0ohm resistor. I plan on replacing the resistor with headers and a jumper later. It comes default…
