The power switch on my Speed Passion Reventon R broke somehow. It has the bind/setup button on the switch so it is a 3 wire. Does anyone know of a place in the US that has spare switches in stock? if not, is there a 3 wire external power switch that might work?

I can't be 100% sure, but since Hobbywing makes most of those ESC's(& Orion's also), you might try this one: http://www.falconsekido.com/products/esc-switch ,it is a 3-wire switch, so I'd think it has a decent chance of working....

Thanks! That will work perfectly.
