Luna-tic currently runs on hobbywing quicruns 860, the duel (double output for two motors). Worked fine for 8 fights at Manchester. I say fine and currently, the bot can turn while speeding up or slowing down, might be something to do with the greater resistance when the esc is "reversing"...?! I'm not an electrician. lol. I will be getting One of Rorys ESC's (which controls both the left and right motor) when money permits. And for the price of £55 (last checked) its the same as two quicruns anyway. I do read Rory can get quite bogged down building and repairing ESC's, so best to message him to see what his current work load is like!!
