Feigao 540 9L and Warrior 9918 Controller

I sure hope you guys get this all figured out. I'm having the EXACT same issues (motor shuts off under WOT, or 2nd gear heavy throttle). Sometimes it just stalls out during a run.

I have the same setup Feiago 9L / 9918 / UBEC, black jumper off, beautiful soldering connections, 12GA wire, 14 cells of GP3300's, new radio system installed (JR XS3 Pro).

It ran perfect for 2 days, then I parked it for a few hours. It started acting stupid on the very next run. Controller became so hot it melted the heat shrink wrap right off (mostly). It was one of those mis-labeled 9918's.

My truck is fairly light, with upgraded drive train and steering, front bulk / front & center skids / ALU chassis brace.

I'm at my witts end with it all, and just ordered another 9L / 30150 Brushless Car Controller.

I've moved my esc mount as far from the motor as I possible can incase motor heat was effecting the esc. I don't want to melt anothr new esc.

Please let me know if you get this worked out.
