Hey I just got my hyper 7 converted today, and I've got all the hardware mounted. I've got a little problem tho, whenever I start to plug the batteries (12 cells) into my esc (9918) it sparks at the connection. I don't want to try to drive it if it is going to short my batteries or screw up my esc. I just hope I haven't screwed it up yet. Any help would be MUCH appreciated.
