I had the same problem on my Belt CP, and when I got my Exceed ESC, I cut the ones that were on the old ESC and soldered them to the Exceed ESC. I haven't had any problems out of it, but you could do it that way. You can go buy those larger ones and put them on your motor leads too. I've done it both ways in the past and never had any problems with the ESC either way.
I just cut the ones off of the Esky ESC and put them on the Exceed ESC, because it was a cheap and readily available fix for me at the time.
Best of Luck and Fly Hard and Have Fun!!!!!
