I had I chance to add 4 caps on the MM in my Ofna MBX basher. I don't think the MBX was ever intended to have this much power. It really doesn't handle all that well compared to others, but it makes a great basher. It's set up with 10L, MM, 4s Flight power 3700mah.

I made a 4-pack of caps. Strategically placed them so all the negative wires faced the middle and then ran the positive wires along the out side. Used some tape to hold them in place and shoe goo'd them togeter. Soldier them up and added some shrink tubing.

Maybe its my imagination but the caps seemed to make it punchier. I never had problems with heat at the ESC but the temp was an ice cold 100* with fan attached. I think the ESC is running cooler by about 10-15*. Here are some pics. I can't wait to add caps to my Quark controllers.
