Hey Richy! How's that stuff treating you? In regards to the rims, they are from Wild-Z racing, apprently a Japan company as that's where they shipped from. There was a little bit of a wait to have the requested offsets made. Here is the place.

pins, this particular brushless system is made for Losti Micro-T's. I've seen them on ebay for like $50. However, I advise not to go for this brushless setup. It doesn't have enough torque--to little power.
The brushed motors I had were way crazier than this BL system.
