those new escs and motors are from okhobby.com. he is just buying them and marking the price up. i was thinking about getting the 160a esc and the 4 pole buggy motor from okhobby. it comes out to $107 shipped.
They say a good mechanic only needs 2 tools - WD40 & Duct tape. If it moves, and its not supposed to, duct tape. If it doesn't move, and its supposed to, WD40.
