Here are some pics of the Twister 2.2 ESC we were using these to race with but brushless took over so now we use a $250 ESC in stock class or just to bash with. It is smaller than the receiver even the capacitor they give you with it is bigger than the esc and it has no motor limit and no heat sink just a Small sealed case.
This is my legend stock class car.
This is now my drift car and was my first VTA car sad to say but I did better with this cheap TT-01 Tamiya than I did with my TC5 Team Associated.
