Remember the topic that got confusing after a while regarding the Hacker car ESC's and Jeti's.
I went out and bought me a Hacker car sport. Received and opened it up today. I am surprise to see that there are 3 single sided power boards, whereas the mamba has 1 dual sided powerboard. The caps are rated at 50V@330uf. I counted a total of 54 fets(each layer having 18 fets). The heat is tranferred through some thin thermal tape between the boards. I have yet to run it and see how well it does.
