I think I just have to build two type of speed controller. alright continue with the MOSFET schematics. Anyone know any power mosfet that is more powerful then irf1404 in that kind of size. Orgonom? you know how to design a MOSFET schematics? Is it recommended to use ICs one the diagram? Hope there is no IC needed in the diagram.

And also JasonL, I'll wait for your schematics. This MOSFET speed controller is just for track racing. I'll put your design on my Tamiya QD with modified 15t motor....

I have found diy RC speed controllers on the web when I was
looking- suspect they are still around

how are you going to translate the pulse width to varing resistance/voltage?
