A couple days ago there was a discussion on speed controllers for fans.
This is a controller I have used for different things which is quite
versatile. It is rated at 25A with peak current of 45A. It includes over
current and thermal protection. Supply power is 6-24v.
This can be controlled with an R/C signal (digital) or a simple pot
(analog) configurable by dip switch; the pot being an obvious choice for
the car. The heating ventilation doors in the project I am working on
will be servo based so I may use the digital feature. There is a 5v
regulated power from the board for tuning with pot or running a
microprocessor (for control).
I actually use dual controllers for this:

This will actually pull a child around in small wagon no problem.
