Isn't Paul Ratajczak using a set of motors similar to these on his T048 T-34 tank? Are his brushed or brushless?

My goal here is to have proportional speed control foward and reverse with an home made interface(to connect to a C6C) to the motor that already have the speed control intgrated in it... that would be an inexpensive solution!On 3/13/07, Frank Pittelli < frank-at-rctankcombat.com> wrote:Philippe Lachapelle wrote:

That's an excellent motor, but you can *not* reverse them simply by
changing the polarity of the power leads. As someone else pointed out,
that will fry the built-in electronics. The phrase "can be simply
re-wired to run clockwise" probably means you can easily take the case
apart and re-arrange the internal parts to cause it to rotate in the
other direction.
You'll need some sort of mechanical transmission if you want reverse.
