Cheap upgrade for old Tamiya cars that use the old mechanical speed control. Didn't want brushless, so this is ideal. ESC works as advertised and easy as to setup. Using with TL01 rally car, 19t pinion and 13t motor. A lot of fun. I put a fan over mine just to be safe. BEC good too. It uses jumpers for different batteries, fwd, brk, rvs etc. Very happy.Thanks RCmart.
