So with the help of a handful of racers who gave up there race cars for a few weeks, I sent the buggies to the engineer in South Carolina. I talked to my friend Robin about what I wanted to do. Much shorter motor wires are needed and battery leads fall perfectly on the battery far away from the spur gear. Without the fan behind the motor the esc fits perfect back there. So now we solved the heat problem and added motor longevity from running much cooler.Ī side benefit for some is the much cleaner layout of the electronics. Max timing in the motor, bumping up the radio epa, high output HV lipo’s, boost, timing everything makes heat. In 4wd buggy racing we push these little motors super hard. I just knew with all those cut outs we needed to get the fan over those cut outs to squeeze as much power from the motor without over heating them. How does this take advantage of all the cooling holes in all the present motor designs? It doesn’t.

Most of todays 4wd buggy’s have the fan mounted behind the motor blowing on the end bell.

The Kooler came about by myself seeing a need for better motor cooling I am currently part owner of Crispy Critters Hobby Shop and Raceway located in Fairfield NJ for the past 20 years and a custom RC painter.Īt the track I see tons of over heated motors, broken fans, stupid fan locations and so many other problems that cause over heating.
