Having three fans in his car is not a function of the stuff not working without it. Having three fans in his car is a result of a few things. The first of which is wanting to make sure that he gets the best performance out of his equipment in very high load situations for the full five minutes. The second is the fact that when your car is underweight, you might as well add weight that will actually benefit you somehow, instead of just sticking a lump of lead in a random spot.

Cooler equals more efficient and consistant in the realm of electronics. If you were trying to win a race against the very best in the world wouldn't you want your car to be as efficient and consistant as possible?
I have been waiting for someone to post this...

I woulda but couldn't come up with the rite words...

well spoken Evicerator..

I have been running fans for over two years on my equipment and it has been working wonders. At the end of my run when geared correctly, I was still doing the same lap times as when I had started my run.

Do you blow air at the motor or the speedo?
My Novak TC2 runs soooo cooool there is never a need to cool it no even when I'm running sub 10T motors.
The GTX is rated to be lower resistance than the TC2 or any other Novak, so why the need to blow it cool? Is it really hot or is it just there to make up some weight?

If you read Steve's post, the cooler things are, the better. It's not a matter of it over heaing without it. They were probably a little under weight and figured functional weight that help keep things even cooler would be the best way to make weight.

i didn't say that i like kinwald's because it's loaded with fans....


i just said that this car is probably the kinwald's car because he usually put fans everywhere on his cars.......


but i don't think using fans is something to worry about the quality of the products.....

i don't use fans to blow my esc, but i do use to keep the motor endbell as cooler as possible.....the motor keeps its performance, no fading, no burnt brushes.......

Reedy makes replacement fans for their heatsink/fan combo. $9.99, part number: 448.

You can also find them at computer/electronics supply places. I'm not sure of the voltage on the fans. I've used 5v fans as well as 12v fans in the past. My receiver's BEC puts out 5v, so it's a good match with the 5v fans. The 12v fans don't get enough juice to blow at full power, so...

I paid more than $9.99 for my fans by the time shipping was figured in, so you can make your own decision on that one.

I wouldn't recommend going smaller than 25mm x 25mm... anything less than that and the CFM just isn't good enough to do anything....

indeed.....

this 35mm fan was used on a xray (installed like Jilles Groskamp and Greg Hodapp do)....

but I think on shaft cars a 40 or 45mm will be nice....

Default Fans

We mounted a 1" sq, (25mm) fan on the nerf wings of our TC3's, 5 v fans, 1.8 cfm (be sure to ck this because there are some out there that cost less, but only put out about half the air (cfm). Dropped the motor temp about 30 deg, same gearing, just helped the motor brush to live longer, and be as good at the end as it was at the start. Jameco Electronics.
