Hello Tony. Regarding your fan setup pictured in the last page or two, do you get a better cooling effect just by glueing the fan to the chassis blowing on the motor as opposed to using a fan attached to a motor heatsink?
And on the topic of diff grease/oil, what viscosity grading system are you using? I've got a couple of u-pro gear diff's now, just running the rear straight out of the packet and I know I have to change the oil in the front for a stiffer action. 120K(?) i see is the go..
Cheers.

Fans. I don't like the concept of heatsink fans. I realize that it's an easy way to mount a fan to any motor, but I think that the extra heatsink just traps the heat in the motor and doesn't allow it to dissipate like it should. Besides being bulky and ugly to look at, most heatsinks that I've seen run the fins in the wrong direction. To be effective the fins should run length wise along the chassis, not parallel to the motor (on a belt drive car). As the heat tries to escape the fins, the longitudinal design would allow airflow to "clean" the hot air off of the heatsink. I hope that makes sense. I haven't run a heatsink fan to compare temps, mainly because they look terrible. (I'm vain). With the BOSS fan glued to the chassis, like I have it, the motor runs 30-40 degrees cooler. Last night I hardwired a BOSS fan to the ESC instead of plugging it into the receiver and it puts out some major airflow. With the car on the table, I could feel the breeze coming from the fan. Good luck with your choices. Best of luck on the track.

That makes perfect sense Tony. I hate clamp style heatsinks, and have for years for that very reason.
Applying that same logic, the current location of your fan would just recycle hot air coming off the motor back onto the motor through the fan. Optimal fan position for you would be in front, or front/top of the motor.
I went through the same issues with my car, and found the side of the motor out of the flow of air under the body was best. It allowed the same amount of cooling on receiver voltage VS battery voltage with the fan blocking the underbody airstream.
Our motors are positioned differently though, so that changes things a little. That would put your fan on the endbell of your motor, and would be quite useless hitting so little motor metal.

Hi Guys
what is optional 1.25mm camber plates for?
Is that giving a longer camber link option with more inside hole or what?
also do you guys using alloy turnbuckles?
Thanx

I have often thought of making a fiberglas/FRP duct that intakes cool air from the front of the car, encloses the motor can, and use a high speed fan to exhaust the hot air. Lack of time and motivation netted a lexan mount instead.
Since the air under a TC body is likely turbulent at best, fan position isnt crucial. But there are always ways to make things more efficient...
