Brushless system in my E-Maxx running a bit hot, any suggestions?

[Krawlin]

I have a MM/Align 600XL (motor) brushless setup in my E-Maxx. The motor, an Align 600XL, is an inrunner/outrunner hybrid motor, 1650 Kv. I am running a Mamba Max ESC with a Novak 25mm fan and a BEC. My temperatures for the ESC are in the range of 120* to 135*. The motor on the other hand is running at about 140* to 160*. I have lowered the start power to medium and set the timing at 5 on the MM.

This lowered the temps only by maybe 5 degrees at the most. I love the power I am getting, so I don't really want to tone down the settings on the ESC a whole lot. I also have cooling holes in the body.


So, does anyone have any suggestions on how I could cool down the motor? I was thinking about getting a heatsink for it, even though the can is finned, but its a large motor, with a 44mm diameter, and I couldn't find any heatsinks that would fit it.

I was also thinking of some kind of "Ram Air" setup with some kind of large scoop or something for air to go into on the front of the truck, and run a hose from the front of the truck where the scoop or air dam would be and run the hose to the cooling holes in the motor can. I am not sure how well this would work though.

Another fan on the motor might help, but for that I would need to find a Y harness with that looked more like \|/, and I am not really sure how I would go about mounting the fan on the motor or mounting it on a heatsink on the motor.



Any help is appreciated. Thanks.
