Something up with Mamba Max?

I would add a 40mm fan on the MM. I am running 39mph with great success on my emaxx. The fan makes a huge difference in temps for me. The 40mm fan doesn fit very nicely but it rests over the caps and the heatsink. I use 1 screw to keep it in place which makes for a flimpsy install, but it works. My temps on the MM dont go over 126 degrees in 100 degree days vs I was getting 150 ish range with no fan on 80 degree days.

I dont think the fan is an end all solution though a truggy is too heavy for an MM at 45mph.

If you want a nice clean install, the novak 25mm fan fits perfectly over the heatsink and you can screw it right into the heatsink and its very secure. You can use 4 screws right into the heatsink and its solid.

I think you are a bit overgeared too. Shoot for 40mph and you should be ok. As everyone has said you wont notice a big difference in top end and the MM will be happier.

Punch control also helps to get the amp peaks down so adding some will help with temps. People have had differing results but for me 100% punch control dropped temps by a bunch.

You can play around with motor timing, maybe use low if you are not there now, that will help with temps too. I have read though that the feigaos like a bit of forward timing and they are more efficient like this, but its something to consider.
