1/8 buggy mamba max esc overheat ?

you should add an external bec/ubec, and disable the mm's bec by removing/unplugging the red cable. of course you need some good caps and a fan as well. but that's done quickly. I'm pretty sure the main problem is the build in bec, which is simply not made for 4s and therefore it gets very hot. together with a proper gearing that should be working well. for example, an ezrun 150a has a "switching bec", they don't get that hot on 6s.

I always add some extra caps on my esc's, it gives you some extra protection. they compensate peaks in high voltage.

I never had a problem with dirt on my fans, as almost no dirt gets inside the buggy. you plug the fan into the receiver or connect it directly with the ubec. or get a 12v fan and connect it w/ the battery cables.
