    That is not very tall gearing........fans are band aids, for proper gearing, that is pretty warm. What was the air temp?
    Had to be running hard or thru some heavy (tall grass)??
    Would you go flip my truck back over??

    Using the smaller spur will give less rotating mass and transfer more energy to the wheels, their is a big market for pinions so I would get a small assortment of them and use the 54t spur. What were your esc temps? You should aim for them to be about even and significantly lower than 180F. I like to keep my motors around 130 max for bashing, in my mind that gives a 20 degree fudge factor plus the 10 degrees difference or so between inside the can and outside. I don't like going over 160-170 just to keep everything in the safe range.

    3racing also has quite some heatsinks + fans, i'm thinking about ordering one.. Also getting hot temps(topped at 80C on telemetry, had it cool down after) with 18/54 and badlands on 6S but i'm running through loose dirt and grass. Ambient was ~15C. But i can imagine the outerwears disturbs cooling down somewhat.

    Thats your problem. A fan might help some but watch your temps.

    During the Summer months, I run early morning or late evenings. When it is cooler out.
    Would you go flip my truck back over??

    I use a dragonslayer fan from ebay.. It a large heat sink plus the fan. If the fan ever breaks its just a 50mmx50mm 5v fan.
