    Recommendation on a good motor fan heatsink

    I'm running only 2s, stock gearing, slipper, esc fan, temps in twenties, and I run it hard threw the grass and motor is super hot after maybe 10-15 min(I don't have a temp gauge but very hot to touch). I even smelled some kind of smoke afterwards but seems motor and esc is ok, I tried after it cooled off.
    I'm thinking I need a really good motor fan heatsink any suggestions.

    Integy make a good single fan setup. The dual fan will overload your bec.

    Yea, I know about the one fan, any links on a good fan.
    I use it with outerwears but a bit of water and slight dirt still gets in, so needs to be durable thanks.

    I've been using the integy one that El Sob mentioned for about a month now. I also run with an outerwears and I've had no problem although I don't run through anything wet. They're only about ten bucks so you're not out a ton if it takes a crap. Honestly, I think the heatsink it's attached to does much more to dissipate heat than the fan will ever do anyway. I run 2s lipos and I've yet to get it over 130ish.

    Yea I do like that but I think Integy or another company makes a more robust type metal grill instead of just the clear plastic fins

    I use a ******* heat sink/fan combo and although the fan didnt last very long it cooled great and it is huge. I have ordered another fan and it should be here next week. I had to do a little dremeling to get it to fit but I enjoy that and its worth it in the end.

    does the fan on that Integy one just plug into the fan plug on the VXL-3S?

    anyone know exactly what mm size the fan is on the Integy heat sink? if I order one I'd like to order a grill to put over it too. looks like maybe 30-40mm?
