First upgrade;
GRP S7 slicks and skid plates. Links are at the bottom.
Skid plates are a must have in my area. GRP S7 here in FL, asphalt ambient is ~ 110F in the morning. I'll go to S5 during winter time.
Main goal is bashing.

Next on the list, the stock motor fan died on me.
Upgraded to my new 'go-to' fan as it fits in the 35mm envelope that seems to be so popular and brings along many limitations.
My stock fans, on stock gearing worked just fine for standard bashing.

My selection doubles the CFM on the standard 7V BEC voltage and easily triple/quadruples on the rated 12V. Going forward, planning on placing 2 of them in series and connecting them to the battery leads (24V aka 6S)

Re-utilized the standard dust/debris cover on the ESC, all you need is longer screws.

Note that the standard cover does not reach the bottom, only used as a screen.

You only need to connect 2 wires (+ $ -) , I trimmed the other 2 for RPM control. this ensure they will run on highest possible speed.
More on the fans, I've added nut and spacers both on top and bottom for the motor fan. ESC seems ok even on 12V.
Motor fan required standoffs on the bottom to ensure air flow, else the fan will fight itself. Short standoff on top (nuts) just to ensure that my filter will nt get sucked in. In addition, I already had 1 leave blocking the major surface and standoffs ensure side intake as well in those conditions. This comes in handy during fall :ROFLMAO:

my stock fan took a poop on day 1, I see that this fan comes with 4 wires, you stated you cut out 2 wires? which two do you keep and connect to the esc? I'm new to this but I don't want to fiddlestick it up. I ordered a damn 30 mm fan and it doesn't screw to the aroma heatsink, rookie mistake enemy part I later saw that the stock fan is a 35mm. and there isn't many that size that fit the stock heatsink. any help is greatly appreciated.
 
Call Horizon and they will send you a new fan under warranty.

No, the fans I list run on 12V and there is more to it. They will not run on stock voltages. They will kick in at around 7-8V.
If you have a 4 wire fan, typically the red and black are pos/neg. The other 2 are for speed control. Don't clip them too short, I always leave an inch or so.
I do run them of the ESC but they need a 12V up-converter or you could connect them to the balance plug of the lipo. If all this sounds unfamiliar I wouldn't recommend taking that route. You will need basic soldering skills and additional connectors.

Wow...good read this is all good and would love to add 12V fans but none of this sounds familiar or close to knowing how to do this....sure the added air helps!

hey, thank you for the write up. I have couple fans similar to the ones you mentioned. I have the skills and parts to solder, or make connectors but I'm not familiar with what component you used to hook it to the ESC, and the link you provided has expired. If you connect them to the balance leads can you put more than one fan on a balance plug? I saw you said don't wire them in series, is the only solution to use the buck converter or is there another way you can wire them? Sorry, I'm not very good at electrical components and what to wire where, but I do have the ability, parts and tools to put electrical components together. Thanks for the write up and your help
 
@rdskns75 For a stock replacement fan I would go with a 30mm alu fan. Similar to link below, note that they come under many names but are all from the same manufacturer, buy the cheapest. Rcjuice.com has them on sale every couple month for ~ $10. These plug into the ESC fan plug.

If you have a 3S lipo or any higher lipo you could utilize the balance plug, but you will need 12V fans. You can run as many as you want up top ~ 3A load. A typical fan is anywhere from 0.5 to 1A i.e. 3 fans are possible without thinking You typically only need 1 for the motor and 1 for the ESC. More doesn't make sense, but it looks cool but isn't in reality.

I do not like that route and have 36S etc. I soldered wires directly to the battery connector and used an external BEC to regulate to 12V. Makes my life easier.

Don't do this for off road bashing. The fans will not hold up well to jumping. I typically break a couple a season on my on-road just by hitting stuff :)
Keep that in mind. Hence, I dislike the high $$$ fans for that reason, nothing will last.
