Sweet!! It's gonna rip with that combo! As for the fan, both my stock torox are holding up fine. I blow everything out with air fairly regularly try not to blow directly at the fans, I blow through the side vents of the esc cover. Too many rpm from an air hose will destroy the fan.Also, I check the fans to make sure they're spinning whenever I turn a rig on and off. Usually if you catch it soon enough you can remove debris and keep them going. They're very fragile, once something gets caught and prevents a fan from spinning for any real length of time it's toast.
Are you looking to put a fan outside the shroud or under where the stock is mounted?
IIRC the fan under (stock) is a 30 x 10 mm. I buy them off amazon 5 for $15. They don't have the right plug but I save plugs from dead fans, servos, ect just for that purpose. Then solder them to the new fans.
I have bought the more expensive aluminum frame, high rpm fans such as rocket but IMO they're just as fragile as the cheap stock plastic ones. For me, it's usually debris that either breaks a blade or prevents the fans from spinning that causes failures. Hard to tell it's not spinning when you're busy having a good time running your rig I find😎
Also I should mention that I tend to run pretty conservative with regards to gearing and such, it's just safer that way since my electronics are not running at their limits all the time. If a fan goes out in use, sure it gets hot but not likely to failure. Sorry for the long wind, I hope there's something in this that helps. Enjoy that Sketer!!😁🍻

Thanks buddy. Will run 4s only. Got some margine in temp then. I will leave the fan on ESC as it is then and keep an eye out of it runs properly. Got a flexible cover that i will put on so there is less change of stuff getting in. Happened with the 135 ESC and that sucks. Luckely i found out quick and was be able to get it out. Will keep you guys updated in my own stig Sketer threat.

Thanks. Not have a 3d printer......yet. i ordered this 1 for the motor. Was wondering what king of fan peeps got on there ESC.

I commend you for your efforts, but that design covers too much of the surface area of the motor that is normally available for heat dissipation. Mounts like the one in the link below are popular for use with motors that have fins on the can because they leave most all of the surface area clear.

it covers hardly any of the surface area of the motor, just the part where the cable ties go. I copied Corally's design but increased the fan to 40mm

Just a heads up: putting a heat sink on a motor with a finned can doesn't cool the motor as it should. The reason is that the heat sink sits on top of the fins and doesn't contact much of the surface area of the can. A fan holder like the one in the first link below is a better choice for motors with finned cans. You can even use two fans with one of these mounts (second link).

Thanks for the tip. Gonna try my setup first because i ordered it allready. I can always change it when it does not work 😉

I believe the fins on a motor (if it has them) are the heat sink. In which case just a fan (and mount) is needed. Personally, I always run a rig before adding fans since some don't actually need them. Out of 8 rigs I currently run, 4 have motor fans, 4 do not since they never get hot enough to need them. Ideally, I try to avoid them, but some setups just run too hot.
I've had pretty good luck just using M3 x 25/30mm screws through the fan frame secured with nylon insert nuts on the backside and cable ties around the fan and motor. The screws are basically used as standoffs for the fans. Holding them off the can.
Another thing to consider is that an added heat sink can give inaccurate temperature readings if it's not making good contact with the motor can. It should be tight enough that it doesn't move on the can without a considerable amount of force. If it keeps moving around during use, it's probably not doing it's job effectively.
Edit: Did I mention I hate these fans!? LOL..it's probably quite obvious I suppose?

This is how I mount a fan on my Radix6. The fan in the Radix is situated in this manner because the body is so low at this point that the fan can't be on top of the motor or even mounted on an angle. Corally offers a 40mm fan mount that attaches the fan to the chassis in the same position as I have mine installed.

https://rchobbyexplosion.com/team-corally-fan-holder-for-40mm-fans-1-8-c-00180-224/

I use fans primarily as a safety measure in really hot weather: as the old saying goes, "It's better to have and not need than it is to need and not have".

My Castle 1717 1650 does not need a fan: even when I ran it hard in upper eighty degree temps for 20 minutes at nearly full throttle, I could never get the motor temp above 120 degrees. The Traxxas 2200kv motor in my Maxx doesn't get hot without a fan either.

I will run without a fan on the motor first. If that works i won't install it. It is obverpowered anyways then on 4s so it should not heat up much i hope. On the Kuron 135 with a corally fan mount it heated up. I changed it. Worked better. I am not a expert. I just learned from experience.
Thanks for all the help and advise. Much appriciated

Yes, funny how some need a fan, others don't. My old Thunder Tiger MT4-G3 has a top cover that basically encloses the whole chassis once installed. The stock motor, and the HW motor I replaced it with always ran hot. There was literally no room for a fan under the cover. I just ran it for short periods after burning up the stock motor. Just the way it was.. now that truck has a Corally combo in it, full pack on a 90 degree day, no issues..weird. All 3 motors were pretty much the same, 4274 2000kv, 4s. The only real change was from a 6.5" MT tire to 5.5" Truggy tires but I did increase the pinion from 12t to 14t..

My brother has the Traxxas sludge, runs cool as can be bone stock on 6s with no fan. E Revo 2.0, hot as a pistol, bone stock. Actually Just cooked the stock motor in it about a month ago.. Has fans now :LOL:

Conclusion. Belted tires burn motors. That's why i upgrade my motor instead of my tires. Will go back 2 belted when upgraded. Does that make any sense? 🤣

To some degree, yes. Belted tires are heavier, but gearing down to reduce the load on the electronics can make up for it. I've never owned any belted tires myself, I'm too slow to need them. Also, they tend to be much stiffer than unbelted making them less than ideal for off road use.
 
Is there any aftermarket part available to mount my on/off switch from my torox 185 to my tower to tower brace from my sketer? I sticky taped it to the place where my old on/off switch was and it came lose 😔 a link to a european shop would be nice.

Idk, but it is the same switch as the HW Max esc's..they're quite popular so maybe?
