I was driving on packed moist sand, concrete covered with sand and some gravel. Lots of powersliding/drifting and hard throttle pulls. 6000mAh 65C lipo. I have ordered alza racing 40mm fan mounts for esc and motor. What fans are these that you are using?
Emulsion
I run the same HW setup and yes, the motor needs fans. I was able to go from a 16t to a 19t pinion and still keep the motor within temp limits when running on medium grass.
I've spent alot of time racing off road carpet trucks(10th scale stadium), and I can say with certainty that an emulsion style shock is more predictable and dependable than a bladder style, in that environment.... With that being said, I will also say that both of those benefits go out the window after more than 5-7 minutes of hard run time, as they do become aerated and can overheat as you mentioned... before kids, I was lucky enough to run an 80s style stepside Chevy on 5 tons and was running 20" travel Knightstalker nitrogen shocks(same as real monster trucks except they run 2 per corner), I wish we could run properly valved, miniature nitrogen shocks with remote reservoirs on these little rigs as that's exactly what they need, but I don't see an affordable version of something like that coming out anytime soon... I've blown 3 bladders on 2 different rc's over the last handful of years bashing, so I have a little bit of hatred for bladder shocks, but I also know the down sides of emulsions, so it's a double edged sword when it comes to bashing, at least for me. Everything is always a compromise when it comes to motorsports of any kind, just have to find what works best for your particular situation I suppose
That is what I dream of!!! But you’re right, the cost would be insane. But wouldn’t it be awesome if we could call Bilstein Motorsports in CA and say, “yo, I want to order a set of high pressure, mono-tube MSP’s with fully threaded bodies, here’s the compression and rebound valving I want…”
So these were what I was running Dan... there is no spring, the main body is filled with your preferred brand and weight shock oil, and at the top of the shock shaft is a stack of washers/valves that determine your compression/rebound characteristics. The resevoir is nitrogen charged and the nitrogen is what supports the weight of the vehicle. For reference, I was running 550/450 frt/back psi of nitrogen. A true nitrogen shock has no spring, therefore, no unwanted rebound effect, it's all handled through shock oil weight and valving. I had about 5k wrapped up in those, and countless hours of trial and error, but once they were set, the truck was awesome! I wish I could figure out how to share a YouTube video on here, I'd love you to see a video of it in action and see how the suspension works! If you go to YouTube, type in "Red Chevy Stepside Perkins mudbog", the video is by an uploaded named Buddy713That is what I dream of!!! But you’re right, the cost would be insane.

And then I’d be on the phone with HyperCoils in the U.K. for the springs. And yes, I’m going linear rate!!
I think those options probably exist in RC Heaven. With free expedited shipping.
20/50 gearing. I have a rocket 35mm aluminium fan currently sitting in my max6. Now I'm in the process of switching to 40mm ESC fan and adding one to the motor ( I already ordered fan mounts ) after I ecountered this overheating issue. I'm having trouble picking the right fans tho, I was thinking about these: https://pl.aliexpress.com/item/1005....0.0.74e6VKMsVKMsI2&mp=1&gatewayAdapt=glo2pol
Your English is very good!20/50 gearing. I have a rocket 35mm aluminium fan currently sitting in my max6.

Can I plug them directly into the receiver or do I need to get 3s lipo to power them. And which version should I pick 5v or 12v? As for the shockcaps... No side to side play. I think I may have damaged the o-rings by tightening the shockcaps too much during a first assembly. I'm going to replace them, hopefully they will have this size o-rings in a local shop. I also had troubles with a bleeder screws leaking, applied some tefon tape, no issues so far. Sorry, it takes me ages to write anything in english

I picked up the o-rings today, they appear to have better snug fit. They are 2,5mm thick whilst the m2c ones are 2mm.Your English is very good!
I have the same frustration with the small bleeder screws, they should have included Delrin washers like HR does. My leaking does appear to be coming from the O-ring area, will get a photo later. Difficult to measure the O-ring but they seem too small to me and the cap lip edge are very narrow.
Is there a big difference in rpm's running them on 7,4V instead of 12V? It seems that a 40mm server fans have a 4mm mounting holes, do I need some type of grommets to mount them? ( Fan mounts have a 3mm mounting holes )
Well... nevermind, they are still leaking even more now with the new o-rings. I'm unable to tighten down the shock cap enough, because the o-ring falls out of its place, straight into the oil. I guess you must use a flat type of o-ring, you can't replace it with the round one. Given the comments above I changed my shock caps back to a stock, bladder type caps. I'm sick of the m2c ones ( a.k.a the biggest piece of dog sh.. ).
my o-rings have not come yet but they are the same style. Looks like I will be disappointed as well.
As I said before, i may have damaged them. Maybe I will try to rebuild the shocks with m2c caps in the near future, using a fresh o-rings. M2c parts aren't available in my country so 10$+ shipping. I'm sticking with the stockers for now.
