Definitely not gearing, you are geared for ~45mph, Voltron geared for ~60mph.
Your heat issue is somewhere else. A T8 esc should shut down(thermal) way before that temp of 240F. Mine thermals around 180 degreesF. Something is not right there.
Hope you're not using any software timing. These 1/8th heavy cars do not like much if any timing. That's one reason why Tekin T8's runs in dual mode(sensored to sensoreless)No Booost or Turbo to heat thing up.
Make sure the car coasts easily. Take off pinion/motor and give it a coast test. It should roll easily. All gear meshes should be smooth. Voltran's car is super smooth and quite. He goes 58mph on the straight.
I would guess with the T8 esc not thermalling is your problem source.
And yeh those YEH Racing 30x30 2S fans are money.
I'm getting somewhat interested in this car especially if Voltran gets any faster, lol. It's a little hard to get fired up now because our outdoor season just ended. I'd really like to see pivot ball suspensions front and rear which adds adjustability. Hopefully V2.
Desoto was untouchable at our big GLC race this year with his nitro version.

Fastest on-Road driver i've seen, Dominates Electric Touring and GT8 at our track. He's all ways running fast as hell and his cars are always dialed.

I forgot to mention his mouth is as quick as his cars
Me and Leah goig to head down there in a lil while. Suppose to get sunny and 71. Hopefully it dries up by then.

I just took it out for a run in front of my house. I ran it pretty hard for about 10 minutes. I checked the motor temp at the 10 min mark and I got an astounding reading of 259 degrees! Also it was far from silent. There is a pretty aggressive pitch to the sound when running wide open.

Never had this problem when motor was in the RC8.2e. Never got hot.
Just checked and my gear mesh has some slop. Motor mount is so tight on this thing it is had to gradually move the pinion in/out.

Thought we were talking about esc heating up? Is esc temp ok now?
Fan(s) should keep motor temp under control. Voltron has a good dual set up on his motor(pic posted). I have seen Tekin motors approaching 300. Motors will be short lived much above 180. Get some air flow also. I have 2 ducts from the windshield, one to the esc and one to the motor. Maybe some grill cut outs or brake ducts for the Snake just like the real race cars. These heavy cars really heat up things if you drive hard and use push brake. My esc will still thermal if I'm too hard on the brakes. Make sure zero or very little drag brake. Limit max braking in software or better yet at Tx braking end point. Using Tx end point allows you to dial in max brake on the track. I never have tires lock up under braking. My Kyosho GT2 conversion has mechanical brakes so no braking/heat issues there. Some have added mechanical brakes just for that reason.
Track temp also may require different gearing. When track temps are 130-150 I use a shorter gear.
I would zero out the timing. Doubt if you'd notice any performance change.
Are you sure your temp checker is accurate? I have seen those cheap ones way off. I have had some. Spit on finger placed on motor would instantly boil off at that temp. That's the method we used back in the day. Spit should slowly disappear.
10 minutes is way more than I can run hard using 6800 70C 4S lipos. Which tends to confirm your shorter gearing.
These cars can be frustrating about heat issues. I have had several heat issues and have spent hours/days sorting things out. I am lucky that I live very close to a great track where I can test. All members get a key.

Is this an offroad used motor? It is cleaned out with good bearings? Just a last thought.

About 81, so not hot at all. Maybe it is the motor itself as it seemed to behave like the gears were slipping from time to time when it would start moving. It would almost stutter. It was different than the cogging I experience on my Castle setups. Sensor cable was in.

Look/listen to Border r/c video above. That sounds about right.

hi,
thanks,
i did use the plastic molded spur sound much better then the steel.
temp of the motor is around 85C top speed till now is 87 Km p/hour runtime around 14min.
next step is a other body then PF* i have my Lambo almost ready much lower and more steering show here a.s.a.p when i finished it,
esc just all the setting stock as it came in box no time too adjust it yet

bhodi11 just curious what was the outside temp when you did your 10 min run?
And are you ripping up and down your street full throttle or are u at a track?
