I got the Surpass motor in with a 16t pinion and drove it a couple of times.
Boy is that motor fast!
According to the spec sheet it puts out as much power on 4s as the stock Kuron does on 6s. I have no reason to doubt that.
It's awesome to see this little buggy fly over my usual beach bash spot.
As specified, it is quite an Amp hog.
The Torox185 struggles with it and is getting hot. Now, should i gear down or should I shove a Max6 in there? 🤔

I found out that the right rear set screw was glued solid in the stub axle from the factory. It was a PITA to remove. I tried screw extractors. No result. I tried to drill the set screw out and got nothing but overheated drill bits.
In the end i got the hex pin out with my chain breaker kit. The stub axle was scrap now and i replaced it with a spare spring steel one.
A couple of days later i had the same problem on the front of one of my Asugas. Again the chain breaker came to the rescue. This CVD stub couldn't be saved either. Luckily i had a complete CVD drive shaft and one cup from the new upgrade kits as spares left.

I vote bigger esc over gearing down, I'm an advocate for overkill on esc's, they never fail to deliver what you want and no real concern of them going up in smoke

I like how you are thinking.
That is my thought too. I am postponing that for now, though. I spent a small fortune the in last couple of weeks already. I will be easy on the throttle for now and see how it holds up.
 
Max6 is a bit overkill if only going to be running 4s, could upgrade fan on esc might help a little bit but if only plan on running it in 4s I would consider the Hobbywing xerun esc basically race spec esc either the xr8 pro (4s) or xr8 plus (4s-6s) both 200a and not as big or going to add as much weight to rc as a max6, xr8 pro similar price to max6 the xr8 plus bit more expensive. Or if really want to have a lot of headroom as far as amps are concerned I’ve been looking at the mad components max8 esc 3-8s 300amps & similar price & size to max6.

Unfortunately the XR series are not waterproof. I can't take the risk of getting them wet. How about the Max8 g2s?

The torox185 is a rebranded Hobbywing max8. The esc is handling the amp draw just getting too hot I would just put a 30mm fan on it see how goes. Just disconnect fan installed and slap 30mm fan on top. Screw holes line up for it.

I am pretty sure adding fans to electronics under a body that traps heat like a buggy body does, only results in moving hot air around. So i did to the Spark body what i already did to my Asugas:

I also ordered some of these:

That’ll do it with current heatwave think a lot struggling with temps atm. But a few nice buggy’s with similar cooling cut outs. Love the little sun visor on this Syncro

This is a great idea , when I recently had to clean a stone out of my ESC fan I did think it was a touch on the small side
 
Some parts from Jennys arrived this week.
Complete Spark suspension to put on my Radix and a drive shaft set as spares, since i am pretty sure they are the same as the Radix's.
I fitted the steering stiffener on the Radix, and i noticed i had to reduce droop to prevent the stiffener from touching the upper arm.

The Spark arms have a cut out for that.

Could you just Dremel a bit out of the arm?

I could, but the Spark arms are much beefier. They are 1.5 mm thicker and much wider.
I will put them on asap, but we spend a lot of time at the lake now, since it's summer break for the kids.

Does anyone know if the ADU suspension mounts for the Spark will fit the Radix?

Yes if you mean the hinge pin holders/abcd blocks. Have them fitted on mine with spark arms
