It's relative to the amount of pain you can take but 140F for me is too hot even for a second. You really need a thermometer to tell for sure.

A little spit always help to determine temps . If your spit (a drop of water will do too ) boils on the motor then you know the temps are at 212 degrees F or above.

True, I just don't like spitting on my truck.

You are nasty .

So when for sure is the 70MM can Medusa coming out? Have a Truggy that needs a power house

And I didnt see a price in here, any idea on price?

Thanks

212 is to hot. I would say for the motor you want to keep it below 160.

It was 90 out yesterday and I tested a stadium truck out in some uncut grass the ESC was 150 and the motor was 140 after about 5-7 min. I am worried about the ESC I will try again after I cut grass to see what temp is then.

Concerning to hot to the touch. At 140 I could touch for about 1 second. It was not comfortable at all. In hot weather like we are having now I think I would be happy to see 150 on motor after a full battery. I know my 9XL will not last a full pack before it gets to that temp. Hoping the Medusa will do better.

I have the 36 60 1600 V2 on my order. Seems like alot of people went with the 1500, why?

In case you are confused 9xl uis in e-maxx

I think there were some 1500s in stock at a few places, The specs on the 1600 do look better.

I just put my 50-3300 into the 1/10 HPI truggy. It's been raining all night so I know the yard is way too wet for any running this morning, I hope to get some runs on it this afternoon though.

160 wouldn't bother me at all. 180 - 190 would.

Well I'm now also a member on the backorder list for the 36-60-2000. Looking to get a more efficient motor than the 8xl I am currently running on 14 cells (nimh) in my 1/8 buggy.

Will be taking the step to lipo within the next year or so, haven't decided between 4s or 5s but it looks like the 2000 would work for either. Just have to gear appropriately.

got my 36-60-2000 v2 afterbuner today from Impakt..took three days for delivery ...looks and feels real solid...just waiting on cc bec, ....looking for 5mm 32p pinions

going in my 3906

Wow, I must have just missed buying it from them. Went and ordered it direct from Medusa but its going to take 3 weeks.

Does the motor come with a flat spot on the shaft?

The version 2 did not come with any flat spot. I have to grind it on mine but I ended up returning it in favor of the 36-60-2000Kv motor. I'm hoping to receive it next week.

I ran my setup again today after getting a thermometer. Temps were 125-135 esc, 100-105 batteries and 165-175 motor. Ambient temps are 95-98. The thing is I am geared 20/68 now, but yesterday when I was 22/68 the esc shut down. So I don't think gearing the pinion higher is the answer and I don't have anything smaller in pinions right now. The testing was done mostly in thin grass (only slightly thicker than say a golf course). I got to run for about 5-8 minutes until an unforeseen object caught the maxx and busted the rear shock tower. It was still drivable though dragging its butt on the ground.

Do you have air holes in your body? Those temps aren't terrible for the kind of heat your running in, a little air flow might be enough if you dont have some already.
