I have had 0 issues running my 60-2000 on 5 and 6s in my Erevo.Actually even with the same gearing it seems to run cooler on 5s then 4s.Perhaps the longer rotor could make you want to turn lower RPM's,but really the 37000 seems to be in the sweet spot for mine.

It probably runs cooler due to not be full throttle as much.

I would select the 2000kv for running on 6S. You'd still be within the operational limits of the motor, and I find that Medusas' sweet spot is between 35k and 45k rpm, at least thats when my 36-50-3300 really becomes lively. Also, when you're running 6S the current draw is less and as a result everything runs cooler anyway, same reason why you see a difference between 5S and 4S too; if you're pulling the same amount of wattage from both setups, the 5S setup will obviously have a lower current.

Nice, thanks for the inputs guys. 36-80 2000kv on 5S (6S later)it is! I can't wait. I really hope to have everything by next monday. 60+mph truggy baby!!!

I'm such a noob, lol.

I on the other hand am still undecided...

I wanted to know what gearing you guys would recommend. I've ordered a 3680 1600kv (

but the order has been delayed

) and plan to run 6s in a 3905. Still the stock spur so what pinion do i start with?

With the 80mm you could actually go to Mod1 Revo gearing as long as you get the spacing right. A 30T pinion and 54T spur should give you around 65 MPH but that's a huge pinion.

Would I need to run a huge pinion?

If you keep the 32p gears, yes. What is the minimum distance between the motor shaft and the input shaft? If you can get that measurement you can use BrianG's gear diameter calc to figure out what Mod1 gears you can fit. You could use a smaller pinion with a Jato spur if you wanted, but you'll get more speed and tougher gears with Mod1.

Where can I get heat sink for a medusa 36-60-2000?

You'll want the "L" clamp.

Or there's the Novak 5412. That's what I use on both my motors. It's got fins big enough to mount fans on.

It doesn't have a clamp on it though, MedUsa motors don't have their endbells screwed in and can possibly come loose after a hard enough hit.

Never happened to mine while it was in the rustler, and I broke that thing so many times I had to convert it to FLM. But either way, his choice.

I'll be running a 70mm 2000kv in my E-Revo and running MOD1 gearing, so what you guys are saying is that it may not fit due to the spur/pinion gap? If thats the case then I'll look up a 40t spur and a little bit bigger pinion (I'm going to be running 4s and gearing for 40mph).
