Mmmmmm. That should go just perfect with my setups. I'm thinking that will be pretty awesome in my hyper 7. Looks like another item I'll have to pre-order.

Bit low for me, I'll hold out for something in 1800-1900kv flavour. Im curious though, all other things being equal, how much more 'power' (torque I guess) would a 4 pole motor generate compared to a 2 pole? Maybe I could just gear up a slower motor, but then I'd worry about my batts maybe.. gah.

The 4 pole will basically in theory make 2 time the torque and you can gear up the lower Kv with 4S lipos.

Not quite 2 times more. It should have the same gross torque per phase but the RMS torque output will be higher because there are 2 times more pulses per revolution.

Yep, till the HV MM shows up

I just soldered up some wires for the Medusa 36-60-2000...
I have it geared at 20/58 in an e-revo and with 4S looks like it'll be around 35-37ish.

What gearing would be a good start for 6S? Speeds show mid 50s with RPM around 45K.

I'd like to use the 2X3S packs I have.. but I don't care to blow another MMM as I did with the NEU 1515 1.5D.

Depends what speed you are looking for with the 6s setup. I'd say aim for 40-45 as a nice speed, the calculator will tell you the required gearing. I doubt the MMM will blow due to using 6s with that particular motor, vs the neu which is alot more amp hungry by comparison.

As for 2pole vs 4pole torque, thats kinda what I figured, just seems a little too straight forward for my cynical mind.

I'm betting with the MMM it will be a little faster.Mine ran 44 with my Quark 80 with 68/24 gears(40 with a MM) 20/58 is just a little lower,in my Emaxx with a MM 20/58 it runs 39.But thats with dirt bonz that don't expand much.So don't be surprised if that gearing gets mid 40's. On 6s I hit 55.7 with 24/68 gears.

Wire my batts in series instead of parallel, but I'd need something in the ~1000kv range then, rather than 1600kv. Too many possibilites...

I just received a 36-60 1600 from Mike today. This will be going into a Jammin' X1-CRT with X1-CR center diff and Mike's CR motor mount. The original plan was to run 6s Lipo geared 12/46, but Mike's mount doesn't allow anything smaller than a 14t pinion to mesh. That means I'll be running 14/46 and 5s Lipo instead. I hope this motor works out!

I'm running a e-revo using fan cooled MM w/ cc bec & two 2s2p 8k SPC Lipos & a single KD 700HO motor on Maximizer beadlocks and Badlands tires. I'm thinking of adding the Medusa 60mm 2000Kv motor and plan to achieve 40-45mph. Is this a good idea or should i use the lower 60mm 1600kv motor instead? Gearing recommendations are welcome if anyone has done this on their e-revo. MMM is not an option right now btw.

I am running 20/56 ( I think) and don't have any issues with temps, but, speed is about 37mph.

JaySki, you running the 60-2000 on the setup below with the same chassis?

Yes.. and it was actually geared at 20/58. thought it was 56.
I just swapped in the NEU 1515 1Y and toasted another V2.. So I am done until the V3s come out.

Sorry to hear that JaySki. I'll wait for the new medusa 70mm cans when they come out. Gotta sell 2 of my relatively new chargers to finance the new motor :)
