The 2000kv option would be best suited for 4s lipo, though I would wait for the 70mm motors to arrive (end of the month), might be pushing it a little bit trying to achieve anything over about 40mph consistantly in an MT with a 60mm long motor.

Would the 2000kv 60mm Medusa run fine on a 5s in an 8th scale buggy conversion. I just ordered one along with a 5s with 16t and 13t pinions. This should be well under the 60,000 rpm limit. Should I have gone with a 1600kv or a 4s isntead?

I am running a 36-60-2000 in my Ofna MBX conversion on 4s and it runs nice and cool, never got above 150. I think you should be fine on 5s, just gear down some.

So this Medusa 36-60 1600 isn't too bad. Put it through its paces last night at the local 1/10 indoor track in my Jammin' X1-CRT geared at 14/46 with 4s Lipo and Holeshot MTRs, through a MM with external caps and CCBEC. Temps after maybe 10mins were under 145 deg. F on both the MM (no fan) and motor, and the battery was maybe 100 deg. I could have ran it longer, but the track was going to close soon and I wanted some track time with my 1/8 buggy.

The 60-2000 ran great. I just wanted to try the Eagletree with the NEU1515 1Y, so I swapped them out.

Well I just checked Medusa's website and they are starting pre-orders of the 36 x 70mm and 80mm motors. I was going to get the 70mm for an e-revo but do you think the 80mm would fit? I know the 70mm would push the e-revo just fine but if I bought an 80mm and got a little lower kv would it run cooler and still have about the same acceleration? I'm not looking for blistering speeds, 45 mph would be plenty but I don't want to have to be worried about anything getting too hot. I plan on running Zippy-R 3s 4800mah 25c batteries with the MMM if v3 fixes the problems.

Thanks for posting that! Had no idea they were going to make any 80mm motors... I just preordered a 36-80-1100 V2 for my 9s1p A123 Savage . Came out to $151, let's hope it's worth it!

What controller are you using with the 9S a123 setup. I am at 6s and really would like to move up to 9s.

Am I correct in assuming that the Medusa 36-80 motors are approximately equivalent in power to a Neu 1521, and the 36-70 to a 1515 motor?

1512 = 61mm long, 1515 = 68.6mm long, 1521 = 83.8mm long

Neus are a larger diameter, and thus can put out more torque. As a quick guess the Medusas probably put out just a slight bit less than the Neus of similar size.
