Castle 2200Kv or Medusa 80mm 2000Kv

[E-Revonut]

I got a reply from Mike today. He has recomended the 70mm so that's what I'm gonna go with. He was running the 60-2000 in his but said that at the end of a 20 minute run he was at the high end of the safe temp zone. I have seen Mike race and as he said he is a very smooth driver and if he was on the edge I don't want to chance it. For helping to control wheelies he has recomended playing with the settings on the controller and my radio, specifically the throttle curve. Hopefully I be placing my order before the end of the week!!!

I'll second that, the 60mm isn't any good for racing.. I toasted one and I'm not a "bad" driver.. you need it geared really low to keep under temp in long mains. Holds up fine for a 3-5minute heat though. I'd say 70mm is the bottom of the scale, but you can snag Castle 2200kv motors for 150 why would you bother with the medusa? PS check the specs, the medusa 80mm will run hotter than the castle-neu, it cannot generate anywhere near as much torque.

I don't want the CC/Neu because it's a 2200kv motor! I'm running 5s and I don't want to gear down that much. Lower kv higher Voltage geared for the same speed is a more efficient setup. Also a small pinion and large spur that would be needed for the 2200kv on 5s isn't as efficient either. The closer the two gears are to the same size the less resistance there will be between the gears. My 1515 2.5D is 1650kv and I'm very happy with it, a little less power wouldn't be bad. A 1600kv Medusa is the closest I can get to this without shelling out another $260. I already have a 36-50-4800 in my crt.5 and the motor is awesome, I expect larger motors will be of the same quality.

I don't own any 1/8 scale motors yet BUT I feel the same way you do.

On paper 2200kv is too much, especially since I plan on running 6s. If CC/Neu offered a 1600kv or thereabouts then I think it'd be a stronger argument. But as it stands, on paper, the 1600kv Medusa seems like a much better fit for 6s.

I tried running my 1515 2.5D on 6s and quickly switched to 5s! On 6s even at 3/4 throttle I still couldn't give it everything cause it's flip over backwards! 5s is much more driveable IMO for this motor. I'm planning on running the 36-70-1600, MMM, 23t pinion and I have 54,56,58,62,65,+68t spurs to get the speed for a particular track or bashing. I also have a 20t and 25t pinions already.

Well I agree about the 5s, just make sure you can run it racing... many tracks won't allow over 4s hardshell. If it's open though and doesn't matter and you want to stick w/ 5s price wise you can't find a better option than the medusa 70 or 80mm. I would get the 70mm if you only want 40mph, if you want 50+ I'd say get the 80mm can.

To your point also.. I have a Neu 2.5d on 5s in my Losi 8ight-t conversion and it's perfect on the track :) I have the Medusa 36-60-2000 in my 8ight buggy and that too is a perfect home for it, the motor again wasn't quite enough for the truggy or erevo but is sweet on the buggy.

Good luck.
