4600kv CM36 motor finally gave out - RC-Monster Forums

My CM36/4600kv mamba motor finally blew a bearing, Didn't really blow out, but close enough to make me stop using it. The motor is still solid, but needs a pair of bearings. Does anyone know the size of the bearings for the ols CM36 (not rebuildable) motors? I am thinking of just replacing the bearings, 3+years and the motor still runs good. I am also thinking of replacing the motor and esc (MM) with a MMpro and a 1410/3800kv motor. How long is the line for non warranty replacements for the esc? and is there a non warranty charge for a trade to a CM36 for a 1410 yet?

If you're happy with the 4600 motor (kv-wise), what about getting one of the newer 4600 motors (not CM36)?

+1 my 1406-4600kv was friggin amazing befor it blew out the front bearing. Can't wait for the rebuild kits to come out so I can start running it again.

If i go for the upgrade, it'll be the 3800kv motor, for two reasons. 1. its the biggest setup that's ROAR legal (like i really care, but you never know) for modified class. and 2. I always go for lowest kv i can. I believe using the lowest kv motor possible, adds to the efficiency of the setup. I know in drag racing and most other racing, the need for extreme efficiency is not necessary. I aim to race, when i can this year, with nitro's and need the best efficiency i can find. I am already working on a combo that should be good for an hour+ in race conditions, using a lehner basic xl 1200 motor and a quark 80 esc and anywhere from 3s to 5s lipo's depending on gearing and race length

BTW, this is going into a stadium truck. I know, Good luck finding a race, but they're are still a few racing them

I am not convinced that the 2 poles lehner motors have a better efficiency than the 4 poles neu motors for car applications (high and low load, not constant load).

I'm not too worried about which is better or more efficient, I'm more about the kv of the motor and its effect on efficiency. If i had a Neu/medusa in the same kv range, i might use it
