Did I win?
 

Well I was running my CC neu (2200kv) with my MMM on a track today. Was running strong for at least 15mins and all the temps where fine. 140 on the motor and 120ish on the MMM. My truggy was geared super low ( 8ight 9/48 (36mph on brianG's calc). All of the sudden it just slowed down and stopped. The motor began to just get EXTREMELY hot and had a horrific smell. I unplugged it and saved my MMM/6s. Lets just say it doesn't look pretty.
Would this be under warranty?:lol:

I think you were geared too low. However nice carnage!

Thats really low gearing. The last(only) other ripped CC/neu rotor i saw on RCM was warrantied.

Hmm, I thought it was a little low but not that low.. 36mph with no balooning and lipo at 3.7v per cell.. Aren't you suppose to gear about 40?

6s on a 2200kv motor is a lot of rpm. Also, the low gearing allowed to motor to really spool up.

I would guess Castle will warrenty it; you didn't do anything wrong.

36 is about what I have my RC8T geared for with a 1515 2.5D on 5s, with no figure for tire ballooning as well. I don't think it's to low by any means, when I geared up I actually ran slower times. For me 50/15 or 50/14 seems to be perfect on the track, with 43/10 diffs

I guess issue here is RPM on motor, not actual speed of vehicle.

Well isn't the 2200kv motor made for 6s use? Obviously it isn't ideal because 2200kvx25.2= 55k RPMS. How come they advertise the crap out of the ERBE and FLux running on 6s with the same motor.

wow that's 3 dead rotors within 2 months!!
before that there was none!! oh no!! 3 rotors :lol:

Low gearing may cause heat, but if the system was running decent temps you were not geared too low. These vehicles still place a good load on stuff, even with low gearing. Big tires and lots-o-grip makes load. I would send it in, CC will warranty it.

If they dont I have a real neu 1515 rotor I could sell :)

Hmmm -- time to PANIC! :na:


That makes a failure rate of about 1 in 6500 motors.

We've actually seen a failure rate of about 1 in 2500. Pretty dang good for a 55KRPM+ motor.

Plus, we've watched the failure rate drop by about 70% since we first started making this motor -- we are getting better and better at making the rotors last...

Yeah - - What he said. :mdr:
