If you can always cut it with a lathe...However you said it had poor performance before you cleaned it out..Just looking at your first pic's of the com and some of the wires look fried..might be very wrong but if the insolation is sizzled it will never run right..send it back to HH if it is...Hope that helps... |

So you're thinking I may need a new armature? I'm about to post up in the JRH CS thread, get the man himself's opinion on it too. Thanks. |

Your best bet is to get a hold of JRH through PM or post this in his motor help thread in the vendor section. Yes your com looks to need cut. Can't tell on your brushes because they are still in the hood. Looks like your timing is off and it is arching bad. JRH in 3..2..1..

That's what I've read, anyways. I'm going to do that to my new motor but I'm going to stick it in a cup of rubbing alcohol first. | |

Here is some helpful information for those who want to cut their own Commutator. Fist off here is a link to my electrical page. http://www.team3sixrc.com/rcelectronics101.htm second is a little walk through on cutting a comm http://www.rcracingusa.net/commcutting.htm next is a few lathes you can purchase. You can get the Integy which for it being Integy isnt a bad cheapo. the only issue is its not the greatest lathe http://www3.towerhobbies.com/cgi-bin...?&I=LXLBB7&P=7 But you want to invest in something like Hudy http://www.hudy.net/xhudy/products/p...98cb89d86c96c3 or Much more http://www.redrc.net/2007/11/much-more-commu-lathe-2/ I say that because having a good true diamond tiped lathe is the key to a good comm BTW, you awlays replace your brushes after you cut the Comm. In the long run, if your motors are expensive or you know how to cheat your motors to make them preform more efficiantly then its a good lesson to learn and an a good investment. But if its a cheapo motor that isnt hand wound or whatever the case may be. just purchase a new motor. Im sure John takes used motors. |

If I get a chance to check tomorrow, and everything looks good, you can send it to me for a cut. I am going to try to cut mine. | |

Very cool of you, thanks! After speaking w/JRH, I decided to send it his direction so he could give it a once over.

I might just throw the motor in some distilled water though, just to be safe. | |

Got an email from jrh a couple days ago, comm is cut, brushes replaced, new endbell, bearings, already broken in and should arrive today with a Torquemaster ESC and CC BEC. One week turnaround since I shipped. |

My Cobra comm lathe won't cut a puller arm but I would cut a comm that looked like yours and throw on new bushes it would be better than new.
