Yep. If the motor starts getting hot, give it a rest. If it throws sparks then the timing needs to be reset.

Hey John,
What brushes would you recommend for replacements in the HHH motors?
Both the 2.2 and Super are long over due..

Thanks

Any reedy style laydown will work. HIgh silver brushes can use lighter springs for better wear. Copper brushes are cheaper and wear longer.

Hey John bring your motor's down to the shop i can cut the com for you and i have the laydown style brushes there at least I think I do. I'll make sure and let you know on the brushes. on second thought you probably have a com lathe don't you or you could even use your tt lathe

Question for ya John: Just broke in a new motor's brushes in water for a few minutes. I noticed in reverse there's no sparks but some in forward, the faster it spins the more sparks. Is this okay? My last one sparked the same and it crapped out a few runs later. Don't know how to fix it.

The timing needs to be adjusted a smidge when there is sparking. Sparking leads to dead motors fast.

i've ran some hh7t pullers out crawling for about an hour un aware to break them in, should i still do the break in process now, or is it to late, also do the 7t pullers come correctly timed or do they need the small advancement (i'm afraid i'll screw up the motor the minute i untighten a screw

The pullers are timed neutrally when you get them, and are already broken in. Unless you see sparking in forward throttle, you are good.

Yep, just the one with sparks when you go forward. It wont need much adjustment.

wait what do you mean by sparks cause if i look underneath the brushes i see little blue sparks or if i give it full throttle it will shoot a few sparks then no more, also could the comms being a slightly grey mean it need to be , retimed and i'm sure its fine but its realy loud when going slow and when its fast is quieter (i thought it was supposed to be the other way around)

You really should see any sparks at all, but if the comm needs a cut then you would see a little bit of blue sparks from the brush jumping.

They are loud when slow because of the ESC.

Is it acceptable to use something like De-oxit D5 or Pro Gold? These cleaners/lubes work great on all of my other electronics. Will they also work on an electric motor?

Interesting about the Deoxit D5.

Other than a drop of lightweight oil for the bearings, there is no need for lubrication of anything else. Brushes have built in lubrication in the way of graphite, so no need there. The winding of the motor are covered in epoxy, so I doubt the Deoxit would help with the conductivity there. Might help in the brush hoods, but if they're clean, they should be good.

I don't know really, interesting stuff... never read anyone in the days of the brush motor popularity using it.

John, do you offer a comm cutting service? I want my 7T and 10T comms cut and buy new brushes. The puller arms are alittle too long for my comm cutter.
