Finished the second of two for Marty N. These were built, timed and wound to his specs, a #28 wind at somewhere between .3 and .4 ohm. The first was done as a Parma rewind with a Bugenis com. This one's got both the stack and com by Bugenis and is a very nice arm if I do say so myself

So hard a judge they hope never to meet as themselves.

It has a ton of brakes and torque! Just what I wanted
Well it's a big help that you specified the wind knowing what you were after. You also supplied excellent parts, and all that together makes for a good motor! I hope it works as well on the track, but I think it should. A wind like that in a solid motor like the Champ 26D is a pretty great combo.

John,
When you rewind a motor and put power to it to see/hear how the motor runs, is it run on power for just the moment or do you juice it for a certain length of time for break-in - so that each motor you rewind is already broken in and Ready-to-Run (RTR)??
Thank you John!

At most, I'll do two or three minutes on the power supply for a motor just to make sure everything's alright and get a feel for how it's working. So for people who want a full break-in, they gotta do it for themselves. A lot of the time, I'll also leave out easy stuff for people to do themselves as well like add shunts or maybe ball bearings. I just finished-off a batch of 8 motors headed for Germany (mostly old parts supplied by the owner) and if I were to break in every motor...I'd be there until tomorrow

That's exciting that you're performing motor work for people in other countries! I can understand why your work is sought after John!!!!! Terrific stuff you build!!
Thanks for your time.

Nice job Robert!! Is the arm on the lower right an RJR ?
Vic, if its not, it has an RJR comm.
Robert, what's the dia. of the 16D stack? Is it .560 or in the .513-.518 range?
I intend to live forever! So far, so good.

Hi Vic i am not 100% shore but i do believe the 16d is an RJR arm nice call on that one, wonder how these will work in my drag car i will find out should be interesting.
I think in the right set up with some nice stout magnets, you'll be very supprised !!

You may be correct about the magnets Vic at this point i don't think i will get much more out of a hotter wind with stock Parma magnets but when i go to the track i will have them zapped any way can't hurt.
Try a set of either Parma EPX magnets or Proslot FX. Give them a good zap and see how they do.
If you want to get real frisky you could try a set of Neos shimed up to around a 530 - 540 gap.

I think you'll find that the performance is going to be MUCH better than any speed FX motor! At least any stock ones lol.

First one seemed a little timid, but runs strong and pretty danged cool:
Second one seems about right as a balance between "heat" and longevity...more bettererestest:
Both were done on Tradeship (French) blanks with Mura coms reamed out and welded. Of course, they had to be installed in something to see how they run so a "Big Block" was in order. I guess in keeping with my "mixed nuts" series of motors, this one would be a Brazil Nut or maybe even a "Coconut"
As seems to be the custom, I fabricated a set of brush plates with leadwire tabs and installed some Parma hoods over those. I was going to make a set of "elephant ears" for extra cooling, but I don't think it needs them so I stuck a fork in it and called it "done". I might do another as a double wind, but I think a single is appropriate for these.
