Interesting Motor

That looks like a little less the 23 turns to me, maybe a 15 single or something along those lines judging by the thickness of the windings. Super cool piece of RC history

That's a real early check point motor that uses slot car brushes . His background was slot car motors before moving into r/c motors. He used those brushes on his Platinum motors too.

Never seen a modded stock motor like that. That is a serious piece of history. Big Jim's motor black book is worth some serious coin now since he passed away so hang onto that baby.

camlchris and Mad Racer: Thanks for the additional info! I'm definitely going to restore this now. The brush work inside the endbell is really very nicely done.

adam lancia: I'll try to count/calculate the windings: 23 does seem high.

Regards,

Robert

Wow, pretty complex compared to most closed endbells! Looks like the nailpolish isn't original, maybe it kept the can in good shape!

This is my Checkpoint, but without any label. it is single wire.

Nice! It looks very similar. I wonder if the can on mine is supposed to be unpainted as well.

WOW - I remember seeing one of these when I was a kid at the race track - must have been very late 70's or early 80's?

Damn - thats a rare bird surely??

It may have started life as this before being re-tuned by Big Jim. I imagine the endbell / can were also taped so you never saw the poor paint work underneath?

How did this Parma Ferrari performed??

A link to Igarashi motor page http://www.rc-car-museum.de/Die_Entwicklung_der_Motoren/Igarashi/igarashi.html. Through Google translator others than German speaking can also get something out of that.

Hint: There are lot of good stuff in that page!

I'm pretty sure that's the way the motor came when new. Big Jim was the first that I know of to use the sliding brushes. I seem to remember they were very expensive at that time, maybe even pushing the ROAR price limit for modified motors. Performance was good, but Jim always liked a lot of horespower so it made it tough to run 8 minutes with 1200mAh cells.

The cans were painted red and had a label applied. I think the labels were a little too thick and some of the guys would remove them to get more suspension clearance when using RC12i cars.

I also think Big Jim was the first to use silicone wires in a production modified motor.

Great find!

Thanks for the additional info, Kent! The label is quite thick; it's actually two layers, the top being a clear mylar-type material.

RC10Resto/Jirka: this motor certainly looks similar to the Parma Ferrari, the endbell appears to be the same, but the can is different.

that endbell is awesome.
