Still haven't found my Cukras flower power motor (stolen by a stoned hippie?), but here are a few more from the endless drawers...
First, in situ in a very funky chassis, a Chong from the Pacific Northwest (Bruce Chong, a racer in Portland, Oregon, who seems to have come out with his own line of motors). Got a series of four of these, and the motors, all different, are excellent. Some with silver wire and strong magnets, others seemingly almost stock - all very smooth!
Here's a Cobra "Custom Rewind", again based on the Russkit 23 like a lot of other motors in this thread. Silver wire of course... East Coast motors, and the company sponsored the "Gold Dust" twins, Howie Ursaner and Sandy Gross...
Here's a home-brewed version of the Russkit 23. Not sure what's up with the wire: either the color has changed, or the winder mixed in blue wire or thread with the regular red stuff... Pretty typical of what was going on at the time - before Arco magnets and US made cans.
One of the motors that started this thread, the Testor Turbo Mk?? (still haven't checked....).
And a couple Muras, Magnum 88 variety (that's the magnets, which also gave their name to the motor). The first one has "26" scratched on the can, and that looks to be the size of the wire.
And to finish up, a couple Champions. Actually, I'm not sure about the first, but it's in a Champion anglewinder chassis. Later model Mabuchi can, very professional arm with glassy type epoxy, post protectors... But it has regular drill hole balancing, maybe a bit early for a Champion.
Then a classic Champion 517, the first US made can I believe... 28 wire, and Champion's traditional slash balancing.
A home-brew Champion rewind, type 507. Probably a rewind kit, since it uses the blue can and has Champion factory balancing, with A, B, C on the poles and slash balancing.
