I would like some opinions as to which older 16D motors had the most get up and go !
Sure, we have all come across motors that; for some odd reason or another; just flew
and were freaks. In the pics, I have shown some real fliers, and possibly the Chong is
unchallenged , but the Lenz and French are not too far behind, and the Dynamic Green Hornet
will keep up for a few laps, then slowly diminishes as it heats up. Any input, comments and
experience with these motors, and any other hot motor of the era, would be greatly appreciated!

Hi Zig,

Good to see you back on the board! Travels over for now?

It really depends on which model of each is involved, and from your photos it looks like the Chong is the only later model motor, with post protectors, magnet shim, etc. So it would normally be the fastest one of this bunch... Plus, I used a Chong on my first Thingie Proxie car and it won (even tho largely due to one of Gene's chassis...), so that's always a good recommendation. They seem to be very well built, very reliable motors.

I would think in pure RPM the Lenz or Dynamic might be the fastest, but that doesn't mean they're the fastest on the track - and any of these could blow up at a moment's notice! Model Car Science tested a few of the hotter motors in 1967-68 and published their results, that's about the only comparison tests I've seen from the time. Maybe this is your chance: get a standard Dynamic chassis, and try each one on a Blue King...

Good idea for a thread, hope you don't mind if I add a few when I get a chance!

A couple more hot or not so hot 16D size motors... starting with two hemi types, first one a Mura, second perhaps a Pactra but not sure if it's a real Pactra model or combined parts...

We Are the Champions!

Too hot for most of our vintage races!

QUOTE (howmet tx @ 7 Feb 2012, 21:14) <{POST_SNAPBACK}>Look, Don, seeing as it's got that messy thumbprint on it and is obviously not suitable for display, I'll take that right hand motor off you. Free up some space in your drawers, if you know what I mean.

Always anxious to help,


Gee that's awfully generous of you Mr. Howmet, and I'd really like to help, but some guy from the FBI just called and wants to check out the thumbprint. Says that neither me nor the motor should leave the country in the meantime, "if you know what's good for you".

Maybe in a couple years...

Zig, among other things it was one of the few of the later FT16D series with the metallic brush holders and endball drive, which was the preferred layout at the time by the pro guys and the rest of us! Easier to mount in brass chassis in any case...

Maybe Russkit also had some kind of distribution deal, because a lot of companies used their Russkit 22 and 33 in early RTR cars, and a lot of the rewind companies used the 23 as their building block...

K&B offered the Wildcat, which was also an endbell drive 16D, but with the floating rear bearing usually seen on the can drive models - don't think any companies rewound those.

A pair of Russkit 23s from an earlier thread...

I think the red-painted rewinds were by U-Go... assuming it's a factory rewind.

Zig, the Testor was definitely a production model, the Turbo MkIII or something like that, but with a regular coil spring and not the hairpin variety. They were statically balanced if I remember right, but not dynamically, and were only about $5, for roughly 26D type performance. Not much brakes, so maybe better on a longer track!

Hmm, with all these great motors, where do I start?

Mike, those are some fabulous examples, and rather rare! I've never seen a Mura Hitachi either and had no idea they had done one! Certus was another midwestern product, like Dyna-Rewind, and was becoming popular in the area about the time I stopped racing, in late 68. Still don't have one of those, but I would imagine their performance is similar to the Dyna-Champion class - have you run any of these? Plus, an Orange Picker in the box (only $10.95? that must have been after the price cut revolution, when racers rebelled against $25 motors... and the manufacturers got the message!). The 503 ain't easy to find either...

Zig, I've run a couple SS91s and they're very fast, still, with lots of torque - but no brakes! Have to gear them at least 5:1 to get any brakes at all. Not sure if this is normal, or because of 40 year old magnets... Seems there are still a lot around, so maybe adults were treating themselves to a 15 dollar motor at the time - I certainly couldn't on a 14 year old's budget!

As you figured, the red Strombecker Hemi is supposedly higher performance than the blue TC32, but the latter has pretty decent speed too, and that's the one they put in their competition kits. I think the set cars had a slightly milder version of the blue endbell motor. But the Hemi was also available in a couple versions: standard, adjustable timing and wind yourself kit. I have a standard one in my current proxy car...

Just as an anecdote, a couple of the pro racers in the early SoCal series used stock Hemi motors when their rewinds began popping circuit breakers on some of the tracks - so I guess at the time it was considered a decent motor.

Ray, not sure about putting a can arm in one of the open frame motors - it was usually the other way around, mainly with the DC65X (hi Rick) arm... or a Ram arm in the 36D. You could always try it, or just rewind the arm in the Scuttler (or use the 6V Avenger...).

All for now.

Can't swear to it Joel, but I think Mura also did regular pink-can motors, not under the Cukras signature. I have one of the flower-power motors, so will try to post a picture.

Love that smoky 16D with the skewed lams - shades of Lindsay! Too bad it doesn't work...


PS: Pink Playboy John? Sure your memory isn't playing tricks on you?
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.

The chassis that goes with that Cobra custom rewind, also a Cobra I believe...

First, Joel, those two arms look like Mura to me... I seem to remember the color combos, and Mura also did just about every combination of wire-wind, etc. ever invented!

The other arm I would say is a home-wind. I used a white epoxy at the time, Devcon, and I think a lot of other guys did too. The first Dyna motors had white epoxy, but much smoother, and they always used the cylindrical balancing holes.

That home rewind with the lams showing might be a dewind, radical style! And one of your motors also has those clips used to close it up once you had broken off the tabs, and were scared of drilling holes!

Thanks for the Hemi lesson Z - must admit I'd never noticed that STrombecker did both blue and red hemis, thought all the blueies were TC32s...

Not sure what the difference is between the two Pactra versions - and they also did a relatively rare 36D Hemi rewind, the Black Streak, with a black endbell...

Thanks John, always glad to see you posting!

Nice to see the Nordic motors, since I just picked up a couple well used versions. Were they just rewound, or did they have heavy-duty mags, etc.? I see the can clips made it over to your side of the pond too! How did they run compared to a Champion say? (speaking of which, nice Orange Picker - can I have it? )

You're right, the Black Widow probably runs better with only one motor, but it looks kind of naked like that... Is that your own rewind?

And yes, the Champion Ferrari really looks like an original! I think this was supposed to be about the fastest RTR car of the time, but it also cost something like $19.95, which was many weeks and months of pocket money for us kids... Still, compared to $15 for a Manta Ray, not that expensive...


PS: Z, just saw your post. Easy, if we all run Pittman DC706s that will eliminate the melting endbell problem!
Sorry, Nightrider, I may have erased your original dark & dingy comment when I deleted what I thought was a duplicate post...

Back to the motors, I may have been wrong about not having a rewind based on the K&B Wildcat (16D endbell drive with floating bearing, the only one of its kind...). Here's one from the Charlie Morito legacy that just turned up on ebay in the last few months, after disappearing for some years since his untimely demise... Not sure if CO was a brand, but it rings a vague bell, perhaps from Champagne, Illinois.. Looks like kind of an official label, but in a funny place for cooling...

A Mura rewind of Charlie's with home-made elephant ears/cooling-bussbars?

And a very interesting experiment, which we will never know if he finished: stuffing a Versitec/Globe 5-pole arm in a Russkit can, with ball bearing... Ladies and Gentlemen, introducing the Russitec!

To answer two earlier questions, first, a U-Go 26D with original label - the can shade looks about right:

And a tricolor 26D, perhaps a commercial rewind? can is orange painted blue or vice versa, and the back in Russkit gold! got me...

Beautiful chassis/motor combo, brings tears to my eyes...

I have a Flower Power motor Zig, but seem to have misplaced it for now...

But the Cukras motors were by Mura, it was just his "signature". And I also have a Cukras signed armature in one motor, not sure if that was Mura...
A couple more hot 36Ds:

The Green Hornet before (or after) it was Dynamic

The Dynamic version

Another French, and a Champion 707, still a beast, plus the earlier and rarer 705!

Another Lenz, or at least an ad for one...

And a Strombecker Hemi 400 AT (adjustable timing), stock, but theoretically higher performance...

Yep, possible* - if you want to try, I'll give you one!


* I think, actually haven't tried, but they seem to be adjustable separately if I remember right.

I think you could start a whole new thread on unusual motors, and I hope you do!

A few more hotties coming up as soon as I resize them and upload...

Here's a few more, starting with 36D and 26D. First, one of my Ram-Boochi motors, this one in a special lightened version and installed in an old GarVic frame, with dual friction drive! Actually runs very well, not disappointed at all...

A home-brewed version, sort of in the same vein, with Pittman style brushes, and a magnet shim. Looks like a regular 3-pole Mabuchi arm and can't tell about the magnets...

Cox's own attempt at a hotter motor, the Super Nascar, in 36D version...

And of course, the original hot can motor - the Globe Industries SS91 Screamer, released back in 1964 for rich slot racers - it was $15 at the time, but aerospace quality...

A strange in-between size, sourced from god knows where, especially known as the Mark 21, the only product of the Magnet Motor Corp, but also released by Classic, as the CM-550 I think - had never heard about this until I saw it on ebay and the forums. This would also make a good kickoff for our unusual motor thread...

26D land...

The Dynamic Green Hornet. I think Philippe has said this was actually a dewind, and subject to failure (at least the 16D version). But my 26D has already been very successful in several vintage races, after its initial career in England 40 odd years ago...

A French 26D in the ubiquitous Dynamic frame...

Home-brewed Champion style 26D, with Arco magnets and lots of cooling holes!

The model for the above, a Champion 607 (still based on the Mabuchi can, before Champion went to their own cans on the 517 and 617 series...

A Phaze III 26D, pretty much the same thing as the Cobra shown by Joel - either the same company, or they merged at some point.

See less See more
And back to 16D style motors of the chaud variety...

First a couple later generation Mabuchis, the orange one of course by Classic (another relatively uncommon model from this company, which seems to have provided an awful lot of 16Ds and especially 26Ds for home rewinding). The other seems to be a factory sample from Mabuchi, and I think that's what I bought it as...

I kind of missed the whole label on this one, but it's a Hem-Buchi, combining the stronger magnets and better can of the Hemi, with the easier to use Mabuchi brushes... not sure about the arm. It was "developed for Tradeship", perhaps by Mura...

The Dynamic Green Hornet, 16D style...

One of my later motors, a Champion I believe - maybe somebody recognizes the model?

A couple early Champion 507 style motors, still using the blue Hawk cans.... The one with the label was probably from a kit, altho not sure about that.

And here's a nice motor with the Cukras signed arm I mentioned earlier, perhaps a B can?

All for now...
