I was thinking of listing some harder to find Dynamic stuff. I would not call any Dynamic stuff "rare" in the true sense of the word as so much was produced. However, after 40+ years some of it is very hard to find.

These are chassis for the Dynamic GE Silver Hornet motors. They are both Dynaflex type.

First you have the sidewinder version. A little tip, if you do find one of these make sure you have the motor spacers I have shown with it. The used one has Champion silicones on it.

Next is the inline. Two defining features are the pronounced step up at the rear axle stands and the slot at the top of the motor ring.

Lastly is a shot for ID purposes.

What's the most fascinating about Dynamic is the multitude, not to say plethora, of parts and adaptions for different kinds of motors that this company kept pumping out in the relatively few years it was active in the market. Especially remarkable is the one-off motor pods for the odd single motor, like the Russkit 36 size end bell drive motor inline pod for the Swinger/Hussein. I didn't think the process of casting aluminum was, and still isn't, such an easy feat to accomplish. How did they do it in this relatively small scale business?

I really hope PdL has got the Dynamic story well sorted in his upcoming book.

Moving this one up to the top one more time since it didn't get many comments.

Good idea Joe - in fact, I missed this the first time around! Probably drinking wine and eating foie gras as usual...

Responding to Bertil, in fact Dynamic was around a fair amount of time, compared to a lot of the other slot car companies, and they were there from the relatively early days (63 I think - maybe I should go look at PdL's book!), until well into the anglewinder era. A lot of others lasted no more than 5 years, even less.

I had always sort of looked down on these, since they weren't brass, but in fact having seen a lot of them on the track in vintage events, I've come to greatly appreciate the Dynamic chassis and their whole system. Given all that's still around, they must have sold a million parts, everything included...

Joe, on that sidewinder chassis, any hints on the idler gear? It was a long time ago, but the first one I assembled, I put on the track and the whole middle assembly fell apart within a half lap... Don't remember what I did or didn't too, but I obviously didn't do something right!

These days they wouldn't even need an idler gear, since I think that was only done to use the small tires popular at the time. With more or less scale tires, a regular sidewinder works fine!

DON ,
You obviously don't think like my younger brother . Back in the
day , ( Think circa early 1968 ) , he hand built an aluminium sidewinder with
an idler gear , which moved the motor forward enough so that he could
install a third orange sponge tyre on the axle between the chassis up-
rights which held the axle bearings and directly behind the motor that tyre
sat . Takes it too the track and he found grip where others didn't . A great
leap forward in slotcar technology . He was king for a day . The car was
of course deemed to be illegal . You've come up with your share of unusual
or innovative slotcar miracle finds . Tell us about some glorious dead ends.

BRUCE NEASMITH.

I do but the detail of all what was made would be intensely boring, so I limited the story to the major products (mostly cars and motors) and will leave the detail of bits to the Internet interactive site that the book buyers will gain access to. :)

Joe, please tell us about the brass pan on the SW.

Bob, not much to say on that pan. That is just how I received it in a lot purchase. It is home made but nicely done. When I got it it had no body and no evidence of mounts so I don't know if it ever actually made it around a track. The whole thing is very heavy and I doubt it was a world changer.

Don, that idler gear setup is poorly designed. The chassis with the motor has a piece of tape trying to hold the nut that the owner used as a fix that didn't work. The whole thing kind of flops around and if you tighten it it locks up. I am sure that's why yours fell off. They should have used a nylon lock nut or something else to keep the adjustment.

Joe, the pan looks to cancel out the effect of the drop hinge.

Mike Z got an idler set-up to work and last the Dynamic Proxy.

IIRC, I believe there was a second reason for the idler gear; to move the weight of the motor forward for better F/R balance.

Here it is... found this in the Auto World catalog section on Rick Thigpen's website... there in the lower right corner... "Idler gear concept moves the sidewinder motor further forward on the chassis for improved center of gravity."
