Cars of that period never used the end of the motor shaft fitting into a gear boss to locate the rear axle, we just put spacers between the wheels and the axle bearings. I had several cars with Dynamic chassis, they handled well.

You don't often see them on Maubuchi motors, but the ".22 shell casing" thing is probably the remnants of a commutator lubrication system.

There would have been a wick of some sort in the bottom of the casing that touched on the comm, and the rest of the casing serves as a reservoir for some sort of conductive lubricant.

This was common on the Pittmans and other "padlock" motors, especially for drag racing in the early 1960's.

Is that a K&B Bobcat?

It does look like a Bobcat. I had a bunch of those Dynamic pods. One I recall was a thingie I built with a Mura rewind, Dynamic brass tongue with a piano wire front axle, F-1 body, Monogram 1/32 front wheels with 1/16" adapters, and pair of Blue Magoo's in the rear that had been turned down to 3/4". It was fast and handled great. Closest thing to a scratchbuilt back in the day. :)

Oh the cars we've built - back in the day . . . . . almost sound like song lyrics!

To me the Dynamic chassis was just like todays HRS-2 chassis. It can be fitted under most 1:32 slot cars, handles well and is fast.

Interesting story to follow . . . . . I was racing up in Thomasville, Georgia at The Viper Pit. The owner of the raceway, Aaron Scott, also owns South Georgia Corvette. He also has a "Big Car Shop" on the premises where he makes lots and lots of horsepower in Corvettes and also Dodge Vipers. He has a Viper of his own that makes 1125 horsepower at the rear wheels. It's a very scary ride :angry-screaming: when you are the passenger! That's with no NOS! :auto-nx:

Aaron and I went out after the racing to have something to eat and we got to talking. He asked me where I raced when I was much younger and I answered, "Edison Raceways". I could see a bit of excitement on Aaron's face. He asked me about a person and the name was familiar. He worked at Edison Raceways and was now a customer of South Georgia Corvette. Well I got in contact with him and we met for a cup. John Becker was the person that mocked my Dynamic chassis car as "being 1/16 of an inch UNDER the track's surface!"

The car was an entry into an "Indy Car" race at Edison Raceways. I think it had a Honda body on it - yes I did see Gran Prix as was cheering for the Hondas. I will admit that I set out to make it as low and mean as I could. It had a rewound 16D motor in it and minimum clearance everywhere. I do believe the front wheels were the popular "pin wheels" from back then, you know the 1/16 inch axle type that were very, very small. Yes, it was fast and yes it did win that day. Like I say, the Dynamic chassis is like today's HRS-2 chassis.

We used those Dynamic chassis pods in everything, including the Grand National cars. I built one of those with a sidewinder pod, brass tongue, the Dynamic aluminum front axle piece with 1/8" axle same Monogram fronts, a pair of AJ's silicones, Champion 707 amp sucker motor. Every car on the track would slow down when I went full bore down the front chute. I got to run it 2 times and was told to change motors or not run in Grand National anymore. My pleading saying that we could run any big can motor fell on deaf ears. :lol:
