Eric and I both remember Champion muti-rod inline chassis for sale at Oakland Speedway back around 1966.  They were prominently located along the back wall near the cash register.  As Eric remembers, they were fairly expensive.  It was the coolest chassis we had ever seen.  Neither one of us could afford to buy one that day.  The inline Champion chassis were for sale at Oakland Speedway for a short period of time.  Racing sports cars were not really that popular at Oakland Speedway back then.  Everyone seemed to be running Formula/Indy cars or lightweight thingie cars.  Later on, Cox La Cucarachas seemed to take over.
 
I envisioned building a Lotus 40 sports car with a multi-rod Champion chassis one day.  Well, here is the car that represents what I had envisioned.  An old Champion chassis was cleaned up, and the center of a Russkit motor bracket was added.  The Champion bracket has a huge hole for a Champion ball bearing end bell.  The Russkit bracket piece fills the void, so a standard bearing endbell fits better.  Champion wheels and wheel inserts are used.  Rear tires are modern treated foam rubber.  The crown gear is a Weldun.  The guide is a shortened Cox.  The motor is a rare Chong 16D rewind.  I purchased a couple of these motors from a New York racer.  Both motors have a mild silver wire wind.  I reduced the motor spring tension a little.
 
The body is a Russkit, and the interior is Dynamic brand.  The body needed to be stretched to fit over the chassis.  The car has the look I wanted.  
It drives nicely and has neutral handling.  You can tell there is some mass with this car.  Most of the cars in this time period were lighter.  The motor supplies good power and brakes.  The motor runs cool.

Great looking build Rod! I think that brass rod chassis was made by AYK in Japan. The earlier version (same part #) had different body mounts & a brass rod drop arm. I never had either but often thought about building my own version. Those Lotus sports car bodies always ran much better as slot cars than the 1:1's did.

4.5 wheel base.I was missing the motor bracket and or the 2 I found neither has the champion script. Even the one still in the champion bag. Now if I only could find the side extensions I'd mount a 4.5" Champion Dodge Charger on it with a 26D!

Nice job and good project Rob. 

 

I don't remember being tempted by these, but I'm not sure they were sold at our local hobby shop either. Here's one I picked up on ebay about a dozen years ago, with a Champion 5001. I briefly tried it on the track, using urethane tires, but wasn't too impressed. Maybe it needs more power and/or sponge tires.

And here's this type of chassis along with the first Champion jaildoor. I didn't even remember these existed until I saw one for sale, claiming to be the first, and found it in the Champion catalog.

Don 

I noticed the jaildoors in your post aren't nickel plated like most Champion chassis.  Must be early versions?

I believe some of Champion's plating is silver & others had a yellow tint to it. Cadmium plating is yellow but I don't know if it was used. They also sold chassis kits for these rod chassis, but the photos don't look like raw brass to me.

Post #4 has photos of both styles of body mounts Champion used on these chassis. Neither one would be too difficult to scratchbuild. If you color them with a chrome pen, they'll look plated.

It's been awhile since I looked at these. No script because, there different?
They were dirt cheap so how could I say no?
