I know I've seen similar chassis here before, but I recently was asked to build up a fairly "serious" motor for one of these.  Back at Roy Crawley's place, these were a thing for a little while, and they proved to be surprisingly durable and could be made to handle well with the right bodies:

The ones I remember were white, but it's possible there were other colors I had forgotten about...it WAS a long time ago after all.  Anyone else remember these things?

That is such a "KOOL" chassis John!

 

Would you know who the manufacturer of that chassis was please?

 

Thank you for sharing the picture.

Hi Ernie,

     I believe this one is European-made ("Monza" something or other...I think), and don't remember what brand the older ones were.  With 3D printing and scanning, I'm surprised someone hasn't copied them.  If the plastic the copies were made from was near as good as the old ones, they could do well for some kind of spec racing.

BINGO Mike!  I know it sounds "kray-zee", but I'm pretty sure we ran them with like G-20 type power, and probably some chassis tweaks allowed.

John I remember racing these too at Crawleys. Had to be mid '70's. Mine was white too. Don't remember what motors we ran and I have not seen mine around. I have most of the cars we ran there.

Hello John,

 

my little report on restoring such a car might help: http://www.jens-slot...1971/index.html

 

Popular bodies were: Ferrari 512 M Coupe or 612 Spider, made by M.A.C.

 

Looking forward seeing the finished car.

Hi Mike,

     Other than maybe adding some lead up front, do you remember doing anything to stiffen the motor mount?  It seems like it might be a good idea to somehow add a brace besides just screwing the motor to the bracket.  I built a 38/27 Mura for this project, and it seems like some added insurance might be a good idea.  :)

I agree John about somehow securing the motor better.  Maybe off of the rear axle. Pretty sure we added a rear axle tube and braced the motor off of it.

I was thinking along the same lines Mike.  Either bracing off an axle tube or even screwing some brass at the rear-end where there's a bunch of extra meat should work.  The chassis is pretty darned light, so any added mass, even minimal shouldn't hurt.  Some sort of a high down-force body (*as per above) and the thing should make for a pretty entertaining car.  :)
