Cox / Thimble Drome Corvette

Just seeing the photos gave me chills.
Shrine worthy for sure. Thanks for sharing.
Any ideas of a production date? Maybe '65?
Bob

Thanks for the kind words. :)It really is a neat car. When I look at it, It reminds of being a kid back in the 70's and going to Western Auto or Ben Franklin 5 and dime and seeing all the Cox cars and planes on the shelf and begging my mom for one.
As for the production date, I would say around '65-'66. Unfortunately, Cox didn't print any dates on the box or paperwork.
Maybe someone here could chime in on that.

28,000 RPM from a Babe Bee!!!!!! Does the engine spin up faster on the ground than the air?

A little off-topic, but in the eighth picture with the catalog: What is the handle with the push button on top and electric leads coming out of the bottom?

The Mystified Mark

I'm guessing that's a slot-car controller Mark.

That's exactly what that is.........I had one once.

One thing I found interesting about this model is the cylinder was shimmed out with a riser to lower performance for circle running.
For straight line running, shorter runs and less overheating, they said to remove the riser for better performance.

That's one I didn't about know Doug. Thanks.
While we're at it, does that engine
pre-date the hd case and crank set-up?
I have a hd case/crank with the splined nose on the crank,
and was wondering where it might have come from.
The splined part of the crank is bigger (od) then the
stock Bee one. Still looking for a prop driveplate that'll fit it.

Bob I never broke one down that far, but I think thats an HD case, large journal crank splined on to the flywheel.
Maybe someone that took on apart knows for sure.

Hi Bob,
Yes these engines have the Heavy Duty case and splined crank with (IIRC) the large splines and you'll have to find a flywheel specifically for the cars. However, the funny cars and all worm geared cars were the exception as they used the bevel style crank as pictured below.

I'm not sure what the true RPM's are, but they spin up way faster as there not is as much load as there would be with a prop which "over spin" is one of the reasons why Cox used the cylinder shim when running on a circle track. It would be interesting to try and figure out a way to tach one.
