16D motor for a Cox Chaparral 2E

I was an early teen at the hight of slot car hobby, there was several 1/24 scale tracks close by. We really got into it, built our own chassis out of brass tube and my 12 yr old brother would rewind armatures for more Rs so can't be hard to rewind a motor. We knew the shop owners so he would pull out a box of motors and power em up, you could tell the faster ones by sound and we got those.
Saturday night were races and we cleaned up consistently. I found a 1/24 track 100 miles away about 10 years ago and made the drive with my Son a lot, getting back into tuning and go fast again. They had wing body cars that were so fast you couldn't see em, some burned on track from over tuning.
I was having a blast until the track shut down, Bummer!! If I was rich I would build my own track. Great hobby, miss it!!


I found a vid of the wing cars, 2 second laps!!

I see several 16D motors on Ebay at the moment. I am not sure if they contain the special piece for the spoiler though.

Chapparel 2-E I assume is the only model that uses this motor?

Yes, I have researched D bay considerably, those motors, unfortunately do not have the large brass bushing that is needed for the wing attachment.

Could you not just  dissassemble the current motor and replace the armature and brushes with parts from another 16D?

Those can motors pop apart pretty easily. Plus you might just find it only needs a good cleaning and lube to reduce the friction on the armature that is causing the overheating. All it takes is a bit of hair or carpet fibers to bind an armature.

Wow is about all I can come up with.

Is this the model? I was a little surprised at the prices these fetch. Make a Strato Bug look cheap! In some of the photos you can see the cam that moves the wing.

WOW on the Speed and WOW on the Price !! They do fetch some big money ! Does the speed on the motor set the fin force ?

Roddie, thanks for the suggestion, I will be in touch with him

Cribbs, it doesn't quite work that way, I've tried that route and the armature is apparently different from most 16D in the length

Crnkbndr, yes, that's the one, although mine is the "cheap" version, that one probably has the magnesium chassis, mine has the stamped LaCucaracha style motor , similar to the one Roddie posted, it's basically the same chassis with an arm coming from it to activate the wing, it also "rocks" in the chassis so it can move the wing, hence all the issues trying to find the right pieces.
You've given me some ideas, so let me pursue those for now. I was out of town for a few days, so it took me awhile to respond, but thanks for the imput.

How this menagerie works, is thus.
The Cox 16D motor has a large endbell bushing, the plastic bellcrank fits on that bushing. (motor has no pinion for demo)



This goes into the chassis and the unobtainable wire link runs off the bell crank, the bellcrank indexes on a piece of plastic that is attached to the chassis to serve as up and down stops for the wing. (again, the motor is missing the pinion gear)



The unobtainable steel rod runs through the body and attaches to this small hole under the wing, when you gas it, the wing straightens out, when you le toff, the wing goes into an angle.

Pretty neat little setup, you would think it would work the exact opposite in that the wing would tilt down when throttle is applied to provide more downforce at speed.

That rod looks relatively easy to replicate. Not that you would ever need to, but it may help someone else down the line if you made a copy of it.

How is the search coming along?

Ron

I was thinking the same thing Ron , thats is pretty neat for a slot car to have that tecnologie. Thanks for the view and explanation of the wing to motor

WOT down straight a way no wing no drag....into the corner max wing down force
