This chassis was found on e-bay for 10 bucks.(just my bid) I felt like It had potential as a base for a Thingy.

It has a 4.5" w.b. and what really peaked my interest was the continuous pair of tubes that start at the front axle and go rearward, picks up the rear axle rods, then loops over the motor to finally bend out to act as  body mounts. Quite the roller coaster design. At some point I would like to try and bend up piano wire and use this chassis as inspiration.

The straight tube, front body mount, is 3'' wide.

I need help with ideas for the guide mount and what motor does this fit.  Bracket is 3/4" tall, screw holes 1/2'' apart. Bearing hole is 5/16'' ??

On further inspection the lower rails are bigger meaning the continuous rod that goes over the motor inserts into that lower straight tube and is soldered at the back of the motor mount.

Any input is welcome, I look forward to bringing this discarded work back to life.

Martin, I looked at that chassis a couple ties, but not too closely. From this perspective, the motor mounting plate looks like it fits a 26D .I recall Classic including 2 similar looking plates with each of their 3 26D motors. I thought that front plate was cut out to put a guide behind the front axle, but it would have to  be a small one, Didn't Monogram & others use small guides on their 1/32 slot cars?

Cool piece.

It might be for a Hemi.

Thanks Bill/Mike, the shape cut into the front axle plate had me stumped. I had not thought this could be for a guide. I was stuck on the Idea that it was for a drop arm.

So then if you are correct the guide would not turn. Is this a drag chassis?

I will look for a motor that fits.

Just ahead of the front body out tube there are two small drilled upright tabs.  Their position suggests that they are drop arm pivots

Also Alan, another set of pivots behind those that have been added. What could they have been used for?

This is why I reached out for your opinions. It never fails that I come away from these conversations with new direction.

Thanks to all.

It could CLEARLY have some weird made drop arm that would extend the guide shoe well past the front axle. (I can kind of picture in my head of what it would have to look like???? :mda: )

Just guessing the front brass section is some kind of modified drop arm.   I haven't looked, but could it be Monogram or Revell?   Obviously the guide part is gone.   Could a new drop arm have been fabricated to fit on top of the frame and anchored by the two upright tabs?

I thinks the soldered in axle support is from this monogram car as you say Matt.

I can make a drop arm that fits that key hole shape and extends forward past the axle as you imagine Mike.

Not sure why it is that shape or why there is another hinge behind the straight body mount tube?

This pic is from and ebay listing.    The top brass piece looks like the piece in your frame Martin.    I thought it was Revell, but I'm not sure.

That is correct, with a mating part on the right that would screw to the motors endbell.

 

I for one have never seen this chassis before.
