Collector from Italy asked me to finish up an Italian molded mid 70's slot car chassis.
He provided the un-used chassis, a guide and John Havlicek built Mura "C" motor.

I provided pretty much the rest and it didn't take long... except for waiting on the mail and life getting in the way.
My opinion of these chassis is that they are beautifully molded and provide plenty of room for all the bits.  How they handle is a mystery since I don't have any swoopy tracks to test it on.  Only tuning can be addition of weight since there is no body movement at all with only an iso hinge in the middle which can be placed in one of four holes.

Okay, here is the basic chassis with the McLaren M20 body and interior as I check clearances.

 

And this is yesterday after body is painted and lettered.

 

Finished chassis, wired and ready for the track.

 

Requested were ball bearings at the rear axle so, I complied.  But it required a bit of filing to open up the holes about .020 more.  I suspect the standard running gear were probably metric.  Rear wheels are vintage Associated with re-purposed blue foam. 
I had intended to use these rear wheels for another build up, but the wheel diameter ended up too small for the project.  Perfect 7/8" for a Can-Am tho and painfully vintage for this buildup.

 

 

The gear is a FAA's with a ratio of 9/42 leaving a wonderfully smooth quiet mesh.  Nice car Riccardo, can I keep it? 

 

Stay tuned....

I wondered where that motor was headed, and now I can breathe a sigh of relief!    Beautiful work as always Jairus!

Final pics.

 

Wings are mid 1970's design, even if the paint is a bit more vintage than that.  But it's a Mclaren!  So the coloring is correct for the M20 even if I ran the fade from orange to a mixed McLaren color in the middle.  Artists license!
Body clips were bent out of .032 steel wire as I didn't want to sully the beautiful chassis with pin tubes.  (Can one solder to plastic?  I don't think so....)

 

 

 

 

 

Underneath it looks a bit like an old X-ray.  Weird....

 

Onward to the next project...

Very nice built, and a wonderful painted Mclaren, with the shadows at the rear wing, looks like  a real one.

 

Have a look, how we mounted the body: we glued some brass tube to the chassis and used the normal pins.

 

And: at that time we used 48pitch brass pinions. Gears came from Dynamic (aluminium) or Riggen (plastic).

 

Fantastic car!

  Can anyone give us a final weight for this type of build?  I'd also like to get my hands on one, definitely Thingie material!

[Mad Mark]

Really cool. I like how the orange body matches the chassis.

Here in the track !  ( Roncole Verdi , 12 october 2019 Meeting Thingies )

But Riccardo, how does it handle?  You have the best parts available there....

[Riccardo]

Tha competition did not include the partecipation of anglewinders. The car is very fast and well balanced , wheels needed runnin in but the lap time is in line with the anglewinders running last year. But...I use it with graet care .. it is too beautiful ( and fragile) !!!

[Jairus]

Keep some tire treatment on those blues.  They dry out.

Jairus, nice job. To improve the handling and avoid front-end lift, you could open the square vents on top of the front fenders. This body is one of my babies (made in collaboration with M.A.C.'s Lloyd Asbury in 1972...) and those vents were there to be functional. You can use a bit of brass wire mesh to make them looking cool.
