finished this up in recent weeks; had sat on my bench for almost a year as I figured it out. Based on the Aurora "Fiat Abarth" kit from the 1960's. Been on this kick of seeing how much I can squeeze into smaller cars: here I was able to include the kit's full interior as well as an Aurora driver figure, small as he is, at least he fits! Car is very "shallow", precluding just about every motor I could think of except for this tiny "cube" style mabuchi. Another challenge were the tiny wheels; some old MRRC press-fit units at the back drilled 2mm requiring me to use a current Carrera axle. Luckily from somewhere I found 2 tiny bearings, which were carefully epoxied into the kit's plastic pan to serve as a chassis. Breaking my "vintage only" rules had me dig out someone's 2mm beveled spur (Ninco??) to use in conjunction with their tiny pinion which was a near perfect press-fit onto the motor shaft. I had originally been thinking sidewinder with rear-mount motor, but the size of the wheels/spur precluded that as well, so you know where that led me: an anglewinder! Fiddled around forever getting the motor/gears in just the right arrangement, and finally secured the motor to the rear pan with both silicone adhesive (to minimize vibration) and resin epoxy. Teensy small gauge wire soldered to the motor snakes around the interior to the front where I decided to go with a pin guide with braid inserted/secured through the pan. Traditional flags were all too clunky, even the small ones. Front wheels are Campagnolo style plastic jobs, I think off an older Spanish slotcar, running on a 3/32 axle in the pan's molded in lugs for such. The other pair were ground down for inserts at the rear. A couple of computer board 4-40 "offsets" are used to secure the body to the pan.
The car goes well, but I am nervous with that tiny little motor on my 12v 4a setup, so I'm using my 60 ohm controller. Even then, I'm limiting my laps! Emboldened now, I have tackled my old Russkit Lotus 23 body which is even more shallow! In 1/32, this car is just miniscule!
