I think motors are at least as essential, if not even more, in 43rd scale than chassis because motors determine the possible minimum dimensions of 43rd scale slotcars and the drive principle - inline / anglewinder / sidewinder .

Until now one primarily sees closed cars - from saloons to Group C or GTP or whatsoever.

But there are lots of beautiful open cars - from Vintage via CanAm up to modern LMP´s. Their general drawback is the height. They all are rather low, especially the modern ones.
The actual popular motor sizes are either something like the GO! dimensions or the Mabuchi SH-030SA.
The GO! - size enables anglewinders and with a bit of tweaking even sidewinders - always assuming SCALE wheel diameters. But it is too high for real scale open cars.
The Mabuchi is low enough for such cars but too wide. It can only be used inline and at a rather big angle as anglewinder. But especially the moderrn spyders are quite low between the wheels. Well, a little compromise in this area of the body wouldn´t affect the overall appearance anywhere near the too big wheels on the LMP´s of a famous German Producer.

So wouldn´t it be a useful research action to find out ( or even to show ) what is available AND being used ?

My first attempt was the motor shown here on the right. Much smaller thatn the GO! on the left. Neos. Arm shaft 1 mm.
But : Its voltage range is between 5 volts and 12 volts on the data sheet, and in reality the motor starts running at 7 volts. The power is too low.
In my opinion it should be possible to get a usable motor from this basis. Probably a matter of winds / wire dia.
But how to find out ? Pre - finance some experimental changes with the producer ? They even wanted 40$ for the five samples...

Well, come on, what "tiny" motors do you have ?

Hi Roland, I have several small motors in my box that I have yet to try. Although I also do proxy races, my main building is for 1962 to 1972 rally cars, so out and out speed is not always what I need.

The smallest are the phone type motors, which I will be trying, using belt drive, in my small engine class cars, original FIAT 500 etc.

I also have a small can motor that fits somewhere between the phone motor and the open Mabuchi motor as useh in HO cars. I have not tried this small can yet, but hope to soon.

Most of my cars will use the HO type Mabuchi as it has plenty of performance but is low enough to allow reasonable interior detail.

The Radioshack/Carrera Go/ SCX Compact type cans have plenty of grunt for my fastest rally cars on my routed wood rally track and, with the right gearing and tyre choice can be very quick on my Carrera Go plastic track as well.

I do not use the big motors as found in Artin and similar as it does not allow for interior detail.

That's my list at the moment, but if any new motors that fit the bill come along I will , of course, try them out.

Regards, Lloyd.

Although I have little knowledge of HO racing, I understand that there are some very hot open frame motors used for serious racing in that scale. Does anyone know more about them?

Regards, Lloyd
