Thanks. It is totally OOB. I bought it from someone who has since passed on, who had assembled many of the sub-assemblies. I merely followed the instructions, checking what had been done and fixing what was needed.

As a matter of interest, did anyone ever build the motorised option, and did it work? I never built it but one of my father's colleagues did who gave it to me. it was a massive thing and even then I wondered how such a small electric motor - presumably the same one as powered the 1/24 aircraft propellers - could move such a huge and heavy car kit with all that friction etc.

 Looks like a crown wheel and a pinion - around 1:4 reduction, perhaps? Seems it would still be an awful strain on the motor unless you give the various bearings some light lubrication, maybe a touch of silicone furniture spray?

I would be terribly worried about letting it run, though - visions of it plunging off the dining room table or down the stairs!

OK, the motor might not be the same one as the one for 1/24 aircraft, but I still find it amazing that such a small motor (and power supply) could move that beast at all, especially with 70s technology. I really wouldn't have thought it had the power/torque to overcome all that resistance, especially as it was actually driving a shaft too as opposed to a pinion-to-pinion setup.

hey ratch

do you know where i can get some missing cogs as i am missing part 6n

regards

Oliver - a close-up of the missing part (in the instructions!) might be useful. I don't see it in the rear-axle area you've shown above.

Also, as Ratch says, try the Airfix spare parts service (click on the 'Contact us' link at the bottom of the page).

Failing that, there are suppliers on E-bay who specialise in parts for models and toys.

That's a lovely looking build too DaveCov. I'm not really a car modeller but I must admit I am tempted after having seen the images in here. However, I don't know my patience and/or skills are up to such a kit. Mind you, I wasn't wrong with the motor! Even if you had built it perfectly back then, I still would find it hard to imagine that such a beast could be powered by such a small and relatively week motor.

 I see what you mean about the big rectangular chunks on either side of the motor - probably big magnets to give more torque. There's quite a complex gearbox as well, more like a Meccano model than a styrene kit!

I've seen loose motor pinions for sale in hobby shops that cater to R/C and Tamiya-kit  type car racers - you may be able to pick up one that fits. You'll need to take plates 1G and 8G and the two gear wheels that fit in between them with you, as well as the motor, to make sure they all mesh properly.

Try Ebay as well, someone may have a broken model or loose bits they want to get rid of.

Best of luck and happy new year!

 

PS there's some scalextric motor pinions on Ebay that might fit.
