540 "Silvercan" Motor Variations 8 years 6 months ago #5092

I was reading this page on the 540 "Silvercan" & it struck me as not being very specific - I know there are two different manufacturers & that there are age-related endbell colour/material variations ... but I'm not sure that anyone has tried to document them. Looking at my cars that a) have silvercan motors in them, and b) provenance - i.e. a very good chane that the motor in there was the one it was original supplied with, I found up to 10 variants ...

Er, so what conclusion do we draw from this? I suspect Tamiya won't have stuck to using 1 specific motor type per kit type, & motor types are only loosely age-related. I would have thought a big company like Tamiya would have bought bulk batches of motors at the cheapest price they could at the time (Possibly 3 or more different batches /year?). Until noow, as far as I was aware, it was only ever Mardave that supplied the white endbell type, & back in the 80's, if I bought a replacement 540, that's what I'd be supplied with. My new '84 hopper had a 4-slot black motor, as did my new wild one & hotshot. My celica had a 2-slot black, my cheetah a 4-slot black & I think my quattro has a 2-slot in in, as have my hilux & rough rider.

I agree - but even loose "rules" throw up some car/motor combinations that are obviously wrong - my mk.2 Scorcher has a black metal endbell Johnson in it, for example ... if it didn't have a load of re-re parts on it already :whistle: I'd swap it for an "early" black endbell mabuchi :)

Oh yeah, I agree, use the bits that are likely to have been supplied with the original, but I don't think you can specify "An '84 'hopper should have a black 4-slot mabuchi" etc unless you know what day of what month the kit was packaged & have access to Tamiya's record of what was in their parts bins on that day... I still haven't got used to the Johnson metal end motors, they look chinese to me, & in my opinion, the later cars they were fitted to are dull toys rather than interesting collector's pieces, if you get me - I know I'm wrong, but I personally don't think hoppers, hotshots, monster beetles etc are old or interesting enough to be collectible, & still consider them "new"! (Showing my age...)

Louisbaby did some very interesting experiments with the silvercan.
It gave some extreme revs and torque but with quite the disastrous effect.
He sent me the coolest video of it a while back - I'll see if I can find it...

Here's a variation... :laugh:



That's what happens when you push it over 20.000 revs. :pinch:

That was quite funny at the time, But the poor motor is no more... We did get one of the motors to rev up to 19000 rpm consistently by shifting the magnets slightly forward in the casing. But my opinion is just to get a RS540SH or Johnson "4 hole" as I call it.
