I recently picked up what for me for a long time in my youth was the motor of dreams , the Tamiya (Mahuchi) RS-540SD Black Motor Sprint

Every Tamiya build manual had them in as THE upgrade motor , long before I started buying Radio Race Car or Model Car Monthly the black motor was the motor of dreams for me and my friends to drool over , I never did get one , I did get a more mainstream dream motor the Le Mans 240s and it was a heap of fun but never really worked in my Hot shot as the run time was too short (I probably over geared it

) but it was not my dream motor or really my go to motor , not back then .
This leads me onto my go to motor , the one I kept buying and that was the Demon 27HT , a standard class motor that just really worked in my Hot Shot , the down side was the motor bushings , they just wore out really fast , one or two meetings ,maybe more if you were hot on the lube , I probably wasn't that good at maintenance back then

, I'd love to find a mint Demon 27HT but I just never see them up for sale and I guess they just got thrown out when used up .
So what were your dream motors and go to motors way back in them day ? , not what are they now but back then when it was real and new!
If a jobs not worth doing then its certainly not worth doing well.
A problem shared is a problem halved but an advantage shared is no advantage at all.
