I raced RC cars for nearly 40 years going back to the late 70's (mainly 1/12th carpet but lots of offroad too), through the 27mhz to 40mhz to PCM to 2.4Ghz eras, through the NiCd to NiMh to LiPo eras and through the brushed to brushless eras but the single biggest huge jump was the introduction of brushless & LiPo together which was an instant game changer...there was no way back.  Long run times and zero motor maintenance meant more racing and less hassle.

For us RC guys the change itself wasn't so great as the cars already required an ESC and battery pack but the performance was a huge change.

There's nothing in our club rules stopping us using brushless setups but I don't see that same huge game changer happening for Slot cars, it's more of an alternative option but only for some classes of cars until there's much slower motors available along the lines of a 14k motor equivalent?

...as an aside, in those 8+ years of racing Slot cars I've probably had to replace a handful of motors.
