Its not unlikely that there has been motors surviving far longer.
There is no Professional electric 1/8 scale onroad racing. But thats where i think the threshold is just about. If there was a 1/8 scale electric Pro scene with cars and electric systems designed spesifically for that they would be easily faster over a 10-15min race.
the norm is usually a converted nitro car.
Its only the smaller and older Brushless motors that goes very high on revs.
Once the size goes up the rpms goes quickly down. just like in real life getting enough power is usually not the problem. Battery weight and runtime is.
that said. without the motor size rules and so on they would have quickly made the motors smaller. as they are quite large on a 1/10 scale rc car.
go do brushless motors and red series sensored their 3.5T is rated for 1800Watts burst.
a pro driver uses motors rated probably around 500-800Watts 90% of the time.
