Looks exactly like all the brushless motors in my RC aircraft. I've used brushless motors for almost 20-years now. If I want to go lightning fast in a slot car. I'll just buy a very small 35k high torque motor from Professor Motor for $12.95.
This silly little Porsche below spins/smokes the tires the full 19-foot straight at our club track. It's already stupid fast. It can't go faster.
The 2-key points about a brushless motor are the power to weight ratio, and efficiency. They are almost half the weight and about 30% more efficient. Perfect for RC aircraft.
To me, it's a waste of money for slot cars. To a person with an unlimited budget. It's another toy to play with.
I can already buy motors that are faster than I need to go to win a race. At a certain point a car can become absolutely no fun to drive. Take your finger off the trigger a nano second too slow, and you leave a Ferrari imprint in the drywall at the end of the straight. Plus, you break the car to bits.
I'm sure there are speed freaks celebrating the brushless phase. I'm happy that the slot car industry finally caught up to RC cars, trucks, and planes. The brushless motors for slot cars need to come down in price like they did for the other hobbies.
They also need to start making lower Kv rated motors for normal racers. Not everyone wants to drive a lightning rod.
Cheers,
