Smart thinking Nico.

Figuring out the gearing should be a fun experiment.

Please post a brief report in writing so some of us need not sit through a Youtube video being called "boys and girls". Some of us "boys and girls" are a bit older than you. You might even call us old farts. You'll need to watch the movie "Grumpy Old Men".

Your new address to the people could be "Boy, girls, and not excluding grumpy old men". Just kidding. That'll never fly either.

I hope you have fun with your new lightning motor!

Cheers,
Ken

Because it's not controlling the power to the motor, your hand controller does that.  In an RC car/plane/boat/heli the ESC controls the power to the motor, your hand controller tells it by how much.

The Ecomm is just a single phase to 3 phase converter.

Your hand controller is not much different from the throttle stick on a transmitter. The only difference I can see is one is direct, and the other is through a radio.

OK, let's go back before Esc's were invented, I raced rc cars in that era too. 
Cars had a wiper resistor operate by a servo, the exact same wiper resistor seen in parma controllers. This was the speed control and could be operated by hand with the transmitter off if required.
In a slot car setup that resistor is in your hand control not in the car, the car is connected in series via the track. 
When Esc's started coming out in the 80s, my first was a Demon I think and that was electronic rather than resistor, later becoming mosfet and mosfet 2.
So it's not the same thing at all, the variable resistor is still in your hand controller whether it's a brushed or brushless setup.
