Ive had the crazy thought of the 6 rotor go through my mind before.
But just now I had a great idea.
Ive heard somewhere a couple of times of making a car with two engines, like a front and rear configuration.
So the idea is get two 20b's, make a car with one 20b in the front an one in the back.
Then you can just call it a 6 rotor.
Or you can push the envelope with two 4 rotor engines, an call it an 8 rotor
How exactly you make a car with two engines, one powering the front an one powering the rear, is still a little bit of a mystery to me.
