Turns and Winds again...

I can't stress this enough...

Most people look at a motor and only think about the "Turns", but that's only half of the options you have to play with. You can increase the "Winds" from a "Single" to a "Double" and you get:

1/4 the inductance
1/4 the resistance

...the effect is a cool running motor that spins well at low speed (assuming thin wire and many "Turns") and high efficiency and good top end power.

The RC people always seem smarter than the ebike crowd that always seem stuck on these darn hub motors. All I ask is for people to research "Winds" and then come back with an opinion. (I didn't understand it until just recently either)

Comparing your options:

"Single" - 40 "Turns", 1 "Wind" - 800 mOhms (example)

"Double" - 20 "Turns", 2 "Winds" - 200 mOhms

"Quad" - 10 "Turns", 4 "Winds" - 50 mOhms

...all will produce the same no load speed, but the "Single" will be strongest down low and the "Quad" will be strongest on top, the "Double" is roughly linear.
