I've noticed that many of the different motors (Axi, Hacker...) have the same wotor w/ different amount of windings(SP). What is the reason for this and what would be the application differences? I'm mostly learning 3d while my family is on trainers. I would like a motor that can be used for all apllications with lipos.

Thanks,

Rob

You will have to be a lot more specific than that. Without knowing the plane you want to fly, no one can suggest a motor.
