How do the Velocity inrunners compare? I wish to find the best motor, for 1400 watts on 70mm 10 blade fan, like the Cool42, but I'm inquiring about how the electrical efficiencies are. Do the inrunners compare to outrunners for 85% or better watt in watt out?
If someone could clarify...the Cool42 is a hot motor, for 90 bucks....as are the neu and arc motors...but which uses juice more effectively?

I'm aiming for fast and long run time...
