Oh well, I haven't realized that 19xx are inrunners! From the photo they stil look to me like outrunners. Definitively Neu motors are different from the rest because an inrunner 8 pole with such low kV I don't think exists elsewhere! Also in calc programs available on the net I can not find 1917 to be able to compare some numbers.</p>

In theory inrunners have less torque but can rev higher than outrunners, but this is just theory.</p>

I think that the only way to know exactly is to give Steve a call, or send him a pm, his nick is sneu.</p>

What I have previously written is absolutely applicable for all outrunners.</p>

I think I am going back to Scorpion, unless you make the experiment for all of us .</p>
