MMM availibility date dropped!

The main thing to look at is the efficiency "band" of a particular motor. I wouldn't dream of running Feigaos at anywhere near that speed, but a better quality motor surely can handle it fine and remain in its efficiency band. IIRC, the motor program Griffin posted a while back shows that the 15xx Neus are quite efficient at speeds upwards of 50k+. Granted, I am assuming that the CC Neu-based motors will have similar characteristics as a "real" Neu, but it should be somewhat close.

And don't forget that the total rpm will be affected by the current draw. Higher currents = lower real kv value.

And we can't just look at pure unloaded rpm efficiency. There is also load efficiency too. A motor running at it's sweet rpm, but loaded heavily by tall gearing may be just as inefficient as the same motor running slightly higher rpm but geared more ideally.

I guess we won't know exactly how these motors will perform until the system is released and someone can get some numbers posted, but I don't think it will be as bad as some think...
