Bluefang,
I know you understand the benerfits of higher voltage. Hell you were the first to do it with our motors. Tell your brother I'll send him a nice present when he pulls it off.
UPDATE of MidMonsters specs:
It turns out the out of balance condition I still had what increasing no-load current by 10%. I balanced one today and the no-load current at about 1650rpm was only 1.8A .
FWIW, I chucked a HubMonster in the vise with no wheel and the Kv was slightly over 18rpm/v, and at 107.1V the no-load current at 1965rpm was 3.41A . We backed the throttle to 50%, and at 1000rpm the no-load current was 1.52A. It makes sense that HubMonster draws a bit more, since it has more steel and more torque for a given input than MidMonster.
Phase to phase resistance to come, which when combined with Kv and no-load amps can really tell you a tremendous amount about a motor. I'll get with some of the true experts and post a topic to explain in layman's terms the interactions, along with my ideas of how to look at simple motor specs (if we're lucky enough to get any at all), that give use a good way to compare motors and what to expect.
