... Some delta trikes only drive one wheel normally, so you might consider using only one motor. If using two BLDC motors you should use a separate ESC for...

Elden (& all): I don't see why this would be so. Let me put forth my understanding of DC electric motors and you all can tell me where my logic is off. A wire...

Hugh, Your description of how the motor works is very good, but omits the no-load performance. A motor with few turns has a high Io (no-load current) because...
