I guess I'm going to have to amend that page. I knew about using the resistor as long as the switch is off, but didn't say that on my page because I thought it was a "secret", and didn't want Patrick mad at me.
fastbaja5b: The 1717 is pretty low kv for 4s. To get any kind of speed, it has to be geared up, which does draw more current. So yeah, I would run 6s and gear more conservatively. And undergeared motor doesn't necessarily run hot - I find it's more about running the motor at WOT for extended time at any voltage. It just seems motors "like" more partial throttle running with limited top speed running. Probably something to do with how the PWM signal plays with the motor coils...
