@LitterBug - sorry to pick on you but your answer was the one I"m interested in (although the short answers are definitely valid). I'm not real proud of my electronics knowledge so I'm going to ask a few more questions. If you want to point me to something to read that's fine too. Hopefully this will help other folks.
E=IR
E=?, I=?, R=?Amps is what your motor draws depending on how much work its doing i.e. size of prop and you can measure it with a meter.
Watt rating - only the manufacturer knows that and sometimes they supply it.You said "The more volts you run, the less amps you need to reach the same watts (got it). If you limit max throttle below the smoke point, you will be fine."
So in the real world do you limit throttle or prop size or both?
I guess the simplest answer it to buy a motor rated for 4s or just go to a more powerful, heavier motor.
Safest way is to limit the prop. Bench test with a watt meter attached , also good to have a heat gun to watch the motor temp and start with a very small prop and slowly work your way up.
