I thought you used a watt meter to test and make sure the motor and ESC were staying within the range of the specs? That is a question but I was told the props in the range should be tested with the meter to make sure you weren't over or under on the watt draw? I'm up on my prop selection for glow and gas but I'm still trying to learn the electric operation.
I always use a Watt Meter on every electric powered plane I have. Even though the factory may list specs that worked for them, I'll still like to check and make sure what I'm using really falls within the specs of the motor and ESC, and they are functioning as they're supposed to. Last thing I care to have happen is the have ESC let out that magic smoke it runs on in the middle of a flight. I also like to try different props (brands and sizes) to see what performs best for my style of flying, not what worked best for a test pilot at a factory. Using a Watt Meter also lets you determine roughly how long your flight time will be so you can set a timer accordingly and have less of a chance to damaging a battery.
