This is good stuff - thanks Dale. So, it sounds like the reason we have to limit discharge in RC applications is due to the very high amp draw from the batteries, and they can actually be discharged much lower at low discharge rates.

Your explanation for the using Whr is quite clear and I understand now. This is good news to me as I was thinking that the weight required to get a decent endurance for the paramotor would be excessive, but using your assumptions it looks much better.

The data I saw on the Joby motor site indicates that those motors are almost 95% efficient which should be considerably better than the Turnigy test data. I'm looking forward to seeing what you come up with in your testing.

Thanks for taking the time to explain.

Jeff
