"@R_Lefebvre: A) Did you happen to notice there is no "# of blades" variable in the induced power calculation? Also, don't forget the INVERSE relationship between Re and Cd at these scales. Slower is not necessarily better…"
"Brad, yes, that is symmetric blades, and he's also running a really high 3D-typical blade speed of... what did he say, 2100rpm? That could be dropped to almost 1200 with asymmetric blades. Well, maybe not with a 40lb load.
"@R_Lefebvre: Thank you. I have a new "day job" with a corporate software startup, hence my lack of participation lately. So, here's a run-through of the numbers on the stock TREX 700E example. Apologies for the…"

"Пожалуйста, поделитесь вашими настройками. Я предполагаю, что у вас есть ручной работы двигателей оптимизировать свои крутящего момента и мощности в соответствии с весом аккумулятора. С полки двигателей / батарей даст время полета 18/10 * 60 минут.…"
"Guys, this is really rather simple. You can do the math yourself, or if we can agree on some parameters, I'll do it for you. All you need are total weight, prop diameter, and battery capacity - with those figures alone you can…"
"Can you or someone else add the values on <eCalc> below, for a 114min flight or more? I did try to play with different values, but not able to get more that 50min.
Please post a capture screen attachment after that.

"I've been pondering on putting together a setup with ~400kv motors, multiple 6s1p low C packs and very large props... Should be able to get some decent hover times considering I can put it together with around 75% of weight being batteries."
"Аста, тут вот в чем дело. Когда предъявляют такой результат, с одной стороны это круто, бесспорно, а с другой стороны, это как отличник пришел, похвастался какой он крутой, и молчит, на вопросы не отвечает, ничем не поделится. Поэтому такое вот…"
