Remember that comments are for helping to improve questions aqnd answers, not for extended discussions, and may disappear at any time, so important information should never be left in them. | |

| Jun 9, 2015 at 18:44 | comment | added | smeeb | Thanks @TobiasK - (+1 again and green check) - any chance you could send me a link to a 7000 Watt motor? I can't find them anywhere! Thanks again! | |
| Jun 9, 2015 at 18:42 | comment | added | TobiasK | First comment: (1) yes, (2) sure it depends. You need the right prop size. When you buy a motor you usually get spec sheet where you see the right prop size. (3) just ensure the motors do not interact each other. To the second comment : both the motor is pretty small and five kilos is a lot. I build a quadrocopter with 7000watt motor. This guy lift way more then five kilo. But ensure you are allowed to start quadrocopters this size. | |
| Jun 9, 2015 at 18:27 | comment | added | smeeb | Also, now that I'm actually doing the math on paper, are you absolutely sure you're equation is fairly accurate? This means that each rotor would have to supply roughly 1250 Watts of power. I Googled "RC helicopter motor" and randomly found this one whose max power output is only 114 Watts. Is this because a 5kg copter is ridiculously heavy, or have I done the math wrong somewhere? | |
| Jun 9, 2015 at 18:04 | comment | added | smeeb | Wow - thanks @TobiasK (+1)! A few followups for you if you don't mind: (1) Can I just confirm I understand you correctly? Say I want the "Hardcore 3D" flight capability, and let's say that my copter is 5kg. That would be 1000 W/kg * 5 kg = 5000 W, divided by 4 makes roughly 1250 Watts/rotor, correct? (2) Wouldn't propeller length also factor in here? And (3) Does the equation scale by number of rotors? In other words, if I had, say, 8 rotors would I just divide by 8? Thanks again! | |
