Hi guys, it's me again :)
After braking one of my motors I decided to buy new ones but I don't know what motor to choose:
I've seen this one:
The problem is that on the ecalc it says that the hover is at about 67% of throttle.
I have a quadcopter with 3300mAh battery 40C 3s Lipo, 30A ESC with Simonk and a total weight (including the actual motors) of no more than 1,4 - 1,5 kilos and I was thinking to use 10" props.
Please I need help to choose a motor that allows me about 8- 10 minutes of a nice flight with a gopro (not more than 20$ per motor)!!
I would prefer longer time than aggressivity.
Any advice?
Cheers!

More important are the props you use on the setup to give it more efficiency. Main rules for efficiency in my opinion:
1 Use low KV motors for efficency setups
2 Motor manufacturers indication of prop size is usually rubish.. you have to test what makes sense and buy the props regarding to your tests. Best efficency I got with SF props compared to E types... as soon as you run your system a lot over 60-70%... the SF becomes far less efficient than the E type prop. As long as you stay around 50% throtle, the SF prop wins big time in trust/power consum.
3 If a motor is 3-4S... 4S is usually the better setup... so look for a motor that has 3S as max input.. remember that the engine batterie need to prop is oposit. If the manufacturer said: 3-4S Batteries and 9 - 10 inch props, you use the 10 inch on the 3S and the 9 Inch on the 4S version..
Hope that helped a bit
