How to read the curves
With this curves it is easy to estimate the needed current and even estimate the flight-time.
- please note that the unit of the currents are in the most graohs in 10mA - that means: 100 is 1A and 1000 is 10A
If there are courves Thrust vs. Setpoint -> 2550 = 100% -> 1270 = 50%
You can get the needed current for each needed thrust
Example
The total weight of a MikroKopter (4 Rotors) is 1400g -> so each motor needs a thrust of 350g for hovering (1400g / 4 = 350g)
Current needed for 350g with the 13x6,5 APC - Propeller? -> 1,8A
Current needed for 350g with the 12x8 APC - Propeller? -> 2,4A
The total current for all four motors would be 7,2A (4 * 1,8A) or 9,6A (4 * 2,4A)
Flight time
You can estimate the flight time with this formular:
Time = 54 * Lipo / Current
(54 because we estimate 10% losses -> 60 * 0,9)
In case we would have a 3300 Lipo (3,3Ah), the Flight time for the 13x6,5 would be:
Time = 54 * 3,3 / 7,2 = 24,7 min
The same for the 12x8 Prop:
Time = 54 * 3,3 / 9,6 = 18,5 min
That is a different of 33% in flight time!
