Zeile 13: Zeile 17:
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)

[[http://gallery.mikrokopter.de/main.php/v/tech/MK3538_characteristic_curve_0-8A_howto.GIF.html|{{http://gallery.mikrokopter.de/main.php?g2_view=core.DownloadItem&g2_itemId=67421}}]]

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!

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)

http://gallery.mikrokopter.de/main.php/v/tech/MK3538_characteristic_curve_0-8A_howto.GIF.html

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!
