A propeller test in a hex F550

Hi partners, as I promised some days ago I am going to post my propeller test in my F550.

I have a hex F550 and I am looking for the best efficiency in my setup. Now, my setup is:
Aux: 2080 gr
Motors: 2212 980kv SunnySky
Esc: 18A ztw
2.8 apm
Battery: 4S 5200 Graphene 15C

I have flown a battery time in each propeller. Each propeller has used about 88% of my 5200 4S battery and I have watched the time to notice which propeller has the best efficent.

If you write these characterics in eCalc you notice that the flight time is lower, so I can say taht I have a good efficent hex F550 ( my partner dkemxr). Moreover, eCalc says that my hex F550 flyes more time with 10" propellers than 9" ones. This is wrong.

The propellers that I have used are all made in plastic and they are: 3-blade 1050, 9060 APC, 1045 Gemfan and 9047 Gemfan.

The flight times were, and behaviour:
3-blade 1050..... 10:42 minutes. Stable in Stabilize but moves in PosHold and with windy weather.
9060 APC..... 10:52 minutes. Stable in Stabilize but moves in PosHold and with windy weather .
1045 Gemfan..... 12 minutes. Very stable in Stabilize but moves a bit in PosHold and with windy weather.
9047 Gemfan.... 12:30 minutes. Stable in Stabilize and does not move in PosHold and with windy weather .

So I can say that the best propeller is the 9047 Gemfan.

I have just bought the 9443 and 1038 propellers and I will watch these flight times to check if these new propellers are better that the 9047 Gemfan.

I hope you like this test because it took me a lot of time and money.

This is good data to look at . I like the fact that you recorded the weather / flight conditions as they can affect the overall performance by quite a bit .

This is great stuff. I have good luck with the 1038 props. I'm watching your tests to see how they come out for you. I'm betting (but not a big bet!) that they do even better, probably due to the lower pitch
