ORIGINAL: rosnik Thank you for info about SK3 5055-430Kv, DrMotor!
It was a pleasure, rosnik. Thank you very much, for continuing to contribute to the thread.</p>
Can you please get measure with APC 17X8 with 5S too?
Here are DriveCalc results for 5S LiPo, on the Turnigy SK3 5055-430Kv motor, using different props: I have included the results for 16x8 to give a comparison with the other two:</p>
prop Current (A) RPM Thrust (Kg) g/W
16x8 46.2 6606 4.57 5.3
17x8 50.1 6486 4.53 4.9
18x6 50.1 6484 4.82 5.2</p>
There is no 17x6 prop on the database that I can test.
As you can see, a 17x8 prop draws more current than 16x8, and actually gives slightly less thrust.
The 18x6 prop draws exactly the same current as 17x8, and gives more thrust than the 2 other props. Its g/W value is good, at 5.2.</p>
Seems to me, that props to definitely try on the REAL motor, would be 16x8 and 18x6 ...</p>
Pic attached, shows the simulation for the 18x6 prop, with 5S LiPo (18.5V).</p>
