Hoi Nick, veel plezier hier!!

The props do contribute to both the MP ánd the MPP's noise generation but it's the motordrivers that make the difference.. The MP with the low noise props is still much louder and annoying than the MPP with low-noise props!

The motor drivers in the MPP send sinuswaves out to the motors, the MP drivers send out block-shaped ( steep rising and falling ) signals which cause any coil to generate steep contra-currents as coils don't like to change their magnetic status, hence they "scream" more than the smooth driven...

Nope, slower RPM with same lift-forces cause higher currents in motors hence less flight time ( in hover/static location ) . Did not perform in-flight comparison so cant tell dynamic behaviour.

Basicly yes, i just mounted a lightweight box on top of the mavic to stay close to it's original COG, and put in sets of 4 grams of wheights in order to gradually increase load as you can see in the Exel sheet. All the other initial base/dat is just combinations of Tares from MPP, the basket...

@FoxhallGH Were you able to read the post? Just checking!

@surfbird: Thank you Surfbird for your great feedback! Your work confirms my suspicion that the lower RPM are linked to higher torque hence higher currents and impulse resistance of the coils...hence higher losses at the end... Interesting data!! All of you Hovering work is not a mistake and...

No, not, where did you find those?

@TexasFlytography : Thanks! Your question: That would vary per application: a distinct difference between the 8331 and the MAS Stealth can be found in the delta in rpm and the more"flat" graph the MAS shows while processing heavier load. To my opinion this is due to the material and the...

As promised quite a while ago. (assuming all datapoints are correct ) When taken a close look at the differences it clearly shows where the props would find their applications. The 3blade Carbon props give high-wind alarms for a reason: RPM's are low from front to back of their...

Actually i provided hard data that supports the MAS claims, see my thread on testing props.

For some enhanced insight in how various props perform just have a look at the tests i performed in order to characterize/fingerprint a small group of various props: it also includes testing a cheap china counterfit that clearly underperforms at a given point..

@sar104 : I deliberately decoupled any basic units like Current and Voltages from the equation to keep things more general: some tend to tune or tweak the driver responses like min/max currents or the PID response of their bird's motor drivers hence making this fit for general interpretation...

An interesting find is that the spread between Front motor RPM ( RPM_F ) and rear motor RPM ( RPM_B ) vary per propeller type and never show overlap. the most significant delta between Front and Back RPM is found on the cheap flexible chinese copy props, increasing almost exponentially at...
