Phantom 4 folding props

[Brojon]

Seems to me these folding props would be an iffy proposition given the pivots have to support the weight and thrust of the entire Phantom.

I would stick with OEM props, I have never seen any evidence that any third party prop has any advantage over dji props.

You're over-thinking this.

Using a 3lb Phantom (48oz) / 4 props / 2 pivots/ea = 6oz/pivot.

(Now maybe I have over-thought)

The bigger issue is flight performance for a system not tuned for them.

 

[Brojon]

You're forgetting thrust to actually move the drone: force = mass x acceleration (m/s)

2gs - 12oz/pivot.

I think it is strange any drone has folding blades since GPS or gyro birds' motors CONSTANTLY change speeds to maintain their position or stability. I would think that a floppy prop design wouldn't be the best for the instant acceleration and deceleration that these birds need for optimum performance.

If this is true, I'd get rigid props, if they are ever available, for my MP to get even better performance. If the centrifugal force causes the blades to perform just as good as rigid blades, I still don't think I'd get floppy blades for my P4...unless the provided at least a marginal benefit other than portability. However, this is all just thinking out loud.

Agreed*

I would be concerned with the difficulty of balancing these folding props. Being hinged the exact center would be hard to locate unless the Magic’s props have some sort of design built in that allows this. Does anyone know?

I think the effect of gravity was already applied in the 3lb static weight of the AC. You had it right the first time.

What is most relavent, as you pointed out, is if the aftermarket offering offers the same thrust and is engineered to perform reliably.

Don't see the point and the risk is high. The problem on the Phantom 4 is not the size of the props. The Phantom is larger as it is. I don't see props really being an issue. I simply remove mine and they are no longer any issue. Takes about 10 seconds.

One more item to fail with little if any benefit. The P4G is larger than the Mavic Pro and much larger when compared to the Mavic when it's folded up so any space savings with folding props are minimal.

The P4G is larger than the Mavic Pro

Is it a secret new model by DJI?

I changed my OEM props to those stronger (fibre......) screw on props and after flying 5 different times, one propeller flew off in flight and my Drone was in the drink. It’s in the box without a scratch, but it’s nothing more then a brick. Stick with OEM parts.

What about on our RC Helicopters. Have you seen the moves the pros can do? Even flying inverted?

 

[Matchlock]

Just curious. Since the Mavics' "propulsion system" is the motors, how are they "tuned" to use folding props?

FWIW the Mavic with it’s folding props is far more stable than the phantom 4 Pro.

Sample size: I’ve had three Mavic and 2 P4P, 110+hrs flight time across those birds, on p4p tried both one and 3rd party props, shot lots of panorama and HDR shooting where I’m super carefully watching the AC.

There’s also the ESCs and the aircraft’s firmware/software.

You can Google things like this to see DJI’s tuned propulsion systems.

 

[Matchlock]

Perhaps you can help me out here. Exactly what do I Google to find out about DJI’s tuned propulsion systems?

Thanks

The following link will take you to their OEM systems.

This same 'technical philosophy' is used in their RTF quads.

Thank you very much. That was interesting reading.
