I was looking around and came across a three blade carbon fiber prop. Has anyone used these on a mavic 2 pro zoom and had any luck flying with them ?
Thanks
Thanks
Besides M-helps reply, a recent discussion also suggested that carbon fiber might not be best if the drone were to strike something, even a tree branch. The strong carbon fiber might resist easy breaking and transfer the force to the engines or arms/legs whereas the DJI props might yield/break and not transfer the force.I was looking around and came across a three blade carbon fiber prop.

If they really were an improvement, we'd all be flying them and DJI would have put them on as standard equipment.

In addition, as I wrote in one of those threads, DJI has magically created a four pound weight that can fly and fold up nicely. I guess I trust them to design appropriate props for this miracle device.
I stand (on the scale) corrected - 2 pounds. I still consider that it flies magical.What weighs 4lbs
There is no free lunch. Lower RPM for the same thrust requires more current which equates to more heat and increased IR losses (lower efficiency).That's true.
They could run smaller dia blades, and / or marginally less pitch.
I suppose though the main benefit with the concept is they could give longer flight time, lower motor revs for lift, but then that may long term reduce motor life with extra torque needed ?
The other thing is with folding tri blades there is another point of failure with another blade attachment point.
All FPV racing type drones seem to run tri blades, but they all seem fixed.
Not always the case - I run Master Airscrew prop's on my Mav Pro Platinum, and they spin at lower rpm, but give me about 2 minutes extra on the battery - so that's telling me that the prop's are more 'efficient' than stock DJI (& Carbon Fibre).There is no free lunch.

And you don’t think if there was an easy 2mins to be found DJI wouldn’t have done it? The most likely explanations would be cost but there are others obviously.Not always the case - I run Master Airscrew prop's on my Mav Pro Platinum, and they spin at lower rpm, but give me about 2 minutes extra on the battery - so that's telling me that the prop's are more 'efficient' than stock DJI (& Carbon Fibre).
Another thing to consider with carbon is that it could make a shield over the AC and give problems with the gps receiving.
Well DJI obviously haven't done it - as the cost of the MA prop's are pretty much the same as DJI 8331 prop's ... Master Airscrew has been designing propellors since 1976. DJI has been designing Drones since 2006. There is a difference in focus as well as experience, and in my opinion, MAS make the best prop's, and DJI make the best Drones - but the combination of the two takes it to another level!And you don’t think if there was an easy 2mins to be found DJI wouldn’t have done it?

So cost might prove not to be the explanation. There will be a reason. DJI are in a position where they can buy the best external expertise and have the numbers where tooling for even the most exotic of mould shape for production wouldn't be a problem. Do you know how much closer to the design limits the power mosfets in the motor drive inverters are running? Are the props accelerating (RPM. change) within the design target when increased thrust is commanded by the flight controller? You can easily make a long list.
