DJI 9450 Self-tightening props (pics)


The 9450s have arrived! Big thanks out to Dr. Turbo for the opportunity to test these out! My favorite part? They're called the "Thrust Boosted Version"

A few comparison pics and measurements against a standard retail set of E300 9443 whites (I still can't believe how many of these I have, and whether I'll be pushed to replace the whole lot):

Packaging


Close-up of label:


Unwrapped (the 9450s are a tad yellower, probably due to plastic batches rather than intentional dying:


View of the profile - I may be holding them a bit askew, but the 9450s definitely have a bit more bite to the trailing edge:


Closeup to show the 9450s seem a bit thinner and more aggressively angled at the root:


Measurement at the root (note this isn't the actual width of the blade since the face is angled, it merely illustrates the difference in profile:


Measurement at the widest part of the plate (again, not the actual width since the 9450s are angled more steeply):


I haven't had a chance to fly them yet, but I'll try a test flight today, and hopefully try to get a back to back fast-descent test (manual mode descent?), and hover-time test before the weekend is through.

Quick test flight: 9443s take roughly 20% over center to hover in manual, 9450s take about 10-15%. Noticeable difference. I'll try hover duration next.

Great idea with the caliper,ElGuano, its so hard to notice from the distance,



that I destroyed one of my grey ones to notice the difference



I like, that the 9450 are coming significantly stiffer (Is this the right word?)

Haha nicely done. I should have taken precise pictures and superimposed them like you did.

Yes, the 9450s are a LOT stiffer. I actually really like the super thin grays, but realize that there aren't a lot of other props like that out there. The 1038s are stiffer, and thr e600 props are also very stiff.

Not sure, I think they should be released very soon, assuming they're not already out. I would call and ask your shop if they plan to stock any.

Dr. Turbo says there are thousands of pairs being sent out now, so it should be imminent! Also, that DJI would well them direct from their website soon...

ElGuano, in another thread where I was asking if I want to upgrade my P1.1.1 props, you suggested to wait for these. This was before you did testing on them. Do you still feel they are good upgrades to move to?

Thanks!

Thanks!

Hi Ben,

Here's where I landed on the 9450s:

I fly near sea level; and I've never had a p1 or p2 with 9443s go into to VRS or uncontrolled descent. I'm also more careful than the average phantom pilot wrt the payload of my quad. In cases like this, the 9443s are just about perfect, they have no downsides other than not being great for sportier flying.

When I travel to altitude (5000+ft) the dynamics of the 9443s change dramatically, and I've also talked to testers who claimed the extra thrust from the 9450s provided better lift in thinner air. My sea-level testing in manual supports that but I haven't gone to mountains with them yet.

So at home, I leave on the 9443s. If I travel to altitude, I'll pack the 9450s instead. For flyers who are dealing with hover/lift problems or VRS on descent, I would definitely recommend trying the 9450s, they make quite for a difference in the air.
