IDK about that, I´ve been using them for almost a year now and they still perform very well. In fact they are very hard to break. Maybe UV rays can do some damage but I don´t really leave my copter under the sun.
They are for 5mm shafts, I really don´t know the DJI motor shaf dia. Making them 6mm is pretty easy. and they do come with washers for smaller shafts too.

You can find the three bladed props here (http://masterairscrew.com/).
I ordered the 11x7 and the 12x6 for my hex. Your prop size will vary according to craft weight, cell count, motor choice, etc......
Ohh thats sweet, keep us informed man!Originally Posted by BacklashRC
For reference, ill post some pictures of DJI motors with me measuring.
Keep in mind that the measure may not be 100% accurate, since i got a cheap measuring tool.
DJI motors have a hub with 2 measures, as you can see here.
The "large" size would be 8mm i guess:
The "small" size 7mm?
And with the DJI prop on it:
So i sent an email to Master Airscrew (http://masterairscrew.com/) regarding this stituation and asking wich props (3 blades) they would recomend for my config.
They asked me a few questions, i answered them, but they didnt answered me back.
I will keep you guys informed.
I recently switched to CF-filled Gemfans and I find they work very well on my 450 sized quad (HTFPV, w 1200Kv NTM motors, running 9x5 gemfans). A lot stiffer than the Chinese copies I got from HK. I had to drill them out to fit my shafts, but they come shipped with decent balancing from the factory also (unlike most Chinese props I've bought). They are slowfly design, so I guess not ideal for higher RPM, but I am OK with how they work.
A friend is a multicopter enthusiast and he tried Graupners and hated them - he went back to Gemfans. He offered them to me, but I am sticking with Gemfans also.
You say shark I say hey man Jaws was never my scene And I don't like Star Wars
might try those HK cheap props someday.
got to record an MK prop strike last weekend

I am a big fan of the gemfan 8x4.5 CARBON. They come relatively well balanced (minimal effort to balance them fully) and are pretty rugged - not to mention affordable! They definitely take small branches better than the non-carbon GF's, plus the non-carbon models are sometimes pretty unbalanced. I'm not certain if they come with the proper diameter converter for the DJI motors, but it's worth a look!
Graupner E-Props are my choice so far.
do not use the Stock props for very long...
Later,
Gundy
