thought I would post this here as well. i was really interested in seeing how the X Star would perform with a really good set of props. So, for 40.00 I ordered the Aeronaut CamCarbon 9.5" props from CarolinaDronz. I have only flown several minutes with them on.... 1st impression...WOW, I MEAN WOW!!!!!!! This is a different bird, no doubt! #1. Noise. It is SO much quieter. More than 10db quieter (I used a db meter) #2. Hover. MUCH more stable and doesn't move barely at all where the XTR blades let it kind of creep around a little. You might say that yours doesn't move much at all until you see it with these on. ROCK solid. #3. It seems to scoot a little faster, but not jerky, a smoother transition when you move the sticks. Just better handling. #4. Descent, you get barely ANY prop wash at full speed descent. Much smoother coming down. #5. Ascent, again, seems to be faster and smoother #6. Yaw. Definitely smoother and not as jerky...still needs the update to correct this. So far I am totally impressed by these blades. I will do a real life battery test to see if there is any benefit. Will also check motor temps as well. I might be able to get to it this weekend. Weather looks to be good. CAUTION: These blades are stiff and sharp! I can assure you I will NOT be flying with these props around people at all! my uses because of the amazing stability they have... Time lapse sunsets/sunrise Tooling around mountains, nature and far from people. Flying in BIG wide open areas alone and for fun. NO! I MEAN NO hand catching this thing with these on! I do recommend them for the RIGHT purposes! Aeronaut CAMcarbon Light Prop for DJI Phantom 2/3, Autel X-Star 9.5 set of 4
