Replacement Propellers for X6 Nano Quadcopter, Estes Proto X, Cheerson CX-10 Rotor Blade Set (Black and White)

Regarding a Cheerson CX-10....A lot of complaints about not fitting the protoX but I'm here to say for me on my CX-10, these rock.Fit: The prop pitch, size and fitment was spot on, they fit the shaft snug, not too tight where you have to force it on, and not loose. So...fitment is a 5 star.Construction: I plan on doing a video on the construction on these blades. They have extra support gussets along the underside that makes them I'd think at least 75% stiffer. The plastic feels a little stiffer as well. These are stonger, and Ive yet to break any.Performance: The Quad did not loose agility or performance, I cant say that it gained any, but it sure did not loose any.But what I DID notice as an improvement was its sound. These blades are just a bit quieter. Soon as a I took off it was a pleasant surprise that they were quiter and being so rigid, it was so smooth.Con: Only real noticable con that gave it 4 stars vs 5 was after a day of flying these around on 3 different CX-10's the batter does drain a little faster, maybe from the extra weight of the blades with the gusseting, I haven't weighed these compared to stock but Im guessing the extra weight spinning is draining them a little faster. Maybe about 2 minutes of flight time loss or so.Overall: These rock, and I see these as a performance "upgrade" blade from stock for a CX-10

Got these for my 2 Estes Proto X SLT mini quads. These are tighter fitting so it's not a garage sale of propellers every time you hit something. The bad side of that is that they seem to break a lot easier. I'm not terrible at flying but I use it to tease my dog and sometimes he wins. The numbering system is backwards but if you have half a brain, you can figure it out by what way they spin. I use a little flat head screw driver to pry the propellers off when I break them. They're definitely not as forgiving as the ones that came with it.

Pay attention to the debate about whether or not they work with the Proto X/Syncro nano copters. Yes, they do, BUT here is the deal: They are indeed shorter in the stem than the original blades, something that really should be noted in the description. Do they work? Yes, but only under perfect conditions and when care is taken to assure that the blades aren't rubbing on the copter body. If the blades are pushed down too far or get bent slightly downward after a few bumps or crashes, the rubbing problem occurs. Why they make the so short is a mystery.

Alright These props could be the best constructed I have seen but they are a little to solid and do snap easy at the base when messing up on tricks. As well they are not for the Estes Syncro but will work. I have them on it right now and they sit a little low and do hit the cage around the battery and receiver. If you don't press them all the way though it is fine and they will still stay tight and you will not lose any control. All in all it is a good blade and I couldn't knock it for the fact that they are reasonably priced and work well enough.

I replaced my Estes mini drone props with these and it didn't fly. Swapped colors to make sure - didn't work. Put originals back on - it flies.Update - black and white blades are deceiving - black goes to front - but it matters what side of front - make sure pitch is right..

They are a little bit thicker which means they weigh slightly more and they are also stamped backwards as in the one stamped A goes on the B motor on the Proto-X but so far they have been decent. I will say I prefer the stock blades but at this price I am fine buying these instead of $3 a set.

Item's need a bit of force to get back on the motor. It almost felt like i was going to break it. When I finally go them on they work great. They are a hair shorter than the stock propellers the drone came with but nothing noticeable in flight.

Worked well enough but it should be noted that they are different from the stock ProtoX blades (at least the blades which came on my Proto).I found changing over to these from the stock units 2 at a timed worked well (change opposite corners).
