Black 10x4.5 Propeller Set x2 for Multi Rotor Drones by Master Airscrew

If you looking for the best props these are it.

Props run smooth and tips track true. My flight time increased with these props about 10%. Props feel very plastic and are very lightweight. Not sure about durability. 3 of the 4 props required balancing. Flying on a DJI Flamewheel Quad nightflyer and climb and cruise are perfect on 3S.

Excellent

I got these for my foam airplane final project for science. The teacher had dinky little 6 inch props, but said if we bring our own in, we could have any size we want. And, since my plane was the second largest out of all his classes, i knew i needed a bigger propellor. So, i bought this. It generates a LOT of lift. Not too much flex either. My first propeller snapped in half because i accidentally set it to full throttle while holding it and it flew into the edge of a table. The second one broke after the plane stayed in the air for about 6 seconds(best out of everyone in my class). That being said 10/10 would recommend

Built my own drone and these worked great on it. No issues at all and was an easy install Haven’t broke any yet

The propellers themselves look good, but there were no prop adapters in the package.

I have been using Master Airscrew props for a very long time. they are my standard so when it came time to put some on the quad copter they were my first choice. perform great and very quiet

Was hoping with the hefty additional cost of these propellers they might be balanced out of the box. That was a bad assumption on my part. Will balance and then do a test flight...more to come. So far they just seem like overpriced plastic propellers.
