I use these in my quadrocopter - 4 * DT750 and 2*1147 2*R1147. Thrust is pretty enough to carry about 1.6 kg.
Quality isn't perfect, not well balanced, but seem to be usable.
Sharp edges, I accidentally cut myself while motor was not running:(

They're really cheap, but also a lot of work to balance. Out of 10 props, just one was close with the hub, the other 9 were massively unbalanced. Blades all needed some work.
