DAL 6040.
First the good points.
They have good power.
The rest I'm afraid is bad.
They a so badly balanced, to be almost impossible to fix.
I did a test on one, and had to cut off 2mm from one tip to balance it out
But the worst thing is, they a super brittle, and far from being indestructible.
They are so fragile, porcelain props would be more durable
So first flight went ok. no issues. liked the power.
But the second flight ended abruptly with one prop shedding both blades when it sheared at the root
I checked in the video, and playing frame by frame, you can see the blades flying off.
So first impressions are, not a good buy, even if they are cheap.
The one with no blades sheared in mid air. The other tow broke on impact from two feet up in a hover.
