Dont fit to 2mm motor shaft. I guess it is more a 2.3mm.

It is a plastic spinner. The hole for the motor shaft is also plastic. doesnt fit on 2mm motor shaft. there is too much play. I think its more for a 2.3mm motor shaft. No Grub screw/screw included to mount the spinner on the motor shaft. There is a hole prepared for the mounting screw, but you have to drill it completely thru the hub.

Mine came with steel blade pins that were quite sturdy. For the arrester screw I drilled a 2.4mm hole all the way and cut a 3mm thread, so I could use 2 decent clamp screws in a balance way. Grub screws brake the plastic. My problem was drilling the shaft hole to size (3mm). With the plastic so soft it is HARD to drill straight enough for a properly centred hole. Lose precision and your prop is more like a vibrator! However, the price being so low you can use the blades on any other hub that has a 6mm shoulder and still save. The one I got working did not self destruct at 16000rpm, not sure about in the long run :) Good value for the money if it works for you.

Seem to be "ok" quality however you cannot remove the propeller arms so cant fit as a pusher configuration, for a delta wing (x5 in my case) for example.
