Replacement Arm for DYS 320 Quadcopter
Motor Centers: 12~16mm
I can confirmed that this is the same arms as in the DYS 320.
Quite lucky that I can ordered 4 of this when they were still in stock.
The price could've been cheaper though, but then I remember that the arms are 4mm thick or a lot thicker than the frame itself, so in the end, no complain.
Another wish though, if only they could sell this along with the landing skid, that would be great.
