nice frame and very light weight. it has a 20mm x 20mm mounting but the standoffs for the top plate are very close which means, that not all ESC or FC might fit on this frame. my 4in1 ESC first doesn't fit.

very happy with product comes with silicon battery mat and landing take off foam pads and battery plate to protect battery. and inflexible for the sharp edges. the frame does flex but not to much. overall very happy would buy more. and also a good price to pay. had to wait nearly a month to receive it
