This is a nice, light and sturdy quadcopter frame in the figure X. It fits up to 4.5'' Propellers and weighs 80g (my print). It fits 1806 Motors and is 4mm thick. This does not have the hole in the middle, like the normal X-CAT v2.
Props: up to 4.5 inch Weight: 80g Motor Mount: 1806 Printing Dimensions: 148x148x4mm
