Iris F154 is a carbon frame designed for building lightweight and agile 3.5″ and 3″ toothpick drones. The frame is designed for AIO boards with a mounting hole spacing of 25.5×25.5 mm and motors with mounting holes of 9 mm M2.
The frame consists of four arms, two plates, and fasteners. The thickness of the arms is 3 mm for good durability, and the thickness of the middle plates is 1.5 mm. The total weight of the frame is 18.6 g. The frame has a diagonal motor distance of 154 mm. There are cutouts in the bottom plate for routing the strap for battery attachment. The edges of the arms are chamfered for increased durability and a smooth surface.
The package includes only the carbon part without the canopy. Thanks to standard mounting holes, the frame is compatible with a wide range of canopies available for 3D printing.
