FPV Quadcopter 250 V2.5

This is my latest version of my completely 3d-printable 250 FPV racing quadcopter design. The design is very compact and is designed to not break. The control board, RC receiver, power distribution, and other things are within the 15mm between the top and bottom plates, so they are completely protected. This quadcopter is designed to be robust and reliable, even in the hardest of crashes. The arms are foldable, to increase time of impact in a crash in order to keep them from breaking. The landing gear acts as a fuse, it is likely to break in a hard crash, but also helps prevent arms and other parts from breaking, while being very easy to replace. The battery can be mounted on the top or the bottom; the battery mount part is only needed for the bottom. There is an extended version of the top plate used for mounting an FPV camera from the bottom in front. A Mobius or similar camera can be mounted on the top or bottom in addition to the FPV camera. The motor mounts have standard 12X16 mou
