M250 Moskito Racer Drone

thingiverse

This is a beta version of a quadcopter with a square base that measures 250mm diagonally. It's designed to hold 1806 and 2204 brushless motors (I used 2300Kv in 3S for mine), which have 4 and 2 screws, respectively. The space allotted for the flight controller is 30.5mm, making it compatible with CC3D and Naze 32 boards. For arm reinforcement, you can use 6mm carbon tube (found in arrow shafts at sports stores) or glass fiber kite arms (I used fiberglass rod). My version was printed using NGen, a material equivalent to ABS supplied by ColorFabb. It's lightweight, flexible, and prints well without a heated bed, requiring some brim. The frame is designed for M3 screws that are 42mm long (I used cut and filed threaded rods) and M3 spacers (nylon spacers worked fine for both the flight controller and power supply). I stuck adhesive velcro on top to hold the LiPo battery and radio receiver in place. It was drawn with FreeCAD 0.15, and the files are available for modification. A camera support hasn't been designed yet; you can always use gaffer-tape as a workaround.
