Quadcopter Drone

thingiverse

Updates - 1/01/2018 Added landing gear to shield batteries and eventually camera from hard landings. If you strap batteries to the top of the drone, this won't be as big of an issue. The landing gear consists of four 3" long 3/16" bolts (sorry for using imperial units, I wanted to use M5 but this was all I could find). Attached to the base of these bolts is a front spring, back spring and two side springs. They are designed to absorb some shock if the drone lands at an angle, and will prevent too much torque from being applied to the arms. These springs will break easily, but they only take 20 minutes to print, and prevent other more important things from breaking. Added some vents below the motor mounts to prevent overheating. This is very crucial! Without these vents the motors will quickly fail. Thickened some areas on the body which were breaking too easily. Listed below are all the parts I used. I'm pretty new to quadcopters, but it seems like most of the mounts used for flight controllers, PDB's, ESC's, motors etc. are pretty standard, so if you want to use different parts they should still work fine. - 4x Racerstar Racing Edition 2205 BR2205 2300KV 2-4S Brushless Motor - Racerstar RS20Ax4 20A 4 in 1 Blheli_S Opto ESC 2-4S - F3 Flight Controller Acro 6 DOF - Matek Systems PDB-XT60 W/ BEC 5V & 12V 2oz Copper - FlySky FS-i6 2.4G 6CH AFHDS RC Transmitter With FS-iA6B Receiver - 4x 5 inch propellers - 31x M3 bolts (most of these came with the parts listed above) - 15x M3 nuts The arms of this quad were printed in ABS and the body was printed in PLA. Everything was printed with 100% infill. Some time in the future I'll be adding a camera mount.
