Micro 107 Noob-Copter

thingiverse

Let it be noted in advance: I am far better at CAD and 3D printing than at flying and understanding quadcopters. My first steps into quadcopter tech were closely followed to punkkill's thing description http://www.thingiverse.com/thing:1221911 and his great instructable. However, as I soon discovered, building quadcopters is the easy part. My indoor maiden flight ended badly, and worse than expected. After trying out prop guards (not suitable for real crashes) and even a quadcopter design that protects propeller blades, the Mini Whoop, http://www.thingiverse.com/thing:1715901 (too weak frame for the kind of crashes I seem to enjoy), I decided to design my own as-crash-resistant-as-possible and indoor-capable beginner's quadcopter frame. I present to you the NOOBCOPTER - 55g without battery, but with well-protected props and motors and a closely fitting flight controller mount. This thing is designed to be used with ladybird props, Hubsan X4 (or any other 8.5x20mm) motors and the Micro Scisky flight controller. I use 1s 500mAh 25c batteries. You will need 1 frame, 1 top part, and 2 guards, and 4 M3x12+mm screws & dies. Glue some padding (e.g. evazote foam) to the motor mounts for better absorbing shocks if you printed the frame with PLA. Noobs shouldn't fly with FPV, so my frame does not come with a camera mount. If you really need one, you could design a new top based on the camera mount design of your liking - my frame should be compatible with other designs based on punkkill's model. Punkkill's model and also the tiny whoop are, due to their weight and moment of inertia, much more agile than my flying tank. Nonetheless it will smash into a wall when you try rate mode first time... and survive. Update 25.11.2016: New frame version 2.2 with lighter and deeper motor mounts, and I added a new picture of the quadcopter. Update 28.11.2016: Also uploaded top and guard version 2.2 - only small changes: Even tighter fit for the micro scisky flight controller Countersunk screws (you shouldn't be able to scratch your walls with the screws anymore) Simpler guards (in terms of symmetry), easier to mount correctly. Update 11.1.2017: New version 3.0 +++ The micro scisky flight controller now snaps into the lower frame. You could fly the copter with the frame part only, no screws or glue needed. ++ Lower frame is stiffer and should survive more crashes than version 2 ++ The copter is slightly lighter, and has a noticeably lower moment of inertia Simpler top part; you should probably be able to substitute it with any other punkkills-compatible top part (e.g. one that features a cam holder) Lighter prop guards; now one part per rotor. I found this working best, especially when the frame is slightly warped. The frame and prop guards are compatible to older versions Note 21.9.2018: I made a new Remix for the SP-RACING-F3-EVO-Brush-Flight-Controller https://www.thingiverse.com/thing:3113259 Print Settings Printer Brand: Ultimaker Printer: Ultimaker 2 Rafts: No Supports: Doesn't Matter Resolution: 0.2 Infill: 100% Notes: Wall Thickness: 1.6mm! The wall layer is supposed to tolerate more beating than the filled-in areas, even with 100% infill. I don't need support on my machine.
