Here it is, the Micro Bone Drone. Have you ever had a quadcopter and thought “Gee, how could I make this less stable?” Well now you can. The roll axis has been shrunk to 9mm to make a near-coaxial quadcopter. Honestly, its probably too skinny, but it does actually fly. If you have some broken whoops or random parts lying around, build one of these. 

Recommended Build:

• 1002/1102 motors (9x9mm pattern)
• 40mm props
• 16x16 stack or 25x25 aio
• ~300mah 1s batteries
• Cam+vtx combo (if your aio doesn't have a vtx)
• Nano ELRS reciever (I have the Radiomaster RP2)
• The knowledge that this is a silly project and likely won't fly all that well

FAQ's:

• Does it actually fly? Yes!
• Does it fly well? Not really.
• Did you iterate on this design? No.
• Should you? Yeah, probably.
• Will you? No, that's way too much brain power to expend on such a silly project.
• Will X part work? Maybe, “work” is incredibly relative here.
• Why is the roll axis so skinny? I drew this very quickly with a specific shape in mind.

• 4 hole motor version (9mm spacing)
• 3 hole motor version (6.6mm spacing)
• Original 16mm only stack version
