Experimental Multirotor

thingiverse

An experimental design for a three-prop multirotor aircraft is currently in development. Plans are underway to assemble and test this prototype, with detailed information being made available online for the purpose of scientific research. All STL files have been provided in random orientations; if printing before finalization occurs, users should exercise their best judgment regarding rotation adjustments. Upon completion, the STLs will be reoriented for optimal print settings. This design revolves around 2212 brushless motors, 8-12 inch props, and a Futaba S3003 size servo for rear vector steering. Electronics options include MultiWii on a Nano dev board paired with an external MPU6050/9250 and Ublox 6M GPS. A 30x30mm M3 mounting location has been added to the electronics box to accommodate F3 FC boards, as well as space for a radio module. Above the lower battery deck is a mounting point for power distribution boards like PDB-XT60, with pre-drilled holes for routing power wires and current flow. Given estimated weights from electronics and batteries, along with Cura's 30% infill projection, this aircraft may be capable of flight with approximately one kilogram total weight. Assembling the design requires M3 hardware; users can opt to secure arms with hot insert knurled nuts and M3x6 bolts, but a stronger setup involves long (25+mm) M3 bolt and nut combinations. For maximum stability, 15 M3x25 and four M3x30 bolts would be necessary. However, shorter M3x6-10 bolts can secure the landing gear and electronics.
