LiPo Battery 650mAh 11.1V 75C 3S (TATTU used in our paper).BetaFlight will work, but it doesn't offer position hold. The standard INav should also work, but you will need to check if your flight controller is supported.Our INav fork with targets: KAKUTEF7 or CLRACINGF7.(1x) Anyone that can deliver around 15A or 20A per motor to be safe (Spedix IS35 35A used in our paper).

(1x) Holybro Kakute F7 Mini V2 (used in our paper) or Heli-Nation Talon F7 Fusion.

carbon fibre rods or BBQ bamboo skewers with these approximate lengths: 8x 195mm ( 'external cage'), 8x 97mm (arms) and 4x 72mm (legs).įlight Controller (20x20mm mounting holes)

(4x) 1106 3800KV (use with 4025 2 blades propeller, and it will need a bigger frame / longer struts or the experimental motor bases to avoid hitting the RPI or AIY Bonnet).

(4x) 1104 6000KV (use with 3025 2 blades propeller, used in our paper).

The motors shown in the photograph at the top are 1104 ones and the holes are for M2, but be careful with the length of your screws so you don't destroy the motor windings! Bill of Materials (BOM) Brushless Motors and Propellers The central was designed with 20x20mm mounting holes. In the case of bamboo, because they break much more easily than carbon fiber (never managed to break any!), if you glue them it will be annoying to replace.Īll the parts in red are made of flexible TPU 95A.įlight controller and ESC (4-in-1) are mounted between the battery and the central part of the frame (the empty space seeing above). If you get a nice snug-fit between the struts and the TPU parts, you will not need to glue them together. In this case, you will need to glue the struts (carbon fiber or bamboo skewers) or, instead of absorbing the impact, the frame will just fall apart and almost no impact energy will be absorbed by the flexible parts. some holes will change the internal diameter and they may be too loose. Depending on your printer, settings, fillament, etc. The only part that needs support to be printed is the Battery_holder_magnetic_lid.stl. It's a very snug fit! You need to squeeze the round tube-like side, but without damaging it. 3D files (STL) for printing and assembling current and past versions of CogniFly
