Features:
- 70% frame are 3d printed
- Simply assembly
- built for a single 3S or 4S battery at the center of rotation/thrust, with room for a 6000mah 3S or 5200mah 4S battery.
- ESC are mounted underneath the motor.
- Simple cable routing.
- The drone weight goes up to 1.2 Kg including camera, ESC, FC, GPS, Emax 920kv motor.
3D Design
Except for the carbon fibre tube, which is 3d manufactured using ABS material, this is my suggested Fusion 360 design.
Parts Required:
- 4 x Emax 920 kv Motor
- 1 x 4 in 1 one Electronic Speed Controller
- Matek F405 FC
- UBLOX Neo 8m GPS
- 1 x 3s 5200 mAH Battery
- 4 x 10 inch self tightening Propeller
- Turnigy 6ch receiver IBUS protocole
- FPV Camera Tx and Rx
- 915Mhz Telemetry
Software:
- INAV GUI
- UBLOX center
- Blackbox data viewer
After assembly
After assembly and a test flight, I can conclude that flying performance is poor and the design is ineffective since it cannot withstand wind-induced turbulence. It works OK with a few PID tweaks, but it still has to be fine-tuned for smooth flight. I have attached a video below.
Test Flight:
End of experiment
Result: Pass
