Hi guys, I need your experience to have a quick look of the parts im about to order.
I need your help to find a decent Flight controller the can communicate with ArduPilot mission planner, and my Raspberry Pi 4B / 5.
Pixhawk is too expensive. I need something that is reliable and supported for much cheaper. I don't mind soldering myself.

Drone parts so far (*note that communication & control via RPi & SIM 4G Hat):
  1. Frame - HAWK’S WORK F450 Drone Frame, 450mm
  2. Motors - HAWK'S WORK A2212 Brushless Motor 920KV (https://www.amazon.com/gp/product/B0CDGNGLHM/ref=ewc_pr_img_2?smid=A2Z91JXWPM95ID&th=1)
  3. ECS - HAWK'S WORK Brushless ESC 20A
  4. Propellers - 9450 Self Tightening. *Note - I assume that bigger propellers are more efficient (https://www.amazon.com/gp/product/B07CP5DZ5N/ref=ewc_pr_img_1?smid=A35WWLOP9AYMPW&psc=1)
  5. Companion computer - RPi 4B
  6. Communication & GPS - Waveshare SIM7600G-H 4G HAT (https://www.waveshare.com/sim7600g-h-4g-hat-b.htm)
  7. Battery - 11.1V Lipo Battery 4200mAh 3S 25C - TX60 plug.
  8. Power Distribution - I think it part of the frame
 
I'm looking for a cheap fpv controller too unfortunately my favorite online store stopped selling the f3 boards for $7 so cheap building is no longer an option.
