Spring is just started, but it’s still cold out there. After I tuned XJ470 APM copter, I took a video at the airfield near my house.
This is my final tuned PID parameters. I tested with both 1038 and 1238 propeller, and finally decided to go 1238 propeller:
This is the video what I took:
The overall flight time was more than 16 minutes and hovering time was 22 minutes with carrying camera gimbal using 4s 5200mah 10c lipo. It was outstanding.
