Hey there,
I can fly my drone successfully in mission mode. I would like suggestions to improve my build based on the log data.
This is my build:
- Frame: S500 quad
- Flight Controller: Pixhawk 6X
- Motors: Tmotor MN3110 KV700
- Esc: Tmotor Air 40A
- Propellers: 12x4.5
- Battery 3S 2200 mAh
- Weight: 1.580 kgs
I’ve mounted the flight controller on a anti-vibration shock absorber plate.
These are some of my observations and queries:
- Are the vibration levels optimal for an S500 frame, or should they be lower?
- The Roll/Pitch/Yaw angular rate graphs don’t seem right. What could be the issue?
- The motor outputs appear to be saturated. I set the PWM_MAIN_MAX values to 2000, MPC_THR_MIN to 8%, and MPC_THR_HOVER to 50%. According to the T-Motor datasheet, it can produce 500g of thrust at 65% throttle, which should be sufficient to lift the 1.5kg drone. Is the saturation due to wind?
- There is some overlap in the raw acceleration graph between XY & Z axis. What could be the issue?
- Are there any other issues in the logs that I should pay attention to?

These are the PID values after Auto Tuning. I had performed this earlier in HOLD mode.
