Hi all.
I am quite new to PX4, and have not used Ardupilot either - I am now building 2 drones that will be running PX4, but I am a bit in doubt about tuning the 2 drones. 1 is a S500 frame and another is a custom 5 inch frame.
I can find a lot of guides for tuning different parameter of PX4, but not in which order. And another question - Which parameters can you guess / estimate beforehand to optimize for your first flight?
These question came as basis of me building the S500 frame with a Pixhawk 6C and attatching a 6S1P battery with some 900KV motors - First time I tried to take off with default values, it went very high first time in altitude mode since the MPC_THR_HOVER at default 50% was waaay too much.
So MPC_THR_HOVER I assume I could have guessed should be lower based on the 6S battery / 900KV motors, but which other parameters can I already guess and assume based on frames, batteries, motors, propellers? Right now my drone is shaking it self apart from vibrations and the motors gets hot, and I can read that the motor filters should be calibrated, but that is after calibrating PID?
So which calibrations should be done in which order? My current guess:
(1) Sensor calibration (Accelerometer, Gyro, magnetometer)
(2) Minimum / Maximum PWM for ESC
(3) ESC calibration (in the power tab)
(4) Pre-flight test tuning
(5) PID auto calibration
(6)MC Filter Tuning
(7) ? Any more ?
For those asking about logs from the first flights:
