I’m really impressed with your availability and I’m really grateful to you. This is truly a beautiful environment where you can grow thanks to people like you
The configuration is a quadcopter with 900 wheelbase and 16 "propellers and 5.4 pitch (the T-Motor) and about 4.3 Kg without payload (with gimbal and sensors, 6,3Kg)
As for the compass I anticipated your advice and I disabled 1 and 2 leaving only the external 3 of Here v2 GNSS and it’s all much more drivable.
On subsequent flights, using only the external compass, it goes straight and has no particular deviations; we can say that it has changed enormously compared to before.
I had performed the Compass / Motor calibration test and the value was around 30% which seems to me to be normal
But I also thank you for providing me with additional information that for some reason I had left out. Strange the value of 19.8V that frankly I have never entered; the maximum voltage, having 2 10,000mA batteries in 6S-1P is 25.2V but the limit set for the warning is 22.1V and Critical is 21.6V so I don’t understand where the value of 19,8V can be reported
To tell the truth I recently got closer to the PixHawk world so I have not yet developed a great knowledge of all the Mavlink instructions so I rarely go to modify the instructions and I rely only on the graphic part; however this is very interesting
As for the ESCs they are programmable and they are FullPower from 40A … however during the first adjustments they seemed unbalanced but from some flight, after having calibrated them (again), the auto-analysis shows me regular (GOOD) and with imbalance within The standard; I don’t know if this should still involve some action on my part
As for PIDs, they were initially derived from Autotune but then slightly modified; however it is still a temporary calibration but I will try to insert and modify as recommended by you.
One thing I don’t understand is related to the behavior before the Brake … I try to explain myself … when I perform for example a pitch / roll movement, I expect that immediately after the release of the stick, the Quad applies the brake compensating immediately; unfortunately I have a very annoying delay on the brake in the sense that after releasing the stick, the Quad applies the brake after about 1 or 1.5 seconds. So this thing causes a further unwanted travel and at the expense of precision (sevo compensate by hand at the end of each movement)
I don’t know the parameter (if any) to make the brake intervene faster by reducing or canceling this delay between stick and brake release
Thanks again a lot for the info and advice
