I want to make my quad more stable. The idea is to set everything up the best way possible and then use the Ardupilot board.
I am using a GAUI GU344 triaxial gyro for now. The distance between opposite motors is 120 cm (47 inches). It's total weight is 5 pounds (quite heavy, since I'm using a 400 grams battery per motor)
The 60A ESC's are set to the lowest advance timing (1/5) and a start up range of a second, being the standard a timing of 3/5 and a start up range of 0.25 second.
The propellers are APC 12X6, and no matter how much I try, the quad is never dead stable and it always feels really sensitive. It also changes angles weirdly, not really listening to me. I use dual rates, exponentials... It never feels right. The 'gain' on the GU344 is set really low, if i increase it, it wobbles. the frame i built as exact and precise possible and the angle of the motors is zeroed out.
Can anyone tell me what I am doing wrong? Any wild guess will be appreciated.
