Hello to all !
Even if already discussed somewhere I’d like to ask a question that seems very important to me.
I am going to maiden a big x8. TOW around 15 kg.
Foxtech D130 X8
KDE 5215 (435 kV) motors with triple blade 17" props
Herkules III okto XL ESC board (400 Hz, also set in PH)
Pixhawk 2 on copter 3.5 rc5
mission planner latest beta
TX/RX JETI DC16 on SBUS
motor min/max pwm according to manufacturer set to 1100-1900
modes preset are stabilize, alt hold and loiter on 3pos switch
rate roll/pitch kP on poti ch6, ( limits set to 0.08/0.2 )
in extended tuning ALL values default (4.500 … 0.135 … etc)
Throttle mid is on learn and save ( however that exactly works, could find precise description (for a newbie to PH ))
data log is extended to IMU also for the vibration issues
And now my question :
One of my buddies (flying similar machines) told me to simply lift off with all values on default. It should fly.
But being new to pixhawk I would like to run autotune when everything seems ok. Is there any risk on this
concerning that we are talking about a big bird ? Or should I preset some filters / values on which I don’t have
enough experience yet ?
And should I, prior to flying, set the (separate) level in acc calibration ?
Any hint could be very helpful and is very much appreciated.
Many thanks in advance,
