Hello guys.
in my case,
my Quad(motor to motor : 900mm class) has CUAV Nora FC,
16000mAh 12S batt’,
and 5015 150KV motors.
but there is little problem. I don’t know about exact specifications of the ESC. it just 40A.
The distributor said, it is FOC type and that type has not necessary ESC calibration.(honestly, i can not understand what that means)
anyway,
I flashed firmware Arducopter 4.1.0 for Nora in mission planner.
so i setted basic config.(Frame, sensors, radio etc.)
it flies very well in stablize, althold and loiter modes. there’s no fluttering.
but i have to use QGC. so i flashed PX4 firmware(1.12.3 CUAV Nora default) in QGC, and flying attitude is so weird.
in all modes(stab’, alt’, loit’) Quad is vibrating irregularly.
Even with PID tuning, the vibration did not go away.
personally ardupilot firmware its very stable… px4 firmware its a little bit raw and if you want tune it well you need perform a good calibration changing and testing the parameters.
Thanks for your comments.
i’m running copter on QGC latest version(4.1.4)
and i made pretty good flying today. i tuned attitude control, horizontal velocity, PID etc.
honestly, i don’t understand which parameters are makes fly better.
Tomorrow, i’ll upload log data. please check and share me your opinion. it will be very helpful to me.
Thank you all!!
