First let me say thank you, I've been a Pixhawk user for several years and think the work of the FC. This is my first HEX build so obviously I put a Pixhawk 2.1 inside.
This is the first flight of a new build, one which I had trouble configuring the 30amp ESC's and originally loaded CHIBIOS build on the PC trying to use pass through connection for ESC's...which did not work.
So, I loaded APM back on the board... I HOPE there are no negative values left over from this????
So the first flight was VERY twitchy and Unstable.. lasting just over 3 minutes..
First(First issue), I've had issues with the Safety switch seemingly doing nothing .. It will not arm the copter..
I have no messages within mission planner as no pre-flight checks look to have failed....
So I change BRD_SAFTYENABLE = 0 and All motors spin, ARM and looks good.
Second (Second issue) ON takoff the EKF2 IMU immediately re-calibrates as the Copter veers left....
Once that in-flight calibration complete, the HEX settles down...Trim seems good but slightly off... Pulls to the left at a constant rate..(I dont think this is CG but correct me if I'm wrong)
Third (Third issue) IMU keeps re-calibrating and adjusting YAW mid flight at a constant rate.. How do I stop this and why is it happening?
Forth (Forth issue) LittleBee 30Amp ESC with APM set at 2 = Oneshot125... These ESC's auto detect but the CHIBIOS build says option 3 = DSHOT however, I dont see that value in Mission Planner.. Could this instability be caused by incorrect ESC signaling ?
The main focus is Stability, the flight was VERY unstable , so much you see at the end I just about lost it on landing, flight seemed to be getting worse
I'm attached the Tlog hopping someone could offer some insights, at 84% of the log is where the actual flight begins..
Many thanks in advance
