DEAR
My hexa copter using sunny sky 880 motors and pixhawk autopilot with latest firmware and analog maxbotic range finder sensor, with PID defaults.
As i am new and done all setting in mission planner of altitude hold,
As i have went for test the flight after my take off when about 3 meters i have done altitue hold active, my copter flew vertically like rocket very high, suddenly i reduced the throttle stick and my copter fell on my roof top and i has crash and broken 2 arm of hexa copter
Had a quick look at your log and noticed a few things.
Your battery failsafe triggered long before you switched to AltHold and your battery voltage was already at 9.2V.
The throttle was above 1500 (mid point) and so the copter went up as commanded until it did not have enough power left to keep stability.
Your vibrations are quite high which also tends to cause this effect, so it certainly didn’t help.
Solutions:
Make sure your battery is fully charged and up to the task.
Heed Failsafe warnings.
Set your throttle mid parameter.
1)my battery is New 3s 7000mah 45c still battery pixhawk indicates battery
low every time within a minute of hover. why ?
2)WHAT Heed Failsafe warnings. AND ITS SETTING WHERE IT IS DONE IN MISSION
PLANNER
what are its effect? please.
3)If i had to put my hexa copter to postion hold what all setting need to
be done
as of now i had fixed the GPS and my drone is flying with the help of your
graph and points guided
please do help in clearing this position hold
please do guide me that if I had to fly or restrict my copter in height
only within 3 meters or 5 meters maximum, it should not go behond that
height, then what need setting to be done
thanking you
regards
william
