Thank you for the insights, but I am still wondering why it would fly away without any pilot input? For any type of system malfunction, shouldn't it either hover or fall down rather fly away in extreme high speed. It could have seriously injure some one.
Hi,
To keep a drone in a steady hover it need 2 type of data ; GPS and Compass.
Try to make it clear for you.
- Put your drone in front of you at a table, camera facing you, its is flying there...
- Push it backwards, away from you, push back was the wind....
- Position drone is changed (GPS data), need to go forward to correct position
- Knowing the correct compass heading ; it now know wich motors to give more power to fly fwd
- BUT now assume that compass drone is 90 degrees offset to the real heading at your table (camera still facing you)
- push it back again
- to correct it back to the original position other motors get more power., now its flying 90 off the push back position, needs more correction, more power, etc etc = fly away
That is why the MOST important check for DJI drones is to check compass before takeoff !
cheers
