But... in manual mode YOU ARE the pilot, there is not any assist in these mode. You don't have GPS hovering, and all the positioning assistances are deactivated. Full manual meaning that the drift it's produced by the wind, and you are the responsible to correct them.
You don't have any drift in NORMAL and SPORT because these modes are GPS assisted and the drone fix any mispositioning because of the wind. In manual doesn't exist any assist, it's only your drone and your inputs. Nothing else.
No, the gyros should not drift even in manual mode and it has nothing to do with the wind. Without control inputs, they should hold the current attitude of the aircraft for much longer than they currently do. I'm not referring to the active position holding in the GPS assisted modes, or drift over the ground with the airmass, etc.
The behavior is like a slightly out-of-trim helicopter. You can reproduce it even in a hover - put the aircraft in a particular position and then let go of the sticks. Observe the attitude in the goggles - you'll notice the aircraft ever so slowly pitches upward. On one of my drones it also drifts in attitude to the right and to left in yaw. The other drifts in a similar way but not as bad.
Often this is caused by too low of an I-term, but it can also be a problem with the gyros themselves. Though since I'm seeing this on more than one, I figure it's probably just a tuning issue, likely too low of an I-term..... |
