Hi all,
I am not proficient with the language of telemetry so I will just tell the story and hope that you understand the question I am asking.
Sometimes, my fellow drone pilots complain that their drones "drifted" and thus crashed with no sticks control. Whilst majority of the crashes are confirmed pilot error after reviewing the telemetry, I wish to dig further into the problem to see if incorrect sensitivity setting in the remote controller would contribute to the "drifting" phenomenon.
For most DJI drones, it comes with 3 standard control mode: Sport mode, Normal (aka P mode), Tripod (aka Cine mode etc). They each has default maximum ascend/descend speed, horizonal speed limit and rate of turn (angular velocity) etc. However, the setting can be adjusted in the “Gain & Expo Tuning”.
I have conducted several test flight (with Mini 3Pro) in different settings and did find that the drone may "drift" in some situation, especially when the “Yaw Smoothness” and “Brake Sensitivity” are adjusted, e.g.: when I do a full pitch followed by immediate release to neutral stick with a low Brake Sensitivity setting (value: 0), the drone will "drift" for 3-4 second before a complete stop in air (i.e. continue forward flying for about 15 meter); whilst if the Brake Sensitivity setting is set to high (150), the drone will stop almost immediately with a more drastic nose tilt. Similarly, with inappropriate Yaw Smoothness setting, the drone may continue to yaw after hands off the sticks.
Back home, I examine the dat and txt of the test flights. I found that the 4 relevant telemetry (RC.aileron, RC.elevator, RC.throttle, RC.rudder) were only showing how much I moved my stick (range: 364-1684, return value at 1024, regardless of the mode or sensitivity setting). Likewise, the mode (RC.mode) also only show if I was in N mode or S mode.
My theory is that if the sensitivity setting of respective mode is adjusted, it should somehow be kept/ reflected in the telemetry/somewhere. I just don't know where to find.
Does any one knows where/how to find related record? May be they are just kept for some models but not the others?
Thank you.
P.S. In case I did not explain myself clear in the above, this clips showed almost exactly what I tried to do in the test flight
