No ... none of those are relevant
As indicated, I am already aware of the things you mention, yes it would show in the logs IF connection was not lost prior to that packet being transmitted.
Obviously we know it crashed and the logs say nothing. Therefore
something happened.
Just because the logs “normally” catch such events does not in and of itself mean that such events will always be transmitted properly.
5/100ths of a volt ... not enough to cause any concern.
Yes I agree that such a small value in and of itself is not a direct cause for concern.
However, the battery voltage is polled once per second. In the intervening time there is usually telemetry data sent every fifth of a second.
The small but sudden voltage change is shown only on one single telemetry line, then it goes dark.
This means that something happened from the batt poll time and 200ms later, which in any event would not read differently until the batt was polled on the next second.
200ms is enough time for a voltage spike, of which only the start was caught by the battery poll just prior to losing connection.
Drone was well above any potential obstacles
Were you there? I might have missed something in this thread.
I've seen trees that are easily mid judged as to how tall they really are, especially at evening/night.
I learned
THAT lesson my first week of flying the drone.
and any collision would show in the flight data.
If the drone was operating properly and nothing caused a power off event before such telemetry was able to be sent.
But I am operating on the premise that the drone was not operating properly, because 200 feet with no buildings and sparse trees is rather short for a loss of connection event.
Data shows no hint of a collision. It just stops.
Sport mode shuts off obstacle avoidance, so there may not be a “hint” until the motors jam.
That said there is a little hint in the excel file, I’ll upload the screenshot in another message.
People fly in Sport Mode all the time without issues.
That’s a logical fallacy. People drive all the time without seatbelts without dying. That doesn’t make seatbelts superfluous.
Sure, DJIs are impressively good, yet still here we have a missing drone, and others have had flyaway or dive into water or any number of other events—I am not saying that sport is bad, but I do know I overloaded my Mini
3pro in sport mode on a calm evening, so I know the current draw is close to limits.
Operating a machine close to limits AND experiencing an anomaly can equal a sad outcome.
Any of that would show very clearly in the flight data.
Only if there was data available to put into the telemetry, and that was done prior to disconnection. Though on that front I’m going to post another message with a screenshot of the excel file in a moment…
But again, sport mode disables obstacle avoidance.
