"So if there is no stick movements and you have gps 15sats then Aircraft should stop.
It can’t go any faster than 14mph in auto mode, but yet it’s moving at speed up to 28mph, question how can this happen . Wind ( I don’t believe this happened) so the only other way is if Aircraft went into Atti mode."
First I said if Aircraft has 15 sats and No stick movements it should stop. This is correct in this situation ie subject is not moving.
Active track needs gps to hold its position otherwise it will just drift .
The OP was using Active Track in Profile mode to circle clock tower in order to do this he must use roll left or right depending on which way he wants to circle it, he cannot lower or higher his Aircraft in active track unless he exits active track by pressing X.
He lost downlink at 4.37 restored at 4.41 during this period we don’t know what happened simply because no log details.
At 4.42 all of a sudden Aircraft is moving at 20mph to 28mph straight back , my thinking is this in what modes can Aircraft move at such speeds only 2 sport and Atti , 3rd option being offered up is wind well if you look where he was flying he managed to circle clock tower in Profile mode wind having no effect and all the time he was using roll to complete perfect circle, so unless there was a sudden very large gust of wind then wind would not have caused this.
We know he wasn’t in sport mode so this can be ruled out, so for my theory only other mode Aircraft can travel at such speed is Atti mode, so how! We can see in his video what looks like 15 sats but bar graph looks grayed out this would mean he at this time did not have gps, so when you don’t have gps your Aircraft goes into Atti mode and that’s where wind will have most effect. I’m not saying I’m right I’m just trying to work out why and how an his spark suddenly moves from 14mph to 28mph with no input.
And although it doesn’t warn of no gps or going into Atti mode, I was thinking because this movement was so quick and log ends abruptly that warning hadn’t arrive on screen before log ended.
The OP put up 2 videos in the second video cause of this crash in active track was problem with gps/compass I know this because it was posted here when it happened and this Aircraft was in Atti mode. |
