I have just a few days of experience with my P4P and so far my flights have been short, low, slow and close by. I've been trying to take it slow and develop a a good feeling for the controls and how the drone reacts.
Earlier today I was wrapping up a very short practice flight, preparing to land I was hovering about 3 feed above a grass area, about to descent, when all of a sudden the thing went hurtling upwards into the branches of a tree! I quickly assumed an RTH had been activated somehow but I for sure didn't activate it. Doing so takes a long press on the RTH button or a click and a swipe on the iPad screen, and I absolutely know that I didn't do either of those things. After a few seconds the drone dropped to the ground ... then a few seconds later hurtled up into the tree again! I was clicking the RTH button to try to cancel, then it fell to the ground again! This time I grabbed hold of it - just in time before it tried to ascend for a third time! So now I've got my controller in one hand, and a drone at full throttle in the other - apparently not responding to commands on the controller. I tried everything I could think of but in deperation resorted to pulling out the battery. Nothing else seemed to make a difference.
According to the manual there are three reasons for an RTH:
- Smart RTH (I didn't do that)
- Low battery RTH (nope)
- Failsafe RTH (I was less than 10 feet away!)
I realized that I could play back the fight in the flight log, and sure enough when I do so I see a messae pop up in the upper left corner saying "Tips: Return to home initiated" and the text at the upper left changes from "GPS" to "GoHome". This happens twice within a few seconds, just as I described earlier. Other things of note at the time the RTH are:
- Flight mode: GPS (P) with a good GPS signal (14 satellites)
- Battery level 64%
- Height: 3.3 feet
- Horizontal speed: 0.0
- Elapsed flight time: 3:34
- Remaining flight time: 15:57
I have been going over this in my mind all evening and I just can't figure out what went wrong. Has anyone else out there experienced this, or can anyone suggest what may have gone wrong?
By the way, I did learn a valuable lesson ... don't at any time be underneath the branches of a tree, or anything else for that matter! Thankfully, despite falling out of a tree from maybe 12 feet a couple of times, no aparent damage was done.
