First crash

[tomeaton]

Went to take off this morning, as I was taking off the controller stopped responding and the drone flew straight up into tree branches about 20 foot up. When it eventually fell out of the tree it landed on concrete and broke both front arms. The gimbal now fails to respond properly as well. Am absolutely gutted, and frustrated that the controller stopped responding so I couldn't fly forward.

sorry to hear that.
Looks like that the signal lost triggered drone's return home function.

It has only taken off a second before. Any ideas why the controller would disconnect like that? Full battery on both devices. I was standing about 4 ft away from the drone, next to a field, no power lines etc nearby

Uploaded the log file, no data found by the tool. Raw dump is here:

Most likely magnetic interference. When you download your file sar104 or meta4 can confirm if they are around.

Being that close to him it would not have ascended.

lateral proximity to the pilot should not be a factor unless you have home point set to dynamic though?

is it possible that there wan't a good GPS lock and home point set before takeoff?

I don't take off until I get a GPS lock, what was odd was that the drone stopped responding to the controller and just kept climbing.

Lateral proximity is absolutely a factor???

That's the file I converted to txt log and put on pastebin (see post above)

oh sorry! I'm on about the DAT from the aircraft or the tablet not the .TXT

Home point looks recorded

15.006 : 527 [L-HOME]First. lati:51.0614938 longti:-2.0209004 alti:152.75

But just before the assisted takeoff there is a failure

19.488 : 751 [L-FDI]start_act_seq_example failed, ret:0|
20.988 : 826 [L-RC]rc cmd:STD_ASSI_TAKEOFF

...which @sar104 or @Meta4 may be able to decipher!

The extracted txt log is interesting but I'd need to see the full DAT file.

lateral proximity to the pilot.

 

[Simmo]

lateral proximity to the pilot.

Yeah?? Generally the operator would be standing at or near the homepoint?

 

[caspian]

that's an assumption you are making. the aircraft has no idea where the pilot is unless dynamic RTH mode is selected, all it knows is the static home point.

So got a quote back from drone doctor today, £591!!!!

I only paid 620 for the drone in the first place, so that's a no go unfortunately.
