Any ideas what might cause something like this? I have a 250 quad that I've been flying around for a bunch of months at the same field. I haven't made any changes (software or hardware) and suddenly the quad crashes every time I fly it. I took a look at the log and it looks like the commanded roll, pitch, yaw, and throttle all go to 0 and it just falls, as you'd expect. I've attached the log, you can see the commands drop around 2153.0. Screenshot also attached.
I don't see a radio failsafe, but it seems like there's a GPS error that happens every time (but according to the plot I see it after the crash - is there a time delay in displaying those red flags?). Could be due to the crash though as it lays sideways or whatever on the ground.
I've repeated this 4 times in a row already. The strange thing is I can fly inside just fine. Could it be 2.4 GHz interference? I'm using an HK Orange DSM RX and TX.
Thanks for any ideas
