3 Hours of flawless flight testing using Stab, Stab Simp & Alt Hold, Try Loiter and Bam, Flyaway.
Well it could have been a lot worse.
I was doing some birds eye view shots of my parents house, Turnigy HAL Frame, converted to coaxial octocopter, 3DR APM2.5+ with the latest software.
Two successful flights before this event.
I should tell you about the only other time I have used a GPS related mode, which was RTL, the HAL came back about 15 deg off course and when it reached the takeoff latitude (or longitude) it seemed to realise it was off course and started to yaw wildly left to right about twice a second, i clicked back to stab and recovered it to a happy landing. That event was about my 3rd flight, I have since done dozens of flights accumulating around 3hrs with this frame and controller.
So this event in particular after the aerial shots I thought I would try loiter, the HAL started to climb up and move away from me, I wasn't too worried and let it carry on to see what would happen, it then seemed to change direction in a hurry and fired back towards the house and tree, in the time it took me to realise and flick back to stab it was too late, unrecoverable, took out a few branches and landed heavily on it's side. amazing to only bend the arms and break two propellers perhaps. images attached.
Attached (I THINK) is the log, I don't understand how to veiw or decipher this, but would appreciate any help in doing so.
NB File 116 is the crash log and the other two a couple of happy flights, well, in 115 it did a crazy yaw on the way down but I put that to my descending too fast. Given the narrow air frame but lots of power it is a bit of a beast to tune.
In case it helps, here is (within a meter or so) where it actually was when I engaged loiter
And it hit the tree about here
