M4 strange behaviour
Posted: Sun Mar 27, 2016 11:25 amHello,
I recently damaged my AQ6 and replaced it with an m4. All went well in the build and everything seemed good, i loaded up the same pids as i had been using with the AQ6.
I had completed three flights with no major problems. I had had some issues with my Hacc & Vacc jumping around a bit , but i put this down to flying in a a deep valley.
The problems occurred on the second half of my third flight, It started to sort have a few glitches on the yaw axis, so i decided to land. As i was positioning for touch down, just a few centimetres from the ground, she suddenly tilted forward and tried to fly off! At that point i immediately shut down power. The result was a couple of broken props and a hard landing.
I am totally at a loss to why she tilted forward. I was in manual mode. It was as if i was in position hold with low Hacc and Vacc and she was trying to reposition.
I have looked at the logs and can see that my vibration on the z axis has increased since the first flight i did the day before, But i don;t think this would have the effect that i suffered.
I would like to upload the log, but it is close to 30KB and there is a limit of 5KB here. How is everyone else doing it.?
Any help working out why this happened would be very much appreciated...
