As I am a newbee at this forum a quick introduction.
I am Erik, and since I bought a Parrot AR Drone last year, I decided to upgrade to the real stuff, after a flyaway of the Parrot… (Never recovered the drone)
This weekend I had selected for a maiden flight of my RcTimer Spider with a Pixhawk controller, running Arducopter v3.1.2
After a solid takeoff, and a very sensitive throttle response, the quad was almost lost just after a left turn (Yaw), which are acting very aggressive (So definitely needs some tuning here)
Due to the altitude (around 10 meters) I could recover the drone before it did hit the ground, but I couldn’t explain the sudden tumbling at all (around 1:10 in the video), as there was almost no wind…
After this first flight I had a couple more, and I didn’t see this behavior anymore.
So tested altitude hold (much easier to keep the brick in the air), and RTL due to a fence breach worked perfectly, and brought the Quad within a half meter from launch location (10 Satelite GPS lock)
If one of the experts can give me a hint in figuring out why the Quad tumbled I feel a little bid more secure the next flight…
