Landing on a sloped ground

[katzmix]

I was out flying Sunday and took off on 45 degree surface. Upon landing it seemed to tilt and came right at me. Im not sure if i had a brainfart or the uneven surface had something to do w it. Hit my truck and broke a propeller

I hand catch it in grass, sand and un-level ground. I would guess the gyros would have sensed the tip, and would have tried to level it self out.
