This flight started as a new personal altitude record atempt but ended a little under 500m up, due to right motor fail.

At the time where it happend I thougt that the aircraft just had stalled, but it took too long to recover so i decided abort the record attempt and get the plane lower. And all the way home I did not feel anything other than the strong wind.

Or at least I thougt everything was ok, until I tried to go around that bush again.
