Right, an update from my side.
Frior-one talked me trough the duck-hunt setup (C-47) and how to replay to see my own errors.
I also tweaked my stick settings, to decrease stalls. Both were a major step forward.
Yesterday, I mentioned a steady aim was very hard for me, then someone mentioned Trim.
I wish I knew that before... I was already training up my arm muscles...
Result: got my first human-on-human kill yesterday.
delta7: looking forward to those tracks!
Many thanks all!
