i dont think anyone will be using it much, after they get lit up by pintle guns.
Seeing as how the Storch wont be performing any direct attacks vs gv's, the AA pintle guns are going to have to track the aircraft and they are not going to have much "time on target". The Storch will be the eyes and ears, and not much else. The biggest threat to the Storch is going to be Wirbles and that is only if the Wirby gets lucky and has the Storch fly in a line away or towards. I know if I'm in a Storch, and I see a Wirby 1.5k out (lets assume the Storh will be able to see gv's at 1.5k), I'll be staying well away.
If you were in a Wirby, and the only thing to shoot at was the Stork, then sure. But if there is a Hurri IID, IL-2, A20, Mossi, and a Storch airborne in the area... the Stork will be the last thing you'll be firing at. The Stork is not a direct threat.
Think of the Storch as being that little mouthy kid that is hard to catch and has a big brother waiting to blind side you with a hay maker.
