"The Recon Aircraft have an OPTIONAL mission ability to make a tactical reconnaissance run." - from the write up.
I really want to avoid any confusion here. The recon missions are optional. That is to say if the CiC assigns them, they can, or, they can opt to just use them as just bombers. There are only 6 Arados per frame, they are really included for some history...and variety, they will certainly not be a "main type" in the FSO.
Same with the Spit 14s. They, as an option, be used as recon fighters, in the same fashion, or just be flown as a regular fighter. Its up to the CiC to assign them the tasks.
Both types can also, looking at the above, roll as a recon a/c, land, reup, and fly a fighter or bomber sortie. So there is room for some creativity here.
Regards.
