Argus As 10

The Argus As 10 was a German-designed and built, air-cooled 90° cylinder bank-angle inverted V8 "low power" aircraft engine, used mainly in training aircraft such as the Arado Ar 66 and Focke-Wulf Fw 56 Stösser and other small short-range reconnaissance and communications aircraft like the Fieseler Fi 156 Storch during, and shortly after World War II. It was first built in 1928.[1]

gollark: I do also have some personal services running on the same infrastructure, but I barely have to tweak those.
gollark: So it appears that the comments system is down because I recompiled my website with the new domain so the status/images links would be right, and forgot to stick in configuration for proxying to the comments backend onto the new domain. I have to deal with bizarre issues like this *constantly* just to keep my stupid projects in existence and available.
gollark: I can't tell.
gollark: Creature says lots of things like that, maybe ironically.
gollark: ... oh no, the comments system is down again.
