In the light industrial districts that have sprung up around FSX, X-Plane, and DCS World, genuine craftsmen aren’t all that hard to find. The machine tools that whirr and thump and whine in the workshops of add-on makers like A2A Simulations and PMDG are operated by passionate perfectionists – driven micrometer wielders whose scrap bins brim with components that look, on first, second and third inspection, absolutely flawless. Elsewhere in Simulatia, it’s a different story. Just about the only sim that can boast a third-party add-on as lovingly fashioned as this Texan or this Fishbed, is Train Simulator. I enthused about that add-on – a delightful Class 205 DEMU – a few weeks ago, and in today’s Flare Path I talk to the outfit behind it, Armstrong Powerhouse.
