Update 13 September 2018 @ 1835z:
Some new images of the Bonanza were shown off on the A2A forum; you can find them below.
Over on their Facebook page, A2A Simulations announced that their upcoming Accu-Sim V-Tail Bonanza is “on short final…”. Included with this little teaser was a single preview of the V-Tail coming into land.
That’s all that was shared for now, though it was hinted at by A2A that they’ve implemented a form of rain visualization into the Bonanza; time will tell whether that turns out to be factual or simply a tease for what’s to come. We’ll let you know when the aircraft is out.
