Wayne McCullough has added the Short 184 WW1 biplane bomber to Landships II here:

There are meant to be 3 versions including plain white, but clicking on the links gives the same tan version. Maybe it'll be fixed later.
Kancho Iliev's added a new T-2 Buckeye trainer at

Selected FG biplanes in smaller sizes (not WSAM) in JPEG files. Looks legitimate as it's also being updated by FG.
I found this before Chip passed away, when it was set up and maintained by his son.
There are 4 versions of a new Junkers J.1 in 1/72 scale at the Landships2 website, under Models/Wayne McCullough. Check out the other contributors as well, there's a 1/144 L.13 Zeppelin if you haven't seen that one before.
