Up something sleeve got skytrain........??
I do as it happens. Not counting my chickens yet, but I'm pretty happy with the UTVA-65. The 3-view matches that in Observers perfectly, save for the cockpit. The only description I've found of the -67 (bear in mind it wasn't actually built) says its got a larger hopper and a "redesigned fuselage", which would imply that the 3-view would not match.
We'll wait for WK, but in the meantime I'm back in the garden. Will check-in later.
