In reference to FSX (the second pics is evidently taken from that sim, as you can understand from the water reflections), in the Premaircraft main page they state that:
NOTAM: WE ARE PART OF THE FSX BETA TEAM AND RECOMMEND THE DELUXE VERSION
Apart from the recommendation (how many FSX version will b availble?) I guess an FSX version of the Turbo Beaver is presently ready, and I have an idea all the future projects in this or other planes' series by Premaircraft will be released with this in mind.
An interesting thing is the simplification of the installation procedure: for every Premaircraft model, so far, you had to install separate packages for sound and panel, and then download a file including model and textures for each livery available (many, indeed). The whole process was mind-crippling, even because files had to be spread all over half a dozen different folders, and this explains why the web-pages are so full of instructions on the matter.
This time, instead, you have all in a single file, and everything has to be dropped into the FS9 main folder.
Anyway, I'm glad you like it: the Beaver is a favourite of mine since always, and the fact FSX has it as a stock plane is a joy to me - and now this amphibian... need another cigarette
