Hello Klaus,
Yes, it is a turboprop, the modified/upgraded version of original Cessna 206 by Soloy. AFAIU from
their website, they discontinued Mark I (the one developed and released for FS by Thomas) and are focused on Mark II production only, which Thomas is also
preparing for us, FS junkies, thanks to his generosity and talents...
I don't know about others, but I've been flying this model in RTMM as soon as it was released. I've long looked for a birdie that would fit my 'RTMM needs' and I've found'em in Tom's masterpiece: i) small, compact but practical for the area; ii) has amphibian and tundra versions; iii) amazingly agile compared, for instance, to its non-turboprop counterparts of sorts... which makes it possible to take it to longer distances.
Thanks for asking!!!
