On a Facebook post, the company has talked about the development of the R44 and the R66 and why they have somehow postponed the R22 as priorities changed.
As VSKYLABS puts it, “at the present, the VSKYLABS R66, R44 and the Cabri G2 are covering the major target categories for mainstream, popular training and general aviation helicopters simulation. So, with the several existing R22's out there, there is no severe *void* left with this decision. In the light of the above, shifting the R22 down in priorities was a good call in several aspects.”.
VSKYLABS did not disclose a release date but they have confirmed they are actively working on the model.
