As luck would have it, after getting a Xuntong's Tu-2VS (it was on a sale after all) and doing some basic research on the subject it appears that this version did not really exist.
Now, it is mentioned in one of the books I perused during the quick research I did as a small footnote, with no specifics.
I know that Xuntong have released the more ubiquitous Tu-2S version. So what would be required to backdate/update the Tu-2VS to Tu-2S.
Does the Xuntong provide all the details in the box to perform this update?
(Or is this just a case of a manufacturer providing and naming what should've been an early and late configurations of the basic Tu-2)
Thanks,
