i upgraded from the FC3 A-10A to the DCS A-10C
but not because it was clickable. i upgraded because it was more modern and had more capabilities. i would never bought a DCS A-10A, because it would have been basically the same aircraft but the A-10C was different enough. if there are new FC3 aircrafts i would rather have different aircrafts and not FC3 versions of a DCS module
so i vote for none
but interestingly you forgot to add the option. strange
