I have been using @ScorpionFilm422 's GNS530 & GNS430 from day 1, and now his GTN750.
Of the very few CTD issues associated with these MODS, most have been caused not specifically by the Mod, but by the MS kernel that all MSFS simobjects uses.
Whats sets these Mods above most others, is the quick & professional support supplied by the developer . If there is a issue, it is fixed almost in Hours, not weeks.
