As far as helios go in FSX I can remember wayyy back when the late Rory Kelly began to experiment with issues of rotorflight, kind like days Mike Stones experimental funny hell flying machines. This Sikorksy is worth time its set up perfect for pretty true simulation heli flight. There are a few more add ons make chopper flights type out there now. Nemeth and Virtavia do good at those simulators Area 51 another. Having an issue crashes Windows 10 ithas two main DLL fikes that were added from acceleration. When windows came it made changes different version dlls xuipc dll UI AutomationCore dll, may be multiple listings, one you want original. all this about data ram memory, has fact flight making on tool bar keeps saving retrieve doesnt have to, thats why considered powerhog, because going longhand these beginning formative components program adaptable most eloborate precise simulator ever created date. Its 32 running usually 64 witha 86 drive. Another confounding other MS simulatuion programs but yet graphics loss actions visible elements due fs9 compatibility issues. AI isnt finished by far, soon found new way transition application over perfection Giabyte then my friends fun begins, true, MSFS very nice, technical, glitzy BUT itll awhile before perfect, believe our hair colors will changed, if we remeber how much lost last 14 FSX, was it.
