FSX/P3D. I have been preaching Ants Airplanes addons for years now. This developer does a stellar job with each aircraft they develop and keeps them updated over the years. The LSA just got a patch that fixes a number of minor issues and the Eaglet has received major updatews that now includes things like engine wear, VC rain effects, and Flight1 GTN integration. Just when I thought this airplane couldn't possibly get any better, it does! All updates are free, grab them from the shops you purchased them from and if you haven't bought the Eaglet, do it, NOW! You'll love it! Thanks to AG for the tipoff!
