as a sim beginner the parameters on G-3 are a pain to understand . been hitting the knifeedge.com forums and there is allot of help trying to figure it out never used the AFPD sim but it sounds a bit easer to change values,I have to add knife edge is starting to have more downloads for planes there are still allot more for AFPD for sure ,still any sim is going to help with your "skills" I have added on to my sim and am super happy with it after the kids are in bed rip a few touch and goes and some tricks the more stick time the better, before the sim landings were well lets just say a good chance of success, maybe LOL, after sim solid and reliable mistakes are corrected faster just better flying in general allot more pieces in my bag of tricks.
