I played on G3.5 for many months before evening getting a plane to build.. I trained with an instructor at my club and after a couple of flights he felt I knew how to fly.. A real plane is a little nerve racking at first but remember to breath.. the one big thing that at sim cannot mimic the prep... Tuning in an engine can be frustrating, getting your plane trimmed is a little trial and error and not getting caught in the fun flying is hard to do.... I was having so much fun my first day with my plane that I lost track of time and ran out of fuel but the pulling off a loop or a roll first time up is a great feeling
