I have never designed a plane for Real Flight so please forgive my ignorance if this isn't possible: is there a way to convert these 7.5 designs to work with G5? My ancient computer can't run better than G5. If there is no converter, is there a way to extract the design variables to make the RF included "slinger" wing fly as close to a FT mini arrow as possible? Thank you.
Unfortunately there is no way to convert the planes from 7.5 to G5. Backwards compatibility is a tough nut to crack, hence only the 7.5 models. As far as the aircraft specific variables go the G5 physics engine would not do a good job of translating the information into a usable flying craft. You would really need to fly a real Arrow and then play with the Slinger in G5 to make if feel similar.
