Is it better to buy parts? I just simply bought a whole plane for my first purchase
Also, don't make airports far apart. Planes have different range and if you don't have airports in between to make stops, you'll be screwed
Yeah, the airports I own (Nagasaki, Osaka, Sendai, Sapporo and Vladivostok) are all at close range so I can go from any given airport to another with any airplane.
As for better buying parts.. I'd say so. The problem is it's hard to actually get all those 3 needed parts together to build the plane itself (engine, controls and body). I have two controls for Navigator-P and Wallaby-P, but can't find the other parts at all
