The likely hood of a second plane crash is very high. Your second plane will more than likely meet it's demise with mother earth. This is because it is capable of doing things your trainer is not, and eventually you'll push it over the edge. I think it pretty much happens to anyone. For this reason, I'd go with a good point and fly plane that isn't that costly, and isn't as time consuming building as a scale plane would be. Get something like a four star, or tiger series. These are great plane, and will teach you a lot about how to fly those scale planes that you eventually want. And, when you crash it, it won't matter as much as if it were an 80 inch scale piper cub! Then, for your third plane, have fun!
