For me it's a passion, anythign that flies. But I do have other hobbies. Mostly R/C related. But I also build paper models, and Lego.
That's the definision of a hobby. somehting that you can keep yourself entertained with for as long as you want.
Becoming a better pilot is all what's it's all about. While you have the trainer, and are thinking of another build, try to hone your flying skills. Trainers will do most aerobatic manouvers, practice them. You can fly in the winter.... You will also start to look forward to windy days, as trainers make good 'stringless kites'. Vertical landings, and jsut floating the plane in front of you is a blast!
The flyinig feild is also a social gathering. Most men I know fly for that reason alone!! to get away from the wife for a few hours!!


-poking fun everyone.. we all go home to our wives!!
