RE: Quiting this hobby?
Don't give it up.... i'm going into my 3rd year of Mechanical Engineering and am still flying all summer. I don't have to worry about it during the winter as I can't fly anyways so I just practice when I can on the sim. Sure I would love to get into GS gassers but just isn't economical right now, in a few years I will be done and then I can hopefully afford to step up to bigger and better. Right now I will live with the smaller stuff.
Good Luck In whatever you choose!!!
