For many of us the hobby is both flying and building. It sounds like for you the hobby is flying. Excellent. Nobody is saying your time isn't worth anything. Some of us are saying that you can't put a dollar value on your spare time when it comes to comparing build versus ARF/RTF. Each of us decides what priorities we put our spare time into. That's why these constant debates are silly. My priorities are different from everyone else. There is no reason for anyone to convince anyone else as to which approach is "right" because each person must make their own determination of what is right for them and them alone.
