I agree with all the above. I strive to build better airplanes than the next guy or to better my last project. For me the ultimate rush is building an airplane and have it trim out and fly perfect. Most of the time the people that ask "why do you build" never have and dont understand the satisfaction. Besides flying is only about 1/3 the hobby. 1/3 building 1/3 people 1/3 flying. If your only doing 2/3's of it your ripping yourself off. LOL
