RE: Satisfaction From Rebuilding
I also enjoy a rebuild and get pleasure from the effort, but... it depends upon the plane. I've done heroic rebuilds on favorite planes but a recent crash of a Spacewalker saw the fuselage undamaged and the wings repairable with moderate effort and I've no desire to rebuild it. It was a nice looking plane, but did not fly to suit me and I no longer want it taking up limited hanger space or engine and radio gear.
I'd have to think that some planes that hit the trash can fall in that category... they are just not given enough value to warrant a rebuild effort. Someone else might give it value... and it is good to see such a plane find a new owner.
