I have told many of my friends this, When I don't think I can fly anymore I will keep right on building, and I will get a good pilot to fly for me.. If you love the planes and building.. there is never a reason to quit...
Some of my friends are of the opinion that If they can't crash it ...nobody will, I can't understand that personally ?
In fact i don't really like flying at events, but if my buddy that I trust wanted to fly them, I would be happy to co-pilot
big crowds = big nerves to me ! hahahahah
If you are having fun, and being safe....you are doing it right
