I don't have any opinion either way. I also have been in the hobby for around 40 years. I love to build but on occasion I need something quick to fly so an arf fills the bill. I recently had a very hard landing with my TF giant P51 and totally knocked out the landing gear and a little damage on the wings. Now, referring back to my building experience, I was able to duplicate the landing gear mounting blocks and ribs and make it as good as new. I also was able to repair the small dents in the wing. I don't know what I guy that only flies ARFs would do in this position except maybe pay someone like me to fix it. It seems to be a question about not only time but does this flyer want to invest in the tools needed to build or repair a model. Us builders already have the tools so it's a no brainier. I love the building aspect of the hobby, it makes it complete for me.
