Here's the deal, back when people actually built their planes and that was the norm, you would go over every submicro detail that went into it, fine tuning it, not skimping in any area and not rushed to complete it. If you did opt to cut a corner, in the back of your mind you are thinking, do I really want to risk it all over one little detail I overlooked, or skimped upon considering how much time I put into this plane? You don't just pre-flight, you pre-pre and pre-flight it entirely on your own because you don't want something to go wrong and lose your plane.

With modern ARF's and RTF's, they are assembled at the factory at the absolute lowest end costs possible in order to be marketable. These are not the same planes at all, neither the owner can take full pride or control over how they are assembled, well, not without heavily revising one, entirely because that part has been taken out of their hands. I've had some really weird stuff happen with ARFs no pre-flight could have predicted, and it was just how they are put together. When I crash an ARF, I think, well, there is something I gotta do differently with it, either to handle the crash better, or to prevent it due to failure of some sort.

I like to scratch build new designs, so play test pilot alot, and with some of these planes I fly, you are literally rolling the dice to see if it's going to fly at all, and if so, how is it going to perform or react. I always test these out in secluded areas so I don't have to worry about harming others, but even with these creations, I know what hardware I put into them as well as the overall structure itself, but given, with the ones that crash, or have hard landings, the pre-flight get's taken well past the usual and everything is triple checked and stress tested before taking it up again.

I feel for you old man, these kids just don't want to go to extreems detail wise and it's putting strain on you to keep them up in the air, not to mention the pressure, and having them be kind of off to boot really makes it even harder. Maby if you crashed a few, they'd think twice about not doing the pre-flight better, then again. I do think having them rolling down the runway right after landing is a bit much for anybody though, you may have to just tell these guys that you want to B.S. in the back with the rest of the members as well, or at least take a short break between flights, that pace would drive me nuts and take all of the fun out of your day.
