Guys, I think that "expert" isn't such a terrible thing to accomplish.  I've been flying my Aerobird for six weeks, and can keep my Yak in a hover for 5 minutes at a time.  The fact that it's on Realflight's hover trainer and I'm only controlling the roll axis and still manage to crash doesn't detract from my accomplishments.  I'm SURELY an expert.  I'll give you all tips!

Haha, on a more serious note...I do think that people like Andrew Jesky, Bill Hempel, Alan Szabo Jr, and Quique Somenzini (to name a few) should be classified as experts.  They won't admit it, or at least I hope they wouldn't.  I do think that you don't have to be an expert to give advice...nor do you have to fly much.  I'm one of the aforementioned gum-bumpers that doesn't fly much.  The reason I don't fly much is because I've had a string of small and stupid issues that have kept my planes grounded....and I've finally gotten fed-up with tweaking and fixing them.  That fixing/tweaking comes this week, and hopefully they'll all be ready to fly by next weekend.

Another thing, I think that people can be experts without having to be able to do everything.  A guy that focuses on scale flight and has a 1/3 scale Fokker Triplane completely scaled out and flying like the real one is an expert scale artisan/pilot.  What if QQ couldn't do it?  Does that make him any less of an expert?  I don't think so!  I still think he's an expert at what he does.
