Yeah, either that or the Extreme Flight 74" would be my next plane of choice just purely basis my personal flying experience. The EF was the closest thing to the big boys that I have flown to date. It handles incredibly well for an 11 pound plane. Its just a good next step in the progression that can be made at a reasonable cost. You can build one for about $1200-$1500 give or take and a 50CC is going to cost about $2000-2500 to do up right. If you have the money you could go from your Inspire or Showtime right to a 50CC with no problem, its just a little more expensive and unless you buy one with a 87" plus wing, I dont think they will fly any better than the QQ or the EF.

One thing, seriously. If you are really serious and have the monely, spend the money now on a good sim like AFPD or G3 and a decent graphics card to run it.. You will not regret it and you will advance 100 times faster than without.
