hobbyshophand,
in my mind there is no such thing as a quality RTF. there are quality ARF's.
The purpose of RTFs is not to Xzude your idea of quality, but introduce beginners to flying. Some model enthusiasts enjoy building ARFs, modifying and tinkering as much as flying; others don't have the time or interest in ARF building projects; and others are addicted with every aspect of the hobby.
The GWS Slow Stick ARF at $35 offers no more quality than the Slo-V airframe with its mainwing. The name of the game for many is having FUN ASAP with an inexpensive total package RTF flyer more than spending the time and money on detail workmanship and a Spectrum or Futuba TX. Combat SPADs aren't the most beautiful quality product, but they serve a purpose for many that provides hours of flying enjoyment for a lot less money than flying a $350 aerobatic plane that Xzudes quality. A beginner only needs so much 'quality' to enjoy this hobby.
Every newbie will eventually find their area of interest and there are a lot of choices to attract your money before you discover your calling/limitations. One way is to begin with the advantages offered by RTFs. For someone to say that the RTF HobbyZone SuperCub is not a 'quality' product for the money is out of touch with reality. Some flyers have more fun with an inexpensive RTF than other flyers have with their 'quality ARF,' but to them experiencing the satisfaction of building an ARF that Xzudes quality is more to their interest/fun in the hobby than repairing/rebuilding a SPAD every week for the next TopGun battle.
One could argue that some lazer cut ARF airframes Xzude less quality/durability than some HobbyZone and ParkZone airframes or other RTF foamies depending on their use/abuse. Why should a
beginner with limited resources spend the extra money on a 'quality' ARF Mountain Models lazer cut kit and the other expensive items to maintain that level of quality when they don't offer any significant advantage in learning enjoyment than a beginner can experience learning to fly with a RTF HobbyZone SuperCub or RTF ParkZone Slo-V.
