I'm not sure what you mean about poor quality unless you have unrealistic expectations for "cooler" foam. It dents easily unless you coat it with a finishing epoxy. There are some shortcomings in the box packaging design for shipping and parts of the design may require some upgrades. The FlyFly models are unique foam designs that are fun to add your experience into. If you don't have any EDF experience, I would recommend sticking with the smaller foam models. Even the smaller fiberglass models require some experience and are more difficult to fly than the larger foam models.

The next "step up" for an equal size would be the fiberglass fuselage models with sheeted wings from a company in China (which I forgot the name of). They are distributed in the U.S. from places like [link=http://easytigermodels.com/index.php?main_page=index&cPath=15&zenid=e3b1ed230 a49cda05276d2f617ec1a11]Easy Tiger - Tigerline 101mm[/link]. I'll be starting a build thread on their F-86 soon.

Another one of these models is distributed via Nitro Models as the Predator UCAV. You can see my build thread [link=http://www.rcuniverse.com/forum/m_8294238/tm.htm]here[/link].

There is also another build thread on this forum for the X-29 also at Easy Tiger Models.

Good luck!
