If your going to fly off a high start and on flat ground buy something else. Flying wings make horrible thermal ships. If you are a very good pilot you "might" be able to keep a EPP wing up on a good day. When looking for a Thermal plane think BIG! The larger planes are easier to launch, land and thermal. EPP wings are designed for slope use not thermal flying. There are lots of ARF themal planes. Unfortunatley none are the same price as a Zagi (but you get more than 2 pieces of foam and a few misc bits too).
