We use the EPP Boomerang , by Frank Cavazos Model Crafts . We have found that Boomerang is the best all around wing that will fly great in a wide variety of wind conditions.
Conditions range from light to heavy wind.
Best slope conditions are about 10-15mphs. You will need a slope to fly this plane. It will bungee launch and thermal but the most fun will be had on the slope. The EPP Boomerang features an all EPP wing with a carbon rod as a spar. All wings are built with the Hitec Focus III radio and a Sanyo 700mah receiver battery pack.
