INTRODUCTION
Thank you for choosing the Wattage Extra 330L EP ARF and welcome to the exciting world of electric-powered
aerobatic R/C airplanes! Whether you have built and flown other electric R/C airplanes in the past, or if this is your first, you
will appreciate the high quality, ease of assembly and excellent flight characteristics of the Extra 330L EP.
The Extra 330L EP is an electric-powered, four channel semi-scale aerobatic airplane utilizing balsa and light-ply
construction materials. The built-up balsa and light-ply wing has been designed with a semi-symmetrical airfoil that stays
very stable throughout the entire flight envelope, yet makes inverted flight and aerobatics smooth and easy. The fuselage
is built up using balsa and light-ply and the tail surfaces are built up using lightweight balsa. This adds up to an airplane
that is light, very aerobatic and exciting to fly.
When you open the box, you will notice that you won't have much left to do or to purchase to finish your new
airplane. Included is a prewired 480 size motor and a dual-ball bearing gear box already preinstalled under the molded
cowling. The Extra 330L EP comes with a complete hardware package that includes wire pushrods, control horns,
wheels, molded wheel pants, propeller and other miscellaneous hardware. The airframe is completely built-up and cov-
ered by master craftsmen using real iron-on covering material. They take their time to ensure that every part is straight
and properly glued.
