The Estes 1345 Mosquito Model Rocket kit follows the time honored formula for high performance - put the biggest engine you can into the smallest package. It worked for muscle cars and makes it possible for this 3.8" tall rocket to fly up to 800 feet with the largest allowable engine (A10-3T). Continuing with its minimalist theme recovery is handled by tumbling back to earth. This is a Skill Level level 1 kit so some assembly and painting is required. The fins are laser cut balsa wood, the nose cone is plastic and water slide decals are included. Completed kit measures 3.8" tall x .54" diameter. Weight (without engine) is 0.11 oz.
