Estes is proud to welcome the newest member of the Bertha family, the Boosted Bertha. This beaut rounds out the collection by being the first in the series to feature a two-stage rocket booster.
A sport rocket at its core, the second booster of this multistage flying model rocket will push this Bertha skyward, reaching twice the height of Big Bertha. The Boosted Bertha will reach altitudes of 1000 feet when powered with an Estes C6-0 engine in the booster stage and an Estes C6-5 engine in the main rocket. After the first stage ignites, the booster jettisons and gently tumbles back to earth. Once the rocket reaches apogee, the rocket will deploy the recovery system—a colorful 18 inch parachute. This provides the Boosted Bertha a light landing so that it can be quickly prepared for another launch.
Quality Estes body tubes, laser cut wood fins, a molded plastic nose cone, and easy-to-apply waterslide decals make for a full day of building enjoyment. Once painted to perfection, this Bertha is a must-have for any rocket collector!
