1946 – BOOSTED BERTHA

Advanced Skill

Estes is proud to welcome the newest member of the Bertha rocket
family. A sport rocket at its core, this multistage flying model
rocket can reach altitudes of 1000 feet! A colorful 18 inch
parachute provides a soft landing, so the Boosted Bertha can be
quickly prepared for another launch.

DESCRIPTION

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!
