Advanced Skill

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!

WHAT YOU NEED TO BUILD: Scissors, pencil, ruler, sandpaper, carpenters glue, plastic cement, hobby knife, masking tape, clear tape, primer (white), paint (orange, white), clear coat (optional). Tools, construction and finishing supplies not included.

  1. Rocket Guru

    Thank you Estes, for this next addition, by the looks of Boosted Bertha and my past flights with the Bertha family, Mini to Super. Once purchased, I will be modifying mine, starting with the trailing edge of the 2nd stage fins, to match the leading edge, of the 1st stage booster fins, then staggering the fins will not be necessary, as shown, improving the aerodynamics and altitude. It should also be a great up powered rocket to 24mm, but only C11-0, or D12-0 motors, for the 18mm and some 24mm motors are the same length, on the 1st stage and D, or E motors in the 2nd stage. Just swap out the motor mounts, use epoxy, cut through the tubes fin slots, redraw the fins with extensions, use 3/16inch launch lugs and add nose weight for a stable C/G. At around 2,000feet you might use a GPS tracker, to retrieve Bertha, if boosted… hint, hint bright flashy colors.
