    Easy To Recover

    This Baby Bertha takes off amazingly fast for a hefty rocket on mini-motors. Recovery is easy once the chute deploys. if you enjoyed this rocket, you will definitely enjoy this rockets counter-part, Big Bertha.

    This rocket always comes back to you no matter what. Hard to see in flight due to size, but once the parachute opens, it can be seen from anywhere.

    New take on a Classic

    This was a father/ son project for Cub Scouts. It is a really neat redo of Big Bertha. It launches well and looks super cool when it parachutes back to Earth. I need to build Big Bertha in order to complete the set!

    Big Berthas’ little kid!

    This kit has so many possibilities. You can paint it up in a classic bertha paint scheme, or combine it with other parts to create the classic “Goonybirds” that Estes had in the ’70s
    Very stable, and will fly for years….

  9. Amazing rocket

    cool looking and A+ launching and flight

    This rocket is very easy to assemble. It flies almost perfectly and the parachute prevents it from a fast descent. It is amazing to see how slow they can parachute back down. I painted mine a dark blue color and it looks awesome.

  10. Rocketeer Todd

    A+ for Baby Bertha

    This stocky little rocket is easy to assemble, stable in flight, and a real kid-pleaser. Add it to your fleet if you don’t already have one.
