Description: Plywood fins and centering ring upgrade for the Estes pro Series II Super Big Bertha Model Rocket kit #9719 Condition is "New". The Estes Super Big Bertha is a cool upscale model of the classic design from Vern Estes. It's a big, 2.6" inch rocket over 3 feet tall, but the balsa fins included in the kit make it pretty fragile. This kit allows you to dramatically stengthen the rocket and fly it on higher-impulse motors. This is a plywood upgrade set of fins for the Estes Super Big Bertha kit. The kit includes 4 fins and 3 centering rings that are one-to-one copies of the balsa and cardstock fins and rings in the Pro Series kit. These fins are drop-in replacements for the kit parts and will significantly improve the durability of your rocket allowing you to use higher-power motors. These parts are precision laser-cut from 1/8" Baltic Birch plywood. This is not a complete rocket kit. Thanks for looking.
