Move up to extreme high altitude flying with the multi-stage CC Express! This extremely fast, high performance, two-stage rocket has two engines, each used during different portions of its flight. Each stage (engine and support unit) is dropped when it ignites the engine in the stage above it. This gives the rocket super high flights! Rocket may be flown in either single, or two stage configuration.
Use the 20mm engine mount assembly to fly this kit with 18mm motors, as required.
