Estes Star Hopper Kit (12pcs)

An amazing set of parts for the construction of twelve Star Hopper rockets, must not be missing in the collection of any rocket. Enjoy a lot of fun with these almost 19 cm high rockets. A return device in the form of a streamer is included with each rocket so that all rockets hit the ground safely.

Difficulty of building a rocket

Models of construction difficulty missiles 1 require a bit of dyeing, or gluing and grinding. The models have parts made of laser-cut wood or plastic moldings, a plastic or balsa cone and high-quality decals. Assembling the model is easy thanks to step-by-step pictorial instructions. You will spend about one afternoon building this rocket model.

For information on building and launching, see How to Operate Missile Models.

Phases of flight

1. Ignition of the engine - the propellant ignites the propellant mixture in the engine . The required direction of flight is ensured by the guide rod of the launch pad, on which the rocket is slid.
2. Thrust and acceleration - the rocket is powered by the reactive power of the rocket engine.
3. Combustion of the propellant mixture - as soon as the propellant mixture burns, the delay mixture begins to burn, which produces a large amount of smoke . This is used to monitor the flight of the rocket. The fast-moving rocket is now starting to slow down.
4. Peak flight and ejection - after the delay mixture burns out, the ejection mixture is ignited, which activates the rocket return system.
5. Return system - is most often implemented using a parachute, ribbon, or so-called heli-blade.
6. The last phase is to hit the rocket on the ground.

Rocket engines

Engine igniters and seals are included in the engine package, unless otherwise stated. Estes engines are equipped with electric igniters, designed to be ignited via the launcher. The rocket can be fitted with Klima engines with conventional fuses or electric igniters. More information on rocket engines can be found in the rocket engine overview.

Sweep seal

The cotton swab seal is made of non-flammable fabric, its purpose is to prevent damage (burnout) of the parachute from the engine sweeper.

Assembly tools

To assemble the model, you will need: scissors, pencil, sandpaper, sanding block, model knife, universal glue, plastic glue and acrylic paints for possible painting. For comfortable cutting and protection of the table during assembly, we recommend a work mat.

Flight altitude measurement

You can measure the achieved flight altitude of the rocket using a digital altimeter, which is inserted into the rocket. You can use a sextant to measure height from the ground.
