Ground support equipment is essential for rocketry.

You need a launch pad and launch controller to launch your rockets from. You also need wadding (or re-usable options) to protect your parachute each time.

We recommend the durable Klima launch pad and their launch controllers let you install two PP3 9v batteries at once for some extra launching juice! The Klima pad can take a 3mm or 6mm rod as well as a launch rail if required for larger rockets.

The estes pads are also great and the Porta pad E is very good for mid sized rockets also.

Bulk packs for schools and clubs

You can shop for bulk packs of rockets here. We list the packs of rockets on their own with bundles on the page so you can add everything you need in one click.

The bundles include motors, launch pad(s), launch controller(s), batteries and wadding. All you will need to run your club or rocket workshop will be the required tools and consumables for construction. Rocket manuals are on each page so you can check but in general with these starter kits you will likely need the following although not all of these are required by all kits.

Some wood glue (We like gorilla glue but all sorts of PVA should be OK).
Scissors, masking tape, sand paper, decorating supplies (pens etc).

You can checkout on our website and still pay by Invoice (or card / PayPal etc), no setup needed just follow the instructions. And it won't delay your order either!

Centering rings & bulkheads

Centreringsringe og skotter er vigtige dele, når man bygger en raket fra bunden.
Du kan bruge centreringsringe til at placere rør inden i rør. Et eksempel på dette er ved at montere dit motorrør i din hovedramme. Vi sælger stort set alle størrelser centreringsringe, så hvis der mangler noget, så giv os besked!
Bulkhoveder er gode til at lime fast på koblinger for at fastgøre øjebolte. Dette er en god løsning til f.eks. at fastgøre din nyttelastsektion til dit hovedraketrør.

Eksempel: Du vil montere 3x 18 mm motorrør i en BT-70 raketramme. Vælg dobbeltpakken BT70 - 3x 18MM. Denne fås i en "T"-version og en standardversion. T-versionen har rektangulære huller til motorkroge ved rørhullerne.
