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).

Zahrnuli jsme praktický výběr nástrojů, vodítek a lepidel pro vaše stavby UKROC.
Lepidlo na dřevo je docela slušné, ale epoxid je pevnější. Kyanoakrylát (super lepidlo) je také místy užitečný a je skvělé ho nakapat na konce trubice, aby je absorboval a zpevnil, aby se prodloužila životnost vaší rakety. (I když s tím budete chtít být opatrní!)
