Ready to use Starters (formally known as 2301 Igniters) for your model rockets. Requires one per launch to ignite your engine. Six to a pack for your convenience.
Dependable, easy-to-use Estes Starters. Works just like our 2301 Igniters.
Estes model rocketry is recommended for ages 10 and up with adult supervision for those under 12. Unless otherwise specified, all models require assembly. Tools, construction and finishing supplies sold separately. In order to launch, a launch system, model rocket engines, starters and recovery wadding are required – sold separately-unless otherwise specified.
These spiral wound, Kraft paper body tubes are 14.2 in. in length and can be used as impressive single stage rocket, or it can be coupled with a second BT-80 Body Tube using our BT-80 Tube Couplers to create a super-sized rocket capable of handling any of our 24 mm or 29 mm engines. To accomplish this, simply combine the BT-80 Body Tubes with our Laser Cut Ring Set and it will be possible to create a TARC competition rocket that uses a single Estes 29 mm E16 or F15, a single Estes 24 mm C11, D12 and E12 engine or a 24 mm C11, D12 or E12 cluster rocket for added lift (additional Estes 24 and 29 mm motor mounting components required). To complete the massive size and power capabilities of the BT-80 Body Tubes, a TARC team can incorporate either NC-80K Blow Molded Nose Cone or NC-80B Blow Molded Nose Cone for an impressive and competitive egg lofting rocket.

This accessory pack contains all the component parts for mounting one or two 24 mm D and E engines in BT-55, 60 and 80 body tubes. Included are:
30052 –Large Diameter Laser Cut Centering Ring (qty. 1) This BT-80 body tube centering ring set is laser cut from heavy duty cardstock and allows the model rocket builder the option to insert a single 4 in., BT-50 motor tube into a much larger diameter body tube.
30132 –Small Diameter Laser Cut Centering Ring (qty. 1) This BT-60 body tube centering ring set is laser cut from heavy duty cardstock and allows the model rocket designer and option to insert a 4 in., BT-50 engine mounting tube in a BT-60 diameter main rocket body tube.
30166-2 –AR-5055 Green Adapter Ring (qty. 4) Two spiral wound green rings are glued at marked locations on the 4 in., 24 mm engine mount tube and allow for proper centering of a single 24 mm, C11, D12 or E12 Estes model rocket engine in a BT-55 size body tube.
30164-2 –AR-2050 Green Engine Block (qty. 3) This spiral wound green paper motor tube engine block is glued into one end of the 4 in., 24 mm engine mount tube. However please note on the detailed instructions included with this accessory pack, the distance from the end of the 4 in. engine motor tube that the engine block is glued is dependent on if the designer is going to use a 24 mm C11 or D12 engine or if 24 mm E12 engine are planned for. In either case, installation of the engine block creates a positive stop when glued in front of the engine hook, which keeps the engine from pushing up through the main rocket body at ignition and during the thrust phase of launch.
30368 –BT-50 Engine Mounting Tube (qty. 3) These BT-50 Engine Mounting Tubes are the key component to providing the necessary thrust to lift a single egg to 800 ft. in a TARC competitive model rocket. Each tube is cut to 4 in. in length and when assembled with an engine block, engine hook, engine hook retainer and the appropriate centering ring size, TARC teams can explore the potential lifting limits of their rocket design.
30480 – Black EngineHook Retainer (qty. 2) This special, spiral wound black paper tube is glued to the outside of the BT-50 engine mounting tube to securely hold the pre-bent, metal E engine hook in place.
35005 –Spacer E to D (qty. 1) This orange colored spiral wound paper spacer is used when converting from a more powerful 24 mm, 3 ¾ in. length E12 series engine to a less powerful and shorter 24 mm, 2 3/4 in. length C11 or D12 engine.
35021-D Engine Hook (qty. 1) This engine hook is bent from a mild, but durable steel and is used with an engine hook retainer to hold 24 mm C11 and D12 size engines in a BT-50 spiral wound motor tube for the ignition and ejection phases of launch. The hook is not recommended nor will it work with our 24 mm, 3 3/4 in. long E12 size engines.
35022-E Engine Hook (qty. 1) Pre-bent from a mild, but durable steel, this engine hook and is used with an engine hook retainer to hold 24 mm E12 size engines in a BT-50 spiral wound motor tube at ignition and during the thrust phase of launch. This hook will also work with our 24 mm C11 and D12 engines by placing an orange colored D to E spacer in the engine mounting tube before inserting a shorter length Estes C11 or D12 engine.
