A model rocket kit includes reusable parts, and requires launching equipment and single-use launching supplies. These kits are recommended for children 10 years and older, with adult supervision advised to age 12. Rocket kit assembly encompasses a range of skill levelsfrom Easy-to-Assemble (E2X), requiring only simple gluing and less than an hour of timeto Level 5, requiring multi-step assembly with measuring, cutting, gluing, and painting tasks. Reusable rocket kit components include a cone, a body tube, and a recovery parachute. A rocket engine, a starter, and recovery wadding are used once. Rocket engines come in a variety of sizes, time delays, and burn durations. A "first-flight" engine recommendation is generally made for each rocket kit. A launch pad has a stable base and a vertical rod that provide vertical stability during initial liftoff. A launch controller has a keyed ignition switch to prevent accidental ignition, and a cable provides a safe distance from the rocket during launch. Bulk packs of model rocket kits are available for clubs and schools, and allow groups of children to experience building and launching a rocket.
Estes manufactures model rocket kits, launching equipment, and rocket engines. The company, founded in 1958, is headquartered in Penrose, CO.
2. Estes 2274 Recovery Wadding
Feature
Rocket AccessoryContains 75 Sheets
Enough for 18-25 flights
Flame resistant
Required for most rockets
Description
Estes Recovery Wadding keeps your parachute in perfect shape when used properly. The leading cause of unsuccessful flights is failure of recovery deployment. If your rocket is precious, consider one of Model Rocket Shop's Recovery Upgrade Kits with Kevlar, Nomex and a nylon parachute. Replacing Estes fragile knicker elastic shock cord and "bin-liner" parachute and using permanently attached Nomex cloth instead of paper wadding can lengthen the service life of your missile!3.
