Once the rocket reaches its peak altitude, it will gently return to earth on its brightly colored, matching orange 12 inch parachute. Whether you're a first time rocketeer or a long time flyer, the Alpha III Launch Set makes launching easier than ever.

LAUNCH SYSTEM includes Estes Porta-Pad II Launch Pad and Electron Beam Launch Controller.

Curious how high your rocket really flew? The Estes AltiTrak™ makes altitude tracking simple, fun, and accurate without the cost of expensive electronics. With just a quick pull of the trigger, you can follow your rocket through its flight path and capture its peak altitude in seconds.

Originally designed for educational use, the AltiTrak is also a favorite tool for hobbyists, clubs, and rocket enthusiasts of all levels. Use a single tracker for quick altitude readings or pair two AltiTraks for even more precise measurements. Lightweight and easy to use, it won’t interfere with your rocket’s performance—just pure, measurable flight data every time.

• Easy to Use: Simply pull the trigger, follow the rocket, and lock in your reading.
• Affordable Accuracy: Track altitudes without costly electronics or added rocket mass.
• Great for Education: Engages students with real-world data collection and analysis.
• Precision Potential: Use two AltiTraks for greater accuracy in measuring altitude.
• Versatile Tool: Perfect for classrooms, hobby launches, and science projects alike.

History of Antar Model Rocket

The "Father of Model Rocketry" and founder of the National Association of Rocketry is Harry Stine (NAR #02). What's more, he is one of the original pioneers that founded the hobby right alongside Vern Estes, Stine was also a talented writer.

Estes' designers created a precise replica for this Designer Signature Series kit. Moreover, it is based on multiple sketches and the original model, which belongs to Bill Stine, Estes Vice President and the son of Harry Stine.

In 1951, people didn't have the hobby of flying model rockets yet. Therefore, they didn't design Antar as a flying model rocket. Stine was a physicist and clearly understood the science of flight. So even though Antar was a fictional vehicle, the science behind it meant it could be stable in flight.

Antar Model Rocket:

• Initially created in 1951
• They did not design it as a flying model rocket
• Designed to be stable enough in flight to be used as a model rocket
• Precise replica created for the Designer Signature Series kit by Estes' designers
• Replica based on multiple sketches and the original model owned by Bill Stine, Estes Vice President and the son of Harry Stine

Overall, the history of the Antar model rocket is a fascinating story. It showcases the innovative and adventurous early hobbyists who laid the groundwork for modern model rocketry.

Build across multiple body tube sizes with this 6-pack of Estes Shock Cord Anchors. Includes two anchors each for BT-50, BT-55, and BT-60 rockets—perfect for versatile builders and rocketry enthusiasts.

Made from durable ABS and backed with strong 3M adhesive, these anchors offer quick, clean installation and a reliable upgrade from paper shock cord mounts.

One of the timeless ready-to-fly rockets from Estes, the Athena model rocket kit is one of the coolest model rockets. It comes fully assembled which means you get to the flying field quick. So grab a friend and get ready to have some fun!

Fully assembled; Athena is a great looking, high flying model rocket with superb performance. Perfect if you have no time to build or just want to add to your collection. 

It comes pre-built and is ready to fly in minutes. We designed the Athena model rocket kit as a great high-performance rocket for newbies.

The Athena reaches heights exceeding 1,100 feet when launched on Estes standard model rocket engines and its brightly colored, 12-inch parachute makes it easy to recover.

Bill Simon collaborated with Estes to design the Belt Object Survey Ship (B.O.S.S) over 40 years ago. This was a time when the introduction of nuclear and solar power revolutionized space flight technology.

This unique rocket, which was not initially intended to be a model rocket, has been eagerly awaited and is being released as a prototype for the first time. With the B.O.S.S. Rocket, you can experience the innovation of the past with the latest addition to Estes' Signature Series.

We matched the Belt Object Survey Ship (B.O.S.S) design with premium components for top quality. Our mission is to bring you the latest in the Estes Designer Series. The B.O.S.S. Rocket comes with a rare asymmetrical structure, featuring:

• One tail fin for increased stability and control during launch.
• Two engine pod assemblies for maximum thrust and performance.
• A large circular plate to provide additional stability and balance during flight.

Experience the beauty of space with Belt Object Survey Ship. This is a vivid testament to the ingenuity and creativity of the early space enthusiasts.

The Estes B4-4 Rocket Engines are ideal for mid-powered model rockets that demand a steady climb and reliable deployment. These single-stage, 18 mm engines offer a balanced performance with moderate thrust, making them a great choice for both new hobbyists and seasoned flyers looking for consistent flight results. The B4-4 is specifically designed for rockets weighing less than 3.5 ounces, including the engine, and provides dependable altitude and ejection timing for small to mid-size models.

These engines feature a thrust duration that supports a smooth boost phase, followed by a 4-second delay that allows rockets to reach peak altitude before recovery system deployment. This delay makes the B4-4 especially suitable for rockets with moderate drag and stable flight characteristics. Whether you're launching in a park, field, or on a certified range, you can count on a satisfying launch profile with every flight.

Each package includes three B4-4 engines along with four starters and four plugs, giving you everything needed for multiple launches. The extra starter adds an extra level of convenience and value—ideal for those who like to be prepared on launch day. Estes' attention to safety and performance ensures that each engine delivers the reliability that model rocket enthusiasts have trusted for decades.

Whether you're conducting a classroom demo, building your personal fleet, or hosting a weekend launch session, the B4-4 engine is a proven performer. Its moderate power and predictable deployment make it a smart option for a wide range of Estes kits and compatible low- to mid-weight rockets. Get ready for consistent results and fun flights with this time-tested engine.
