your key to the Space Age! Whether you are just getting into the hobby or have been in it all your life, Semroc offers something for everyone.

Thousands of model rocket enthusiasts have flown kits and engines from Semroc since 1968. We look forward to flying with you.

We have just released our first ten Ready-to-Build™ kits in time for NARAM-52. These have been in the works for some time and incorporate many ideas and suggestions that have come to us over a fifty year span. I know you are thinking that all model rockets are ready to build. We have been asked many times if we offer ready-to-fly or almost-ready-to-fly kits and we have to respond that we are not large enough to do those, BUT all of ours are ready-to-BUILD. This new series is really ready to build. They all have through-the-wall laser cut balsa fins to fit precision laser-slotted body tubes cut on our new automatic laser cutter. They all have a "new" insulating inner sleeve to protect the external body tube, elastic cord, and parachute from the hot flames and gases from modern delay and ejection charges. The elastic cord on all the models is increased to 36" for better protection from nose cone "smiley's".

The line starts with the new Start™ based on an early design by Bill Simon. Another of Bill's designs formed the inspiration for the Sky Hook II™. From Semroc's early days, the Aphelion™ and XK-23™ are upgraded to RTB technology. Three of Centuri's Large Scale designs have been downsized for ABC engine simplicity and economy. They are the Mini Hustler™, Mini Aero-Dart™, and Mini Explorer™. One of Gene Street's most popular designs has been downsized to the Cherokee-C™. Two of Mike Dorffler's designs have also been downsized for the line. The huge Optima has inspired the Mini Optima™ and the Omega carrier rocket has been downsized to the Mini Omega™ with a scale (non-functional!) version of the Cineroc.

Just in time for the summer flying season, Semroc has released three new kits. The Centuri Orion™ is based on the Larry Brown design from 1971. Although sharing many details from the Saturn 1B and Saturn V, it was in turn based on an even more futuristic design that his father had built years before. A great demo ship that is perfect for all modelers. The level of detail can range from little to master craftsman.

The Excalibur™ is a Retro-Repro™ version of an early Centuri kit from 1972. It is over two feet tall and performs well on a wide range of engines. Fiber fins make it an easy to finish kit. If you like two-stage action, we have also released the #8 Booster kit that Centuri added to convert the Excalibur™ to an Excalibur 2™. If you order an Excalibur before July 1, 2010, we will include the #8 Booster free with your order!

One of the earliest customizable kits was the Centuri Vector-V™. We have recaptured some of that fun with our Retro-Repro™ Vector-V™. See how many unique ways you and your friends can build this bird.

The Mark by Semroc™ is a recreation of the earliest version of the Mark from EI in 1961. The original Mark was designed for EI by G. Harry Stine while he was President of the NAR. It was Catalog #K-2. Our kit features a BT-30 body tube, balsa nose cone and balsa engine block. It includes a rubber shock cord and paper streamer like the original.

The Semroc V-2 is based on the K-22 semi-scale model of the German V-2. It includes both the scale and semi-scale laser-cut fins. This has been one of the most requested kits at Semroc.

The Space Plane™ is back at Semroc! The Space Plane was designed by John Shutz and Vern Estes and was released as Catalog #K-3 in 1961.

The X-Ray™ xKit™is based on an early clear payload model released in 1964 as Catalog #K-18.

The Penetrator™ xKit™ is a recreation of the first Flight Systems, Inc. (FSI) kit. It features pre-cut plywood fins, round elastic, and an engine mount to work with modern 18mm engines. It can be fired with 21mm engines, if you have them.

The Constellation™ xKit™ is a recreation of another clear payload design. It featured distinctive teardrop fin tips and was released in 1968, originally as a free kit.

The SST Shuttle-1™ xKit™ is a re-release of an original Centuri Engineering design from 1971. It was their Catalog #KC-17 and was based on some early NASA shuttle designs.

The Nighthawk™ xKit™is based on the Classic pop-pod glider designed by Gene Street, based on his first patent of the pop-pod concept. Easy to build and trim, the Nighthawk is a smooth performer.<

Many more xKits™ are in the works!
