X-15:­ Streaking to a speed of 4,500 mph and an altitude of 350,000 Space feet, the rocket propelled X-15 carried astronauts like Neil tothe Armstrong to the edge of space. Shuttle Cox's authentically detailed scale model (13" in length) ed9e gives you a vivid and exciting re-creation of those early America flights. Its solid-propellant engine thrusts it off the of launch pad toward space. Then, as it passes maxi­ mum altitude, it deploys a re-entry parachute to land space safely, ready for another thrilling flight. Cox's X-15 is molded of high impact plastic, has accurate NASA markings. Comes complete and ready to launch for less than $6.00. Fly it today.

Lift off! And up, up to the very frontier of space streaks Space Shuttle America, the hypersonic transport, carrying shuttlecraft loaded with men and mate­ rials. At NASA ground control, the -signal is given and the shuttlecraft leave the mother ship to fly their cargo on to an orbiting space station. Un­ loaded, they return to earth to rejoin the mother ship for another trip. Cox's exotic Space Shuttle America cap­ tures in realistic miniature the excitement of this excursion into space. It blasts off, climbs to altitude, then separates. The mother ship parachutes safely to earth. The two shuttle­ craft glide gracefully in a circular "re-entry" flight to a perfect landing. · Space Shuttle America includes: Beautifully styled transport. Two detailed delta wing re-entry gliders (designed for catapult launching if desired). Engine retainer ring and flameproof ejection wadding. And extra detailing decals. A fascinating glimpse into the future of space explora- tion. Approximately $8.00 . At hobby, toy and department stores.

Well, NARAM-14 is over, and the Seattle peop le showed us that they know how to run a meet. The motel fa cilities were exce llent , and the A COMPlETE Holida y fnn staff was most cooperative . Frankly, with 122 participants MODll from 25 states (Alabama, Arizona , California , Colorado , Conn ecticut , Florid a, Georgia, Illinois, Iow a, Kansas, Maryland , Massachu se tt s, AND Minnesota , Montana, Nevada , New Jersey, Ne w York, Ohio, Oregon , HOBBY Penns y lvania, Rhode Isla nd, Te xas, Virg inia , Washington, and Wisco n­ sin), the meet was somewhat larger and more represe ntativ e of the NAR CENTER than ex pected. Because the ran ge was organized well and there weren't DEDICATED too many contestant s, the laun ch ing ran smoothly. We o nly wish that our Model Racketeer duties would ha ve let us see more of Seattle. TO THE The Model Rack eteer congratulate s Jess Medina, Jim Worthen, Hazel NEEDS Gerhart, Dick Berg , and the rest of the So uth Seattle Rocket Society for running an excellent meet. 01 We'd like to thank all the many peopl e who helped with th e H088YISTS Rack eteer's NARAM covera ge: Jay Apt , for writing, photographing, and staying up all night developing picutr es; Jan Blickenstaff , for writ­ ing, typing, proofreading, taking picture s, and otherwise being helpful ; Mark Bonin, for developin g film, printing picture s, letting ou r photo­ graphers use his darkroom, and for staying up all night with them; Phil Engelauf, for pro ofreadin g and shower ing the staff with Riverside, Californi a bottle cap s; Dave Klau ser, for writing, proofreading, and developing film ; Ron Wright, for help ing .Phil ; all the reporters who covered events and discussion gro up s; and the NARAM-14 staff for supplying a typ ewriter and being helpful in too many way s to list.

The launch site , a 40 acre field, was located ju st north of the Boein g Space Center in Kent , Washingt on, a suburb of Seattle . The center of rang e operations was a she lter of constr uction scaffolding roofed with black plastic. This pro vided the shade for safe ty check-in , return and launch contro l. Th e launch system used was a modified misfire-alle y consisting of two wings or satellites controlled from one cen t ral loca tion . Each wing had its own launch panel and 12 individual pads which were spaced far enough apart for immed ia te launch ing of models without enda ngering contestants loading their rockets on adjacen t pads. Each pad was mounted on a camera tripod adjusted to about 18 inches and had both 1/8 " and 3/16" rails plus an adjustab le tower, thus el iminating any conf usion ove r special rail assignments. The re was a separate check-in for each wing but only one return ta ble. Data reduction calc ulat ions were done at the Ho liday Inn as the dat a was recei ved from the field. T he other center of ope rat ions on the field was the concession stand manned by the Civil Air Patrol . Pancakes, ham and eggs, hot dogs and hamburg ers were among the m enu attractions. ~he CAP also provided the four tent s used for the prep area and manufa ct urer s' (AVI, Centur i, Cox and Estes) disp lay ran ge st or es. A parachute awn mg served as shade for the picnic tab les and " Model Rocke teer Field Headqua rt ers". Tr acking _ for Eggloft'. Design Efficiency, and various altitude record attempts was done with two bubble leve l tube sight tripod scopes on a 300 met er base line . A hard line headset system was used for communicat ion with the laun ch area.

The overwhelming majority of rocketeers flew some sort of BT-5, ½A6·2 comb inat ion . Since towe r launchers were an integral part of th e SS RS laun ching syste m, most co mpeti to rs chose to ut ilize this dra g sa ving device. The winn ing models were beautifully polished.

''Allrocket m ,otor are ·NOTalike!'' Leroy Piester

When it comes to small model rocket motors like A, B, and C's, yqu could be safe in saying that they are all ABOUT the same. But, when you start talking about E's and F's ... you better take another look! There's a BIG difference in these! Enerjet motors look a­ bout the same size as convent ional E's and F's, .. but that 's where the sim iliarity comes to a screeching halt!! Our casing is different .. . our nozzle is different . . . and BEST of all, the propellant is different! Completely different!!

Words can't possibly describe the remark­ able perform ance* that Enerjet motors give, so rather th an showing you thrust/tim e curves and all the rest ... we suggest that you try 0 Enerjet and really find out for yourself. We know you ' ll be convinced . that "All rocket motors are NOT alike !"

*If you were at NARAM -14, you know what we mean. Incidently . . . at NARAM -14 an Enerjet Nik e Ram using a factory production Enerjet motor exceeded the World Open Payload record by 1000 f eet! R ecords are also pending in .the Condor Boost Glide (Pterodacty l} and rocket Egg Loft (Egg Crate}. . ·
