The designation for a specific motor looks like C6-3.In this example, the letter (C) represents the total impulse range of the motor, the number (6) before the dash represents the average thrust in newtons, and the number (3) after the dash represents the delay in seconds from propelling charge burnout to the firing of the ejection charge (a gas generator composition, usually black powder ...
Estes produced a wide variety of rocket model kits, normally using paperboard tubing for the fuselage and balsa wood for fins and nose cones. Early models tended to be relatively simple in design, differing in size, number of stages and recovery method. The first kit Estes offered was the Astron Scout (Rocket Kit K-1) which sold for $ .70.
Model rocketry is a safe and widespread hobby. Individuals such as G. Harry Stine and Vernon Estes helped to ensure this by developing and publishing the NAR Model Rocket Safety Codes [1] [13] [14] and by commercially producing safe, professionally designed and manufactured model rocket motors.

An appalling accident rate [5] led individuals such as G. Harry Stine and Vernon Estes to make model rocketry a safe and widespread hobby by developing and publishing the National Association of Rocketry Model Rocket Safety Code, and by commercially producing safe, professionally designed and manufactured model rocket motors. Model rocketry by ...
The Astrocam 110 (or Astrocam) is a model rocket with a built-in camera for taking aerial photographs. An Astrocam ready to launch. The Astrocam was introduced in the 1979 Catalog by its manufacturer Estes and it can be flown with B6-4 and C6-7 model rocket motors (see Model rocket motor classification). The Astrocam was available as kit, or as ...
Jetex 100 - the first Jetex motor Aeromodeller June 1948 Jetex Tailored Skyray kit. The Jetex motor is a miniature solid-fuel rocket motor produced for use as a powerplant for flying model aircraft. Its production led to a number of imitators and, after its discontinuation, successors of similar type.
Figures from tests of Estes rocket motors are used in the following examples of rocket motor performance. [6] For miniature black powder rocket motors (13 mm diameter), the maximum thrust is between 5 and 12 N, the total impulse is between 0.5 and 2.2 N·s, and the burn time is between 0.25 and 1 second. For Estes ‘regular size’ rocket ...
