(ROL Newswire) -- Roadrunner Rocketry Inc. introduces three 29mm single
use composite model rocket motors in the F and G impulse class. These
motors include a two-wire igniter, have a built-in thrust ring and have
7-10% more impulse than competing motors, all at a suggested price about
20% less than competitive offerings.
Roadrunner propellant produces white/grey smoke with a bright white
flame and a moderate burn time. Rapid propellant is a short burn, high
thrust propellant producing a moderate amount of dark smoke that makes
it easy to track flights. The motors are as follows:
A G80 (Roadrunner Rapid) with total impulse of 108 n-s, peak impulse of
114 n, and a burn time of 1.4 seconds. Delays are 4, 7 and 10 seconds,
with retail pricing of $20.95.
An F60 (Roadrunner Rapid) with total impulse of 77 n-s, peak impulse of
90 n, and a burn time of 1.3 seconds. Delays are 4, 7 and 10 seconds,
with retail pricing of $18.95.
An F35 (Roadrunner) with total impulse of 78 n-s, peak impulse of 50 n,
and a burn time of 2.3 seconds. Delays are 6 and 10 seconds, with retail
pricing of $18.95
These single use motors are fully assembled and contain 62.5 grams or
less of propellant. Utilizing a one piece molded casing, the motors have
been extensively tested and have proven to be highly reliable and easily
ignited. Certified by the National Association of Rocketry, the motors
are also approved by the California State Fire Marshal for sale and use
in the state of California.
Roadrunner has substantial inventories of each motor ready to ship and
is in the process of establishing retail distribution and launch site
motor vendors. Interested parties should contact Roadrunner by email.
