r.m.r
Rec.models.rockets (r.m.r) is a Usenet newsgroup developed for discussions and topics related to model and high-power
rocketry. The purpose of this newsgroup is for the exchange of information between anyone wanting to build, fly, or use model rockets or high power rockets. These are viable alternatives to amateur rocketry.
The term "model rocket" is defined based on non-metalic structural aspects, weight, propellant and total impulse restrictions, electrical ignition, recovery devices, and factory-made, solid propellant engines.
The term "High power rocket" aludes to any rocket using model rocket technology (as described above) except lacking the weight, propellant, and total impulse restrictions of model rocketry. Amateur rocketry, pyrotechnics, rocket motor-making, and "EX" rocketry are related topics that fall outside of the scope of this newsgroup.
DESCON
The name Descon comes from combining the two words: DESign and CONstruction.This website is an attempt to compile information on model rockets that is easy for all readers in r.m.r to understand.
Model rockets
A model rocket is a small rocket that is generally advertised as being able to be launched by anybody, to commonly low altitudes (most commonly to around 100--500 m (300--1500 ft) for a 30 g (1 oz.) model) and recovered by so many different means.
According to the United States National Association of Rocketry (NAR) Safety Code, model rockets are constructed of paper, wood, plastic and other lightweight materials.
The code also provides guidelines for motor use, launch site selection, launch techniques, launcher placement, recovery system design and deployment and much more.
Ever since the early 1960s, a copy of the Model Rocket Safety Code has been provided with most model rocket kits and motors. Despite its inherent association with quite flammable substances and objects with a pointed tip transit at high speeds, model rocketry historically has proven to be a very safe hobby and has been credited as the most important source of inspiration for children who eventually become scientists and engineers.
