Model Rockets FAQ



Frequently Asked Questions about Model Rockets.

This FAQ about Model Rockets was compiled and written by Wolfram von Kiparski with numerous contributions by others.

Rec.models.rockets (r.m.r) is a Usenet newsgroup created 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 components, weight, propellant and total impulse restrictions, electrical ignition, recovery devices, and factory-made, solid propellant engines. The term "High power rocket" refers to any rocket using model rocket technology (as described above) except without 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.
