Pre Launch Inspection Cut a ¾” square of wadding and carefully push it well into the body tube. Note: Never use toilet paper or tissue paper; they are flammable. The wadding is a barrier designed to keep from burning up your recovery system and nose cone.

Pre Launch Inspection One person represents the team and sits at the lab table with rocket in front. On teacher’s command, the engines are inserted in the body tube and tightened in by adjusting the engine retainer.

Pre Launch Inspection 4. Then, the teacher assists students installing igniter contacts and yellow plugs. Next, students carefully place their rolled streamer and recovery system into the body tube. Last, students carefully place their completed rockets into a cargo box that the teacher will use to transport rockets to launch pad.

Model Rocketry Safety Code Construction—My model rocket will be made of lightweight materials such as paper, wood, plastic and rubber. Without any metal as structural parts. Engines—I will use only pre-loaded factory made model rocket engines in the meaner recommended by the manufacturer. I will not change in any way nor attempt to reload these engines. Recovery—I will always use a recovery system in my rockets that will return them safely to the ground so that they may be flown again. Weight Limits—My model rocket will weigh no more than 453 grams (16 oz.) at lift off. And the engines will contain no more than 113 grams (4 oz.) of propellant. Stability—I will check the stability of my model rockets before their first flight except when launching models of already proven stability. Launching system—The system I use to launch my model rockets must be remotely controlled and electrically operated and will contain a switch that will return to “off” when released. I will remain at least 20 feet away from any rocket that is being launched. Launch safety—I will not let anyone approach a model rocket on a launcher until I have made sure that either the safety interlock key has been removed or the battery has been disconnected from my launcher. Flying conditions—I will not launch my model rocket in high winds, near buildings, power lines, tall trees, low flying aircraft. Or under any conditions which might be dangerous to people or property. Launch Area—My model rockets will always be launched from a clear area free of any easy to burn materials and I will only use non-flammable recovery wadding in my rockets. Jet Deflector—My launcher will have a jet deflector device to prevent the engine exhaust from hitting the ground directly. Launch Pad—To prevent accidental injury I will always place the launcher so the end of the rod is above eye level or cap the end of the rod with my hand when approaching it. I will never place my head or my body over the launching rod. When my launcher is not in use I will always store it so that the launch rod is set in an upright position. Power Lines—I will never attempt to recover my rocket from a power line or other dangerous place. Launch Targets & Angle—I will not launch rockets so their flight path will carry them against targets on the ground and will never use an explosive warhead nor a payload that is intended to be flammable. My launching device will always be pointed within 30 degrees of vertical. Pre-Launch Test—When conducting research activities with unproven designs or methods, I will when possible determine their reliability through pre-launch tests. I will conduct launchings of unproven designs in complete isolation from persons not participating in the actual launching.
