5.0 Rocket Construction
5.1 Model rockets are commercially available or they may be built from readily available materials. The following requirements apply when building model rockets.
5.1.1 Materials - model rockets must be made of lightweight materials such as paper, wood, rubber, and plastic suitable for the power used and the performance of the motor. Metal must not be used for the nose cone, body or fins.
5.1.2 Motors - only commercially available and certified model rocket motors of Hazard Division 1.3 or 1.4 can be used in the manner recommended by the manufacturer. The model rocket motor, its parts, or its ingredients must not be altered in any way.
5.1.3 Recovery system - always use a system that will return the model rocket safely to the ground. Only use flame resistant, biodegradable wadding if wadding is required.
5.1.4 Power limits - model rockets must be propelled by one motor. The maximum motor size allowed is 325.0 g.
5.1.5 Stability - determine the stability of the model rocket by established engineering principles.
5.1.6 Payloads - never carry live animals or a payload that is intended to be combustible, explosive or harmful.
6.0 Launch Procedures
6.1 The following requirements apply when launching model rockets.
6.1.1 Launch site - launch model rockets outdoors in cleared areas, free of tall trees, power lines, buildings, dry brush and grass. Clearance distances must meet the requirements of Table 3.
Table 3 - Clearance Distances for Model Rockets
6.1.2 Launcher - launch model rockets from stable launch devices that provide rigid guidance until the model rocket has reached a speed adequate to ensure a safe flight path. To prevent accidental eye injury, always place the launcher so the end of the rod is above eye level or cap the end of the rod when approaching it. The launcher should have a jet deflector device to prevent the motor exhaust from hitting the ground directly. Always clear the area around the launch device of brown grass, dry weeds, or other easy-to-burn materials.
6.1.3 Ignition systems - the system to launch medium and large model rockets must be remotely controlled and electrically operated. It should contain a launching switch that will return to 'OFF' when released and have a removable interlock. Only use electric igniters recommended by the manufacturer that will ignite model rocket motors within one second of actuation.
6.1.4 Launch safety - ensure that people in the launch area are aware of the pending model rocket launch before the audible five-second countdown commences. If the model rocket suffers a misfire, do not allow anyone to approach it until certain that the safety interlock has been removed or the battery has been disconnected from the ignition system. Wait one minute after a misfire before allowing anyone to approach the rocket.
6.1.5 Flying conditions - launch model rockets only when the wind is no more than 30 kilometres per hour. Do not launch model rockets so it flies into clouds, near aircraft in flight, or in a manner that is hazardous to people or property.
6.1.6 Launch angle - the launch device must be pointed within 30 degrees of the vertical. Never use model rocket motors to propel any device horizontally.
6.1.7 Recovery hazards - if a model rocket becomes entangled in a power line or other dangerous place, do not attempt to retrieve it.
