On an Estes launch rod, with an Estes electric trigger.
Out Side On A Huge Field.
Model rockets launch by sliding up a rod/wire that is pointing toward the sky. A launch lug is a small tube (like a drinking straw on a small rocket) glued to the side of the rocket body. You slide the small tube (launch lug) down on the rod. The launch lug and rod guide the rocket to start it in the correct direction until it gets going fast enough that the fins can stabilize it. Visit the links below. The first picture shows a rocket on the rod. It's a little hard to see but the rod goes through the launch lug. At the very beginning of the second link, they are sliding a large rocket lugs onto the rod.
Yes, it does. I never use more then about a 10 degree offset
It Can Cause The Rocket To Spin Out, and/or wobble of course
Yes, you can use other launch rods. They are all basically the same.
The reason is very clear in the laws codes and regulations that keep safty for other things in the sky and in your launch zone both in the sky and on the ground. If you cant see where it is going then you cannot say that it is safe and will not cause damage to those around you. Flying Conditions. I will launch my model rocket only when the wind is less than 20 miles per hour. I will not launch my model rocket so it flies into clouds, near aircraft in flight, or in a manner that is hazardous to people or property. I will launch my high power rocket only when the wind is no more than 20 miles per hour and under conditions where the rocket will not fly into clouds or when a flight might be hazardous to people, property, or flying aircraft. Prior to launch, I will verify that no aircraft appear to have flight paths over the launch site.
some you need a license but most you don't you can get them at most Hobie shops
You launch it and see, -that's part of the fun of rocketry.
Model Rocket Safety Code from the National Association of Rocketry (at Related Link) # Materials. I will use only lightweight, non-metal parts for the nose, body, and fins of my rocket. # Motors. I will use only certified, commercially-made model rocket motors, and will not tamper with these motors or use them for any purposes except those recommended by the manufacturer. # Ignition System. I will launch my rockets with an electrical launch system and electrical motor igniters. My launch system will have a safety interlock in series with the launch switch, and will use a launch switch that returns to the "off" position when released. # Misfires. If my rocket does not launch when I press the button of my electrical launch system, I will remove the launcher's safety interlock or disconnect its battery, and will wait 60 seconds after the last launch attempt before allowing anyone to approach the rocket. # Launch Safety. I will use a countdown before launch, and will ensure that everyone is paying attention and is a safe distance of at least 15 feet away when I launch rockets with D motors or smaller, and 30 feet when I launch larger rockets. If I am uncertain about the safety or stability of an untested rocket, I will check the stability before flight and will fly it only after warning spectators and clearing them away to a safe distance. # Launcher. I will launch my rocket from a launch rod, tower, or rail that is pointed to within 30 degrees of the vertical to ensure that the rocket flies nearly straight up, and I will use a blast deflector to prevent the motor's exhaust from hitting the ground. To prevent accidental eye injury, I will place launchers so that the end of the launch rod is above eye level or will cap the end of the rod when it is not in use. # Size. My model rocket will not weigh more than 1,500 grams (53 ounces) at liftoff and will not contain more than 125 grams (4.4 ounces) of propellant or 320 N-sec (71.9 pound-seconds) of total impulse. # Flight Safety. I will not launch my rocket at targets, into clouds, or near airplanes, and will not put any flammable or explosive payload in my rocket. # Launch Site. I will launch my rocket outdoors, in an open area at least as large as shown in the accompanying table, and in safe weather conditions with wind speeds no greater than 20 miles per hour. I will ensure that there is no dry grass close to the launch pad, and that the launch site does not present risk of grass fires. # Recovery System. I will use a recovery system such as a streamer or parachute in my rocket so that it returns safely and undamaged and can be flown again, and I will use only flame-resistant or fireproof recovery system wadding in my rocket. # Recovery Safety. I will not attempt to recover my rocket from power lines, tall trees, or other dangerous places.
It guarantees that no matter how many engines your rocket has, or what direction you launch it, it'll always end up on the ground.
