- Be careful at launch. Make sure any spectators are at a far distance, and you as well. The flight controllers wires usually go long enough for you to stand far away.
- If the rocket doesn't launch, wait 60 seconds before inspecting the rocket. Make sure the ignitor is all the way in, which is the usual error.
- If you are underage (-10) have some sort of parental supervision, especially at launch.
Step 1: Materials
As the image from NASA shows, each model rocket should contain the following
1. Nose Cone
2. Shock Chord
3. Launch Lug
5. Recovery Wadding
6. Engine mount for (We used one for D and E engines)
7. Rocket Engine (We used a D12-5 Engine)
9. Body Tube (We used a BT-80)
11. Flight Controller (With 4 AA Batteries)
You can get these materials from wherever they provide them. We purchased ours through Walmart, Hobby Lobby, and Estes.
2. Scissors or Utility Knife
3. Pencil for markings
Step 2: The Engine Mount
1. Make two pencil markings on the engine tube (1/2 and 2 1/2 inches)
2. Make a slit with your knife on these two markings.
3. Glue around the part of the tube
4. Lay the engine hook so the side shown on the image is off the engine tube. These will go in a slit and will have glue.
5. Insert the Mylar and green centering rings, in the positions where the two slits made were.
Step 3: Fins
1. Draw the sizes of your fins in proportion to your rocket.
2. Carefully cut them out.
3. (If from a fin sheet) sand the fins.
Step 4: Decoration
Step 5: Installing the Launch Lug
1. Make a glue line near the 4" Mark of the top of the body tube
2. Press the launch lug on it, and make sure it dries before letting go.
Step 6: Shock Chord
1. Place one end of the shock chord near the number 1 part of the paper, make sure it's glued.
2. Fold them. This will make it so you can glue it to the body tube
Step 7: Install Fins
2. Glue fins based on these lines in the guide for each fin
3. Have them dry, set it on a flat surface
Step 8: Install Recovery Systems
1. You will see a little area at the bottom of the nose cone, cut the middle of it out to allow insertion.
2. Pull the parachute lines through it, and tie them.
3. Attach the shock chord, as well. Do so with a knot.
Step 9: Loading the Rocket
1. Insert the engine mount at the bottom of the body tube (side with the fins). This should go in fairly easily. Make sure to put the engine itself in (like my D12-5)
2. Insert 3 folded pieces of recovery wadding. This is important. It's what separates the engine and the parachute, so the parachute isn't harmed.
3. Put in the parachute and shock chord (note the parachute should be folded, they usually come in easy to fold).
4. Close it with the nose cone
Step 10: Launching and Ignition
1. Place the clip ends on the end of the ignitor not going in the engine mount (part not bent)
2. Take the other side, and put in inside the whole in the engine. Make sure it reaches the propellant. Most launch failures are because the inability to put the ignitor in the right place.
3. Pull the engine cap into the engine to stabilize the igniters place
4. Use the safety key before ignition. This is found in the flight controller
5. Count from ten, and push the controllers button and launch.
