4. Setup (Pre-Launch Checklist)
Before each launch, ensure your rocket and launch equipment are properly prepared:
- Engine Selection: Choose an appropriate Estes engine from the recommended list: 1/2A6-2, A8-3, A8-5, B4-4, B6-4, B6-6, C6-5, C6-7. The first letter indicates power level (A being the lowest, suitable for beginners). The numbers indicate delay and thrust.
- Recovery Wadding: Insert fresh recovery wadding into the body tube before each flight. This protects the parachute from the hot ejection charge.
- Igniter Installation: Carefully install the igniter into the engine nozzle and secure it with the igniter plug, ensuring good contact.
- Launch Pad Setup: Set up your launch pad in a large, open area, away from buildings, trees, and power lines. Ensure the launch rod is vertical and securely anchored.
- Launch Controller: Connect the launch controller to the igniter clips. Ensure the safety key is removed until ready to launch.

5. Operating (Launch Procedure)
Once your rocket is prepared and the launch pad is set up in a safe location, follow these steps for a successful launch:
- Place Rocket on Launch Rod: Slide the rocket onto the launch rod, ensuring the launch lug glides freely.
- Connect Igniter Clips: Attach the igniter clips from the launch controller to the igniter wires, ensuring they do not touch each other or the metal engine casing.
- Clear the Launch Area: Ensure all spectators are at least 15 feet away from the launch pad. Announce your countdown clearly.
- Insert Safety Key: Insert the safety key into the launch controller.
- Initiate Countdown: Begin your countdown (e.g., "5, 4, 3, 2, 1, LAUNCH!").
- Press Launch Button: At "LAUNCH!", press and hold the launch button until the rocket ignites and lifts off.
- Observe Flight: Watch your rocket ascend. It will reach its peak altitude and then deploy its parachute for recovery.
6. Recovery and Maintenance
After a successful launch, the Alpha III will deploy its parachute for a gentle descent. Follow these guidelines:
- Retrieve Your Rocket: Locate and retrieve your rocket. Be mindful of where it lands and avoid hazardous areas.
- Inspect for Damage: Check the rocket for any damage to the fins, body tube, nose cone, or recovery system. Repair any damage before the next flight.
- Replace Wadding: Always replace the recovery wadding with fresh wadding before each subsequent flight to protect the parachute.
- Store Properly: Store your rocket in a cool, dry place, away from direct sunlight and extreme temperatures.

7. Troubleshooting
If you encounter issues, consider the following:
- Rocket Fails to Launch: Check the igniter connection to the engine and the launch controller clips. Ensure the launch controller batteries are fresh (4 AA alkaline batteries required). Verify the safety key is fully inserted and the launch button is pressed firmly.
- Parachute Fails to Deploy: Ensure sufficient recovery wadding was used and properly inserted to protect the parachute. Check the shock cord and parachute for tangles or damage.
- Unstable Flight: Verify that the fins are securely attached and properly aligned. Ensure the nose cone is firmly seated.
