4.1. Sélection du moteur
Estes model rocket engines are assigned a letter indicating their power level. For beginner rockets like the 3 Bandits, engines starting with the letter 'A' (e.g., 1/2A3-4T, A3-4T, A10-3T) are generally the best choice. Always refer to your rocket's specific instructions for recommended engine types to ensure optimal performance and safety.
4.2. Recovery Wadding
Recovery wadding is crucial for protecting the recovery parachute from the hot ejection charge of the engine. Insert several sheets of wadding into the body tube above the engine before packing the parachute. Use new wadding for each flight.
