How does the SainSmart Jr. rocket works？
The propeller at the bottom of the rocket works by displacing the air and pulling it behind itself (the action), this movement of air then results in the rocket being pushed forward from the resulting pressure difference (the opposite reaction). The more air that is pulled behind the propeller the more thrust or forward propulsion is generated.
Application of Propellers
Most of the early aircraft used propellers, which were generally slow and flew at low altitudes. Now aircraft generally use turbojet and fan jet engines. However, propeller aircraft are still widely used as transport aircraft, and military anti-submarine aircraft because of their low fuel consumption and good economy.
How to play?
1. Turn the On/Off switch to On and the red status LED will light up, the rocket is now ready for flight.
2. Place the Spinner Missile on the launch pad. Press the launch button and the rocket will power up after approximately 3 seconds. With one press, the flight will last about 4 seconds before the parachute opens. For the rocket to reach its highest altitude (8 second flight time), press the launch button twice in quick succession.
Please Note: There is a 3 seconds delay from the time that the launch button is pressed and the Spinner Missile begins its launch. This allows time to walk a safe distance away from the missile.
