Ultimate Pneumatic Launch System Upgrade Kit (Launch Panel and Air cylinder retrofit to existing pad)
This is needed if your compressor is: 1: located at a distance, or 2: You don't have a gauge or a reliable gauge on your bicycle pump or small compressor. Gauge placed in airline near end of line for easy reading.
Gauge, Regulator, and Mini-inline Valve Assembly
This option is recommended if you have a large compressor. The regulator adjusts the pressure at the launch pad (in the rocket) to that which is desired. The mini-inline valve allows the person launching the rocket to rapidly pressurize the rocket (5 seconds or less) to the desired pressure. The mini-inline valve when used in conjuction with the regulator acts as a safety feature....it keeps the students from over-pressurizing their rockets. A special brass fitting is placed at the end of the launch pad airline that accommodates most compressor hose threads (1/4 inch NPT).
