75mm Hybrid Reload Information:

All Hybrid Reloads include:

(5) Press-Lock Injectors:  The Easiest, Fastest way to connect fill lines to motor during preparation.

(2) 6 Foot Fill Lines:  2 Line Fill System is needed (a simple T-Fitting will do great).  The Motor Fills through these lines. 

(1) Low Pressure Vent Line:  Used to Vent Nitrous Oxide Vent Gasses Away from Loaded Motor and to a point where they can be seen at the time of filling.  
(1) Fuel Grain:  Fuel Grains are the fundamental part of a Hybrid Rocket Motor.  This is your fuel which you will burn during the motor fire.  
(2) 24 Volt Igniters
