Playing with the Hypertek fill stem today, fitting it up to the pad. This is a standard J & L drop fill stem assembly.
The bracket is heavy duty, and quite well made of black anodized aluminum. It’s adjustable and it should handle up to 6” rockets (by turning around the plates). The end of the motor sit on the stainless steel rod with the stem inserted up into the motor, then the collar is tightened up about 25mm above the bracket (according to destructions, looking at the pic,????they are a bit vague here) Then cable ties are tried from the slots in the bottom of the motor to the bolts protruding from either side of the collar. When the motor fires up, it burns through the cable ties allowing the stem to drop down releasing the N2O. (I think)
Motor taped to pad… You can see how much adjustment is available. Those plates can be turned around and swapped around..
Had to lift the rail a bit to clear the linkage below..
Unfinished ¼ Patriot for no reason at all, (just playing around) also note savage Chuwawa….Chewwahwah…Chihuahua…Rat-dog for scale…
