The latest revision in my ongoing thrust vectoring mount for 24mm model rocket engines. The reason for the 1.5 inch tube is so that I can upgrade from test model rocket engines to 1.5 inch diameter hybrid motors in this mount. Extra hardward required: Servo x2 (SG-90), 1/4" threaded rod, servo rods x2 ,servo rod connectors x2, m6 bolts x4, 8-32 bolt. The entire assembly should be fastened to a fixed plate, that will then interface between the full test stand and load cell mount (check my page for files). I can make different size adapters for the internal engine tube other than 24mm so if anyone would like one please message me! As the part files say, I have iterated on specific pieces of this assembly dozens of times, but more work can still be done, so expect future iterations as well. Message me for other questions!
