O5500X-PS 98MM DMS HIGH POWER SINGLE USE MOTOR
I haven't launched the O5500X yet but will be doing so later this year. Instructions include a link to an online video that seems very thorough. You'll want to view the video a couple of times before installing the grains. My only issue so far is that Aerotech instructions specifically call for using Elmer's Glue-All Max, but they shipped the ape brand instead. I've always used Elmer's Glue-All Max for grain-to-liner bonding and prefer it over other brands. Unfortunately, it's difficult to find locally, and a shipment from a popular online retailer arrived with the glue unuseable (it was too thick to squeeze from the bottle). I wish Aerotech had sent the glue they recommend in their instructions.
