This is going to be a 2 forum thread. The research motor portion will be over in the Research forum.... and the actual rocket build will be here. More then likely some of the posts will overlap. This first post is identical in each of the threads.
This is not going to be a fast passed build thread!
A year or more ago Gary and Karl gave me a spent O5040X https://d11fdyfhxcs9cr.cloudfront.net/templates/170652/myimages/o5280x_rcs_assembly.pdf that had been static tested out at Black Rock. My intentions are to refurbish the motor and turn it into a subminimum diameter rocket.
I have played around with using spent DMS motors in the past. I built a subminimum dia 54 for Hamster Dance at Balls 2019 The rocket sort of worked great, motor worked ('trade mark' term Mark Clark), the fins stayed on but my shock cord parted at apogee. so the concept worked.
I've done a few long motors (not crazy Mike Fisher long) Bottom is AT 98/15360 (36" propellant), middle DMS 98mm O5040 (51" propellant), Top Dr Rockets 98/25600 (60" propellant)
This is what the 98mm DMS motors look like inside. ( I cut a spent motor case in half length wise and made the grains out of salt for a demo motor for STEM stuff) https://d11fdyfhxcs9cr.cloudfront.net/templates/170652/myimages/m1340w-ps_rcs_assembly.pdf
