Foxtrot Rocket

cults3d

This rocket i made up and built from scratch, I guess if i had any sort of inspiration it would've come from the Saturn1B rocket with its individual tanks but this rocket is quite different. You print the Foxtrot-Rocket-Motors.STL for its base as well as the Mid-Transition. These 2 piecess make up the lower part of the rocket, you can make these any dimension you want, It requires you to run a BT-50 (24mm) Central Core tube up the middle, accomodating a D/E motor. You can print the "24mm-EngineMount-Stop" for your ring to slide in for the Motor Stop unless you have a cardboard to use. An E motor is 95mm long and a D motor is 70mm long, so you will need to put glue on this ring and slide it in the bottom end of the BT-50 Tube. Make sure you allow for a Motor Retainer to protrude at the bottom end of the tuibe and i suggest that you Build this to accomodate an E motor, you can always use a D motor with a spacer on top, this way you have more options depending on wind conditions. I have a 3D printable spacer available as well, located at https://www.thingiverse.com/thing:5115001 Then, you will need 6 of the BT-5 (13mm) tubes of same length for the outside perimeter of the lower rocket section. When i made this rocket, I used 12" lengths of the BT-5 tube and then a single 14" length of the BT-50. At the top, BT-70 tubing can attach on the top of the Mid-Transition do be your upper section of the rocket. I've not gotten into building much for nose cones, but you could use some of these i found: https://www.thingiverse.com/thing:3044665 https://www.thingiverse.com/thing:4317027 (the sustainer nosecone) https://www.thingiverse.com/thing:4326339 Or obviously choose whatever you want. this nosecone i've designed, scales up to BT-70 nicely as well: https://www.thingiverse.com/thing:5136841 last but not least, you can either make your own fins out of balsa or your favorite type of wood, or you can print 6 of the fins i've included. Since the BT-5 tubes all mount inside of the Base and Mid-Transition mounts, there is a wall that protrudes out, my first trials with this had the BT-5 tubes fitting inside the tube but ultiumately i went this route. Anyway the fins have a notch at the bottom of them so that they can mount lower, just like in the image provided. You could also mount the fins to the BT-50 tube in the core which might look kind of cool. The 24mm motor retainer is not my own, but i end up using it for my own rockets quite a bit. Have fun with this, please feel free to reach out if you have any troubles
