Rear Eject Bomb Rocket (18mm motors)
thingiverse
I had 24mm and 13mm designs of rear eject bomb rockets, but not an 18mm design. So here it is. Assembly is similar to the 24mm versions so see my things on that for an idea on assembly. For this rocket you will need: 200mm of BT-60 body tube for the outer tube 170mm of BT-55 body tube for the inner tube 170mm of BT-20 body tube for the motor tube 15mm of BT-80 body tube for the fin ring Streamer 12" parachute Some kevlar cord for a shock cord. These are a little tricky to pack, so keep that in mind should you build one. But they're pretty neat to see fly. Video of flight: https://www.youtube.com/watch?v=uvsBjzlzl1A
