Launched it with a video recorder in the nose cone today.
Not a very impressive video, but you can get a kick out of the cattle mooing at the end.  M72 LAW ( Light Anti-Tank Weapon) Model Rocket On Board Video |

Not for nothing but for some reason I was browsing a lot on the rocketry forum and there have been a fair amount of catastrophic explosions with the refillable motors. There is the same risk with the cardboard and plaster motors but when they explode they don't have the metal shell for Containment. Solid rocket motors that are dropped can sometimes end up with a crack or cracks in the propellant. That crack exposes much more of the propellent and increases the burn rate. That causes excessive pressure that will rupture the case and in essence it becomes a giant firecracker. I've had C and D motors explode on the pad, and I would not want one exploding in a launch tube beside my head, et alone an E motor. ---- Another issue would be finding a rocket that burned quick enough to finish before it left the tube on a model LAW. |

Does anyone know of a firearm spring .etc that is like the AR15 hammer spring but thinner and as strong? I need them to deploy the fins and the AR hammer spring is likely too powerful and bulky. The AR trigger spring would be more ideal but it doesn't have enough range. It doesn't have to pop the fins all the way open, or hold them open, it just has to lift them off the body so that the pressure of the air passing over them will pull them back the rest of the way. |

My new extruder and hotend will be configured very similar to this one.

With the rocket motor, I'd definitely want protection
The Panzerschrek had a blast shield 
Originally the operator wore a gas mask without the filter when firing to protect the face.

I've been using a new filament for the 3d printer (PETG) and it is so much better and super strong. I'm getting lots of retro ideas in my head lol.

Probably will only share my files on an individual basis. Do you have a 3D printer? |
