I am currently enrolled on Patator'forum (link: www.patator.frbb.net).
I introduced several of my achievement there, and I am on this forum to learn and m'expérimenter still a bit more about your techniques etc ...
So as in the title I have a launcher project. a coaxial starter aluminum or steel, all done by a boilermaker.
Here's a diagram:

I do not know when the project starts but I have to go a bit of money before any ^ ^. I will also recovered a refrigerator compressor to climb higher and faster pressure.
That is a can about everything I wanted to say that I am a minor I'm only 12 years but people of patator'forum considers a minimum of "responsible".
That's good evening!
