Once I wanted to record onboard video of my rocket flight. I had Sony Xperia Go smartphone which I didn't use anymore because it was outdated. It's video recording was still quite OK, so I decided to use it as video camera.
I was a beginner and for several reasons the flight failed. But I still got some video:

They don't sell them anymore and I burned mine up trying to make a former that is larger than an 8 inch'er. I contemplated what to do about this and I came up with a...

Posted by Redrocketman in Redrocketman's Blog, 20 June 2016 -

When casting a cored r candy motor, is there a basic formula to determine core diameter. I believe core should be 1/3rd of the I/D of the grain / motor? Correct?
So if I was to cast my regular weekend blazer ( simple 400mm X 45mm nozzle-less ) I can figure out core diameter no problem, but is the a maximum allowable limit to how far into the motor,...

I've been working off of a supply of real black powder and using the one ounce per pound formula for decent altitude. I'm going to run out of the real stuff soon, and am testing my black powder quality and production process to see what adjustments need to be made to get my shells into the air.
