Thanks, :) its basically a Jtube utilizing only 3 blocks, gravity fed, most of the block rockets I've seen online are fed from the front and need to be constantly fed. This one is much better in the
feed department, and also has a very short or nonexistent burn chamber, which I've grown to adore over the last 3 years of experimenting with rockets. I believe the riser makes a great burn chamber, and the horizontal burn chamber
should always be super short, since you really want the flames and turbulence in the riser as much as possible
