Here is another large rocket I designed/built using depron structure. I chose the Jupiter C that launched our first satellite. I'm using a 29mm stuffer tube with a 14" long by 3" diameter parachute bay as the spine. Only ply used is a thrust plate at the bottom, and one at the upper section to attach the recover device to. A couple of internal ones to center the 3" tube.

I found a funnel at a craft store and trimmed it to adapte the satellite to the second stage tub.

The transition at the top is a little oversized due to the 3" tube going down into it.

I built up the second stage can using depron stringers and sheet. The satellite is made from bt-20 tubing which is slightly oversized.

Target weight is 53 oz rtf with a G motor, right now it might be an ounce or two over due to the density of the 2mm sheeting I got being higher than the online spec.

The altimeter has an access hatch held closed with magnets.

Right now sheeting is done, I just need to build the fins, and add some details.

Diameter is 7" and height is 82.5" long. It should handle most 29mm H motors as well as any g motor....Continue Reading
