The Flying Porta Pad Launcher
When I first saw the new Estes HEX-3 kit I didn't think of an odd-ball rocket.
HISTORY: This isn't the first card stock rocket kit. Centuri had their Two-Bits, Vulcan and X-24 kit back in the 1970s.
I saw the girders printed on the sides and was reminded of the original Porta Pad launcher.
HISTORY: The first Porta Pads were yellow then later orange. An all chrome version was in the Citation line starter set.
Here's my take on adapting the Porta Pad legs to the Hex-3 style design.
I didn't buy the Hex-3 kit, I enlarged the parts picture from the Estes website and drew up my own version. (Sorry, I can't email these drawings.)
Looking at it now, I should have made the center piece just a six sided cylinder, not a cone shape. The white "holes" in the legs could have been smaller. Oh well, the old timers will get it.
From the underside -
A heavy mat board support ring was cut. There is no need for an internal launch lug. The rod simply slides through the hole in the bottom ring beside the engine tube then through the split 20/50 ring at the top.
