This is a tribute to John Carroll, one of the co-conspirators in Holverson Designs and Fun Rockets. It’s a 1/5scale recreation of the Tangent and the Aero-Pad. They’re a bit kludged for scaled down 3D printing. The Tangent was a Holverson Designs kit that was more John’s design than Holverson. The Aero-Pad was an unproduced Fun Rockets item that John was involved with. The launch rod is a 7.2” long piece of 1/16” diameter wire.
