RC Plane Endless Wing Building Rack

thingiverse

You'll need two lengths of 15mm copper pipe to create the RC plane endless wing building rack, as long as you need it to be. A pile of M3 x 30mm bolts and lock nuts is also required. There are four lock nuts per crossbar needed, which should be gently tapped in since the holes for them are tight enough to keep them securely in place. The two end supports are bolted through the pipe, while the mid-supports require two small self-tappers each and are screwed to the pipe before being attached to a workbench or board to keep the rack straight and true.
