Corkscrew 80

This kit has two optional features.

  • Plywood F3 for use with a nylon engine mount
  • Ribs cut for use with 3/32 leading and trailing edge sheeting and cap strips

Choose the alternate version or the standard version for each item.  On the alternate wing, the leading edge is 1/2″ balsa.  In either case, the spars are 1/2″ wide rather than the unusual 9/16 called for on the plan.

My laser cutter doesn’t like 3/8″ balsa, so you cut out the tail yourself.  Or if the balsa company sends you super hard 3/8″ sheet, cut it into sticks and build the tail from sticks.  Wing saddles are notched for a 1″ x 3/8″ bolt block.
