I AM NOT SELLING A KIT, only a 40" Berkeley SINBAD 40 kit PLAN & PARTS PATTERNS enlarged to a 93" wingspan.

To make this enlargement possible I carefully split the plan page, with sufficient overlap, to give you two very large plan pages. The size of these prints is impressive! Just take a look at the first plan picture to see my classic 4’ Panel Stick AND a 3’ yardstick diagonally across the plan pages.   

I also offer the Berkeley SINBAD PLAN at its original 40” wingspan, and an enlarged 60” span.

As a BONUS I include a copy of Frank Zaic's vintage Flying Models article on THERMAL HUNTERS---how to fly towline gliders successfully.

YOU ARE PURCHASING NICE, CLEAN, WHITE, FULL-SIZE COPIES OF THE ENLARGED PLAN SHEETS FOR THE SINBAD 40, + ENLARGED PARTS PATTERNS FOLDED AND IN A MANILA ENVELOPE.

So, if you, too, have long wanted to build a very large SINBAD glider---and add rudder or rudder & elevator RC, here is your chance.
