SIG's Four-Star 40 has been the "second airplane" of choice for thousands of modelers since its introduction in 1989. With its low semi-symmetrical wing and light wing loading, the Four-Star 40 takes you to the next level, with all the free-style aerobatics and whoop-dee-doos your thumbs can conjure up. Four-Star 40 Model Airplane
Four-Star 40 Model Airplane When developing the FOUR-STAR 40, there were two main design goals
First, of course, was impeccable flight performance in the tradition of all SIG kits.
Second, it had to be ultra-simple to build without looking like a "box with wings".
The FOUR-STAR 40 shines in both respects! Give it a try - we think you'll give this kit a "four star" rating!
Optional Molded Plastic Wheel Pants for the Four-Star 40 Kit.
