You've done great with your first trainer and you still have a perfectly good .40 size engine and 4-channel radio. Now is the time to step-up and start having some real fun. SIG's Four-Star 40 has been the "second airplane" of choice for thousands of modelers since its introduction. 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.


When developing the FOUR-STAR 40, there were two main design goals. First, of course, was impeccable flight performance in the SIG tradition. 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 - you will give this kit a "four star" rating!

SIG Four-Star 40 Kit
All the parts were there. Everything cut really well. Directions are a breeze to follow. Can't think of anything bad to say about kit. Don't have it done yet, so I can't say it will fly,but it looks like it will.
