The Legend Gets Bigger . . .

 

Thousands of modelers just like you have already built and flown the SIG FOUR-STAR 40, making it one of the most popular R/C models on the market. Now we've taken all of the unique design features of the FOUR-STAR 40 and reproduced them on a grander scale.


The FOUR-STAR 120 has a near perfect blend of simple construction, classic looks, and outstanding flight performance.

Easy to build lite-plywood fuselage construction, fast building wing, pre-shaped balsa leading edges.
With a wing loading like a trainer, the FOUR-STAR 120 is easy to fly yet will perform all the free-style aerobatics your thumbs can keep up with.

The impressive size of the FOUR-STAR 120 (IMAA legal) makes for smooth aerobatics and ultra-slow landings.

Quality hardware pack includes landing gear, canopy, engine mount, pushrods, hinges, decal sheet, etc.
