Sig Manufacturing Co. is a name that everyone in the aeromodeling hobby should know. In fact, Sig celebrated 60 years in business in 2014! With such a long-standing commitment to model airplanes, it’s no wonder that the company continually develops great new products.

Sometimes a new product can be a remake of an earlier aircraft—that’s where the Somethin’ Xtra enters the story. This aircraft has been around the block a time or two. It’s still available as a kit, and was previously in Sig’s lineup as an Almost Ready to Fly (ARF) aircraft.

At the 2014 Toledo R/C Expo, Sig unveiled a new version of its classic airframe: the Somethin’ Xtra EG. The EG signifies that the new version can be powered by either electric or glow power. With the ever-growing number of modelers who enjoy electric flight, the Somethin’ Xtra is getting yet another go-around!
