An easy-to-handle, quick-building, great-looking design that’s quite aerobatic.

The Sport Air 40 stands out as one of the more visually appealing aircraft in the 40-size market, thanks to its clean lines and striking resemblance to several full-scale light aircraft.

This excellent all-around sportster will attract many favorable comments at the flying field, not only because of its good looks, but also because of how great it flies.

As with every Old School Model Works kit, our Sport Air 40 is a build-it-yourself airframe, designed and laser-cut from high quality balsa wood and light ply.

Included are new, simplified building features as well as laser-cut precision and self-aligning parts to make this all-time favorite even better. For example, our exclusive Web-Lock construction makes building the wing panels a snap. Rather than the sheer webs being an afterthought, they are utilized during the build to properly space, position, and lock in each rib.

We have completely updated the airframe with laser-cut and self-aligning parts. The fuselage is built around a self-aligning, light-weight box for added strength. Surrounding this is the outer balsa skin, which is strong, light-weight, and twist-resistant even when performing high-stress maneuvers. The balsa/ply airframe makes the Sport Air 40 uncomplicated, lightweight, and easy-to-build.

 

Power can come from glow or electric powerplants. We've designed the fuselage with a magnetic top hatch, so you have quick access to either your fuel tank or batteries. Also the tray can be removed to give access for mounting an ESC or flight pack battery.

Another thing you’ll notice is that the Sport Air 40 has a bit more ground clearance than a typical 40 sized design. It’s longer landing gear give you the ability to easily fly from grass fields.

When it comes to aerobatics, the Sport Air 40 doesn’t disappoint. While it may not be as precise as a dedicated pattern bird, it is incredibly forgiving and can easily perform a wide range of maneuvers. Even with the controls increased for aerobatics, landings are one of the Sport Air .40’s strong suits, due to its excellent low-speed stability.

Thinking of going electric?

We have teamed up with Innov8tive Designs to provide suggestions for anyone wanting to convert our OSMW kits to electric power. Innov8tive is a well known and very reputable supplier of high quality electric motors, ESC's, LiPo battery packs as well as other products.

They have provided us this list of suggested motors, ESC's, batteries and props for each of our kits. You'll find that information, along with their computed specs (watts, RPM, thrust, etc.) when using either their BadAss or Cobra power systems. The Cobra power systems are usually less expensive and the BadAss systems are typically have the higher performance. Both choices are shown so you can choose between these brands and pick the one that's right for you.
