An all around low-wing sport model based off a 1970’s classic.

The Sky Ranger 40 is as much fun to build as it is to fly. Using updated design techniques and laser-cut precision, we’ve designed this kit so most any modeler can successfully build it in a short amount of time.


This all-around sport model’s retro design looks great in the air and makes you look like an ace pilot. Loop it, roll it, spin it, snap it, and just have a great time flying it.

Power the Sky Ranger 40 with either an electric or glow powerplant.


We’ve designed the fuselage with a built-in hatch so you have quick access to either your LiPo batteries or fuel tank. The wing is removable via two bolts from the underside of the model.

Our Sky Ranger 40 was reviewed by Terry Dunn in Model Aviation magazine. Check out his video report below...





A Great Sporster
Whether you like gentle cruising, or prefer to tear up the sky, the Sky Ranger 40's wide flight envelope makes it a blast to fly!


WEB-LOCK Construction
There's nothing else like it. Build our wings, straight and true - with a minimum amount of fuss.


Premium USA Hardware
Included in each Old School Model Works kit is a premium hardware package. We only source our hardware from brand-name, USA manufacturers to guarantee the best quality.


Rugged 3/16" Main Gear
We include sturdy, pre-bent main gear and wheel collars. The 3/16" diameter wire can absorb quite a bit of abuse for those no-so-good landings.


Front hatch
Held in place with magnets, this hatch gives you easy access to batteries or fuel.


Also included is a clear, pre-formed plastic windscreen.

We are sorry, but due to the size of the kits and high International shipping costs, we cannot ship them outside of the United States.
