Trainer-like stability. Sport-Pattern performance. Quick and easy to build. What’s not to love?!


Designed as a first low-wing trainer over five decades ago the Lark is still a terrific, everyday sport plane. Our version of the Lark keeps all of the iconic looks and great flying characteristics of the original. Plus, because it combines docile flight characteristics, trainer-like stability and an aptitude for super-smooth, exciting aerobatics, the Lark is just what you need to step forward with your flying ability.


Our kit has been designed to keep building time to a minimum and introduces new, simplified building features as well as laser-cut precision and self-aligning parts to make this all-time favorite even better. Building the wing and stab are a snap as all of the ribs include tabs which allow you to quickly and precisely align them on your building board. Did we say stab ribs? Why yes we did, as we integrated the original airfoil shaped stab into our design as well.

The fuselage is built around a self-aligning, light-weight box for added strength. Surrounding this is the outer balsa skin that is strong, light-weight and twist resistant. Importantly, this balsa/ply airframe is uncomplicated, lightweight, easy to build, and features precision laser-cut parts that fit together quickly and accurately.



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.



In the air, the Lark is an aerobatic, yet forgiving design that makes it the perfect entry-level low wing airplane. It’s also great for experienced pilots because it packs a fully aerobatic capable design into a small package that can fit in the trunk of many cars, completely assembled.

When flying at slower speeds, it's a great way to relax, shoot touch-n-goes and enjoy low passes down the runway. But throttle it up and the Lark is just at home as an entry-level sport-pattern ship. Loop it. Roll it. Thrown in some Cuban 8’s and even some hammerhead turns for fun and you'll enjoy every minute of it.
