BirdKit's modular ornithopter gearbox makes it much easier to build a large RC ornithopter on your own. The gearbox is now offered as a set with motor and wings.

The ornithopter gearbox is 3 inches tall. It's suitable for RC ornithopters weighing about 1 pound (0.5kg) with a 4 to 7 foot wingspan. The gearbox is designed to fit in a hollow fuselage. You can build your own fuselage using traditional balsa wood construction, and a fiberglass body is also available.

The carbon fiber studs on the gearbox have a 0.240 inch diameter, designed to fit the hollow carbon fiber wing spars. The gearbox assembles quickly with screws. The gearbox sides are made of a durable G10 composite material, and ball bearings are used throughout.

The gearbox is sold with a powerful brushless motor that is matched to the gearbox. The motor may differ from the photos/video. A 3 cell lithium polymer battery is recommended. The gearbox comes with a set of five pinion gears: 16, 18, 20, 22, and 24 teeth. This allows a range of gear ratios from 28:1 to 42:1.

The wing set is sewn from white high performance fabric and includes hollow carbon fiber wing spars. It has a 68 inch wingspan.

Building your own ornithopter is much easier with the ready made gearbox and wings. Order one today and get started on your next amazing project!
