BirdKit's modular ornithopter gearbox makes it much easier to build a large RC ornithopter on your own.

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 that will fit our carbon fiber hollow 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 comes with a set of five pinion gears (16, 18, 20, 22, and 24 teeth) so you can select the best gear ratio for your particular ornithopter. This allows a range of gear ratios from 28:1 to 42:1. Use a smaller pinion gear for slower flapping, larger wings. Use a large pinion gear for small wings and more rapid flapping. The available ratios can accommodate a 4 to 7 foot wingspan.

All gearboxes are sold with a powerful brushless motor that is matched to the gearbox. Motor may differ from photos/video. A 3 cell lithium polymer battery is recommended.

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