This is the same modular gearbox that appears in the Crossbow
RC ornithopter. You can purchase the gear unit separately
to build your own RC bird.
ornithopter gearbox is 3 inches tall, and it's suitable for
ornithopters weighing about 1 pound (0.5kg) with a 4 to 6
foot wingspan. The gearbox is designed to fit in a hollow
fuselage, which you can build easily using traditional balsa
wood construction with a 1/8" plywood floor for mounting
the gearbox. A fiberglass fuselage or single beam construction
could also be used.
carbon fiber studs on the gearbox have a 0.240 inch diameter
that will fit some of the lightweight, hollow wing
spars made for kites. You can also use kite fabric for
the wing surface. The gearbox requires assembly.
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 application. 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 gear for small wings and more rapid
RC ornithopter gearbox is designed to use a high-efficiency
Gold Line 2208 series brushless motor. Recommended motors
are the AXI 2208/20 with two cells, or the AXI 2208/34 with
three cells. These motors have the correct power output and
mounting specifications for use with the ornithopter gearbox.
your own ornithopter is much easier with this ready made gearbox.
