RC ornithopter. You can purchase the gear unit separately
to use in your own RC bird. The RC ornithopter gearbox comes
complete with a high-efficiency AXI Gold Line 2208/20 motor.
RC ornithopter gearbox will accept different size pinion gears
ranging from 16 through 24 teeth. This allows a range of gear
ratios from 28:1 to 42:1. Use a smaller pinion gear for larger
wings. Use a larger pinion gear for small wings and more rapid
flapping. A 20-tooth pinion gear is included.
how to make an ornithopter is much easier with this ready
made gearbox! You can build your own fuselage from balsa wood,
or use fiberglass like our Crossbow
RC ornithopter kit.
