is the original easy to build ornithopter. It was designed
by Nathan Chronister in 1993. The Freebird has introduced
thousands of students and hobbyists to the engaging pursuit
of building their own flapping-wing flying machines. Other
tutorials and model kits have imitated the Freebird design,
but they don't always use the correct, lightweight materials.
Building from the authentic Freebird design gives you the
best chances to achieve success.
