Record Breaking Ornithopter by Ray Harlan

A free flight rubber powered ornithopter designed and built by Ray Harlan. This is a unique bi-wing canard
design intended for duration indoor flights using ultralight construction.
Ray's ornithopter achieved a record time in Cat IV -(Buildings with a ceiling higher
than 30m or 98'-5") of 19min 45sec in 1995.
Roy White currently holds the Cat IV record at 21m44s.
This demonstration flight took place at Lakehurst in Hanger No. 1 with a ceiling
height of over 170 ft. Ray is using a partial motor. The clip begins
with Ray winding the rubber motor to the desired torque, carefully mounting the loaded motor onto
the frame and launching it.
