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.
