Enstrom Helicopters announced that the flight test program for its two-seat TH180, currently in development, is progressing on schedule with the second prototype building flight hours. “We are into the envelope expansion phase,” said Enstrom test pilot Bill Taylor. “We’ve had it out over 90 knots so far, and everything is performing as expected.”
A third, fully conforming prototype is currently being built at the factory in Menominee, Michigan. That airframe is expected to take to the skies later this year.
