Some of the turboprops. The Saab 340s I'm flying, we do a lot of flaps 0 takeoffs, but because we usually have 9,000 ft runways. the only time we use flaps, is a flaps 15 t/o out of Key West, that's about 4,800 ft long.
It's a great build, just one little critique. Airliners normally don't rotate that far down the runway, we're 100-200' above that part of the runway.
