Compiled from Real World High Definition Audio Recordings. Genuine and historically correct Wright R-3350 Duplex-Cyclone engine sounds inside and out. Smooth power band changes from idle to full power. Start-up sounds timed perfectly with the smoke belching from the exhaust. Interior and exterior sounds are balanced and true to the real sound of the aircraft. Autopilot, roll, touchdown, flaps, exit door, wind slip, gear alarm, cockpit ambiance, reversers, gear, stall.Nice solid cruise sound with that authentic "Connie Note" that is unmistakeable.This sound-set can also be used for your Boeing B-29 Superfortress. May also work for the Fairchild C-119 Flying Boxcar. The sound-set has been produced to fit the real life feel of the Connie as much as possible within the confines of the simulator. A great addition to any of your Historic Connie Fleet.
