FSX – Helicopter Radial Engine Sound Update

FSX – Helicopter Radial Engine Sound Update. This is an update to the H-21 sound file. It no longer cranks every 30 seconds when in outside views. It is great for radial engine helicopters like the Piasecki H21, Sikorsky CH-34, S-55, S-58, and Mil MI-4. By Michael E. Roberts.
