Andy73 3 Posted May 28, 2012 Sound Upgrade for Rotary Engines View File Hi As promised, here's my Update for almost all Planes in OFF with Rotary Engines. New Startup and Shutdown Sequences included. These Startup Sequences are NOT included in Olpaint's JSGME Version, but you can install and use them very easily. Installation is easy. Let's say for Example you want to upgrade the Sopwith Camel. Open your OFF Installation. Then got to: Aircraft / Camel_sqd / Sound Simply copy the new Samples into this Sound Folder. Overwrite the old ones. Please make it the same way with all other Planes from this Download. Thanks to OBD Software for the Original Stuff.
