Hi Josh,
Do you mean you want te same gun sounds in the SkyUnlimited Hurricanes, as the ones we have in the ETO hurricanes? ie the 8 x Browning sounds..
If so you need to edit each of the xdp files found in each aircraft.
If you open the xdp file with notepad, at the top of the file you will see text like this:
<?xml version="1.0"?>
<UnitData>

This is where the weapon type is specified. you can see in teh above text I have made one section green, this is the weapon being called for by the SU Hurricanes. if you edit the xdp files so that the weapon being called for is
AvHistory_gb_gun_8x303cal
then you will hear the new ETO 8 gun sounds when you fly the SU Hurricanes.
So an example of what you xdp would look like is this:
<?xml version="1.0"?>

you can see where I have changed the gun type in green.
To get the same engine sounds just copy teh sound folder from one of the ETO Hurricanes and place it into each SU Hurricane folder.
remember to back up your original files before editing.
HTH's,
regards Rob.
PS if you get stuck let me know and I'll edit a set of xdp files for the SU Hurricanes and email them to you.
