Thought I might bring to this thread my experience with Tigers flybys. To start with I know Tiger has moved on but I want to thank him for his dedication and time he invested making his sound mod. thankyou. I have enjoyed his mod from its start, even sadly having to disable it when IL-2 was updated in its versions and it became incompatible. And then he updated his mod for HSFX 6 and we were back with those great flyby sounds.(His sounds not the hsfx jsgme ones). Since then many have tried to use the mod with half success. I have seen in this thread some very smart work arounds, some I tried which did let the flybys work but!! not 100% plug and play. So I took some ideas away from reading this thread and made my own fix for tigers flybys in HSFX 7.03. I understand a fix for this mod was introduced but it had failings.
1: Not all planes had flyby sound, and some planes would lock the game when trying to view external, others would freeze the game at 100% load
2: Sound prs names have changed a lot since tigers mod so many of his sounds just wont work, simple as that.
3: All I wanted was those cool flybys rattling through my headphones

So with this I started out to try and come up with a more workable solution to having working flyby sounds in my HSFX install. I will add here that I did try the hsfx version of tigers flybys but the way they enable them in the game was different to tigers and A- I felt they were a watered down version and B- it conflicted with a favorite mod (Level Stabilizer for all) so on with the thinking cap.
So after a week or so I have now a working tiger flybys with both props and jets and no stuffing around with enable/disable jsgme mods etc. My game as I said is HSFX 7.03 and I do have other mods installed. I dont use sas engine mod and any mods I use I enable with jgsme straight to the Files folder and nowhere else. Sorry I do use the MODS folder for Dif fm only.
Where to go from here, well I would need permission to share and thats that as I have made adjustments to one of tigers class files. The other parts are already available on the net.
If I get that permission then I will post my method and make avaliable the classfile
In closing I give a big thankyou to all modders big and small for making this sim what it is today. It's a pity that the online days are behind us, I was in a squad for many years and lived for those times, what a blast!, but I still enjoy firing up the game offline for a hour or so.
