didn't take it as such mechanic - was going to look and see if the damage file might have been a higher sampling rate, or different bit depth...that's all
Need a bug report forum for the pack
Try importing a damage1.wav from one of the other aircraft folders into the hurri1 folder. I noticed that the "default" damage1.wav is about 10 seconds long, and that could cause the lag, as well as the engine off wav is a little long as well.
Possible fix, if your up to it, is to shorten those two files or rename the stock damage1.wav to damageold.wav - then change the file damage2.wav to damage1.wav.
I'll look further into it... the hurricane series as well as some of the british planes are ones that I haven't spent too much time on lately...
Undertaking the accurate rate of fire sounds for the guns took awhile, but with the site up and running it will be easier now for me to pay closer attention to individual plane sounds. It will make it easily updated as I configure/record/edit new sounds for a plane set. I also plan to go back to a stock sounds settings in the sound level setup, where there is less discrepancy between levels per effect per plane selection
