I completely gave up on this topic, GCat is never going to release any of these. I dont know why you people are still waiting around.
You don't see that he is making progress?
ALSO... (I know that you probably don't like to take suggestions, Gravity, but this might save a LOT of time).
Gravity, why don't you just use stratto's spitfire engine script. You know, the one that changes the engine acceleration sounds due to the speed (I think?) of the plane. Use that for your sport sabre.
EDIT: Since stratto is not involved in blockland anymore, and probably never will be ever again, I'm assuming you won't have to ask.
