Here is a simple script I wrote to sweep the wings of the F-14D Super Tomcat recently released by SkylineGTRFreak.
Credit to Kevin D. for the screenshot
At approximately 200 knots (~100 M/s) the wings will sweep backwards, below that speed the wings will extend again if you are not touching the throttle!
The speed is configurable by changing the part that says
if GetEntitySpeed(veh) >= 100 then change the 100 to whatever speed you would like (the speed is in metres per second so keep that in mind)
In order to add another model or change which one is used change the config section in
sweep2.rar (1.0 KB)
Github Code for you as well.
/sweep Will toggle automatic wing sweeping.
/wings Opens or closes wings based on current state
