Looking for rocket smoke mod

[dresoccer4]

hey everyone. i'm flying new DCS 2.2 NTTR, and was shooting some unguided rockets out of the harrier, and thought to myself "hmm, the smoke trails on these seem really short."

 

i counted and it totally disappears in ~3 seconds. i tried searching but couldn't find a mod out there to increase their duration. anyone know of any?

 

thanks!
