This is actually a project you could do yourself.

Rick Salsala has a Tracker out there. I'm not sure if it's a turboprop, so you may have to make due with the radial engined version. I'm pretty sure you can download that here.

All you'd need to do is add effects to it. For ideas on how to do that, download other fire bombers and/or airshow smoke. You can get those here also.

Look in their aircraft.cfg files under the effects section. You will need to do some trial and error, but you will ultimately come up with exactly what you want.

Good luck!
