This is an update for FSX of the SU-15F by Brett Hoskins, Mike Mahat, and Bennett Gray; with updates by Philippe Wallaert and Michael Pook. I have added gauges or changed gauge positions as well as some of the window positions; added the 4th wheel; corrected the contact points; changed the afterburner burners; changed the smoke; and updated the flight dynamics.
