This is an update for FSX of the Su-27B/UB/Su-30MKK Russian Package by Bill Wolfgen. I have updated the flight dynamics, added the 4th wheel, given it a 2D panel, and changed the afterburner and smoke effects. You need the original aircraft for this update to work. No VC. Unzip to a folder of your choice. Back up your air and aircraft.cfg files and replace them with the ones in this folder. Do the same with the panel folder. Copy the effects to the main FS effects folder. Copy the pictures with the long names to the aircraft folder. If you have not already done so, copy the .cab files from the default aircraft panel folders that have them to the main FS gauges folder. For some the .cab flies will be .zip files, as .cab files are a type of zip file. See [reference speeds] section of the aircraft.cfg file for operating speeds. Anyone: You have my permission to use any of my updates with the following conditions: One, you don't try to make money with them. Two, you don't try to hurt, or take something from anyone by using them. Bob Chicilo. bchicilo@jet2.net
