Those of you flying this neat FSX radial trainer may have noticed two problems associated with fuel: first is that the fuel gauge in the VC does not work, and second is that the engine quits due to fuel starvation after about 40 minutes of flight at cruise power setting.
Turns out that V/AS got the fuel load and location correct, but mapped the gauge to the wrong fuel tank data source. The attached "aircraft.cfg" file corrects that error, and brings the fuel gauge to life. While I was at it, also modified fuel burn rate to give approximately correct endurance.
To install, first backup your current "aircraft.cfg" file in your "SimObjects/Airplanes/ALPHA Yak-52" folder just in case, then unzip this new "aircraft.cfg" file into the same location.
