Load into your simulator with that aircraft at any airport you choose. Go to the menu at the top of your simulator and click the Add-ons menu. In the drop down, click GSX, then click Customize Aircraft. Use the aircraft editor to input all the information I have posted for that aircraft. Make sure you save it.
You can test it by being in a parking spot big enough to accommodate that aircraft. Press Ctrl+F12 to bring up the menu and choose whatever option you want. To speed things up, increase your sim rate.
