With the freely downloadable templates, its easy to configure an entry for your airplane. Just enter the basic empty weight and arm, and you are ready to enter weights for your next flight to get accurate W&B calculations. You can e-mail a PDF of the flight W&B, so you can easily get printed copies or share. You can also calculate W&B for arrival (after fuel burn), not just departure. If you have a unique aircraft, you can create your own template. I cant think of a missing feature.
