The objective of SimplePlanes is to design and build various flying vehicles using an array of parts. Players can experiment with aerodynamics and physics to see how their creations perform in flight.

To build a plane, open the vehicle designer, select a body part, and then add wings, engines, and other components. You can adjust their positions and angles to achieve the desired flight characteristics.

SimplePlanes features several game modes, including sandbox mode for free building, challenges to complete specific tasks, and a career mode with missions and objectives across different environments.

To enhance flight stability: 1. Ensure that the center of mass is aligned with the center of lift. 2. Adjust the wing position and angle for better aerodynamic balance. 3. Use control surfaces effectively to manage pitch, yaw, and roll.

Yes, you can share your creations by exporting them and sharing the file. Other players can then import your design into their game, allowing for community sharing and collaboration.
