Enter mission and span → get a realistic weight range
Design starts with intent. But intent needs a starting point. Before defining surface or loading, you need a plausible flying weight.
This tool gives a simple weight range based on mission and wingspan. It is not a performance guarantee. It provides a coherent baseline so the rest of the method remains practical.
Pick your mission, enter wingspan, and use the output weight range to move forward into wing surface and planform decisions
Mission Weight Estimator
From here, wing surface and wing loading can be defined coherently.
RC Plane Designer evolves as chapters are refined and connected.
The project began as a personal notebook used while designing scratch-built RC airplanes.
