Pick a wingspan and a flying style — get a complete plane design with a to-scale drawing you can flip between 2D plan and 3D view, plus a parts list. Want more control? Open Advanced for aspect ratio, taper, weight, and dihedral.
Results are a proven starting point for foam-board builds, not a guarantee — always range-check your gear and maiden with extra altitude.
Set your wingspan and style, then hit
Design My Airplane
Every number here is a proven starting point that flies — the same sizing rules behind the builds on my YouTube channel. You'll still fine-tune the balance point on your maiden flight (start slightly nose-heavy, never tail-heavy). When your design is done, the Checklist Builder sizes your full parts list and the Wiring Designer shows how everything plugs together.
Want to go deeper than a starting point? Foam Flight Lab is my design sandbox — drag a slider and a 3D plane rebuilds itself while it solves the neutral point, static margin, tail volume, stall speed and roll rate. This page gets you a plane that flies; that one lets you understand why.
You've got a design and a CG. Now get a matched motor, ESC, battery, prop and servo set sized to this exact plane.
