Cut EDF jet & RC foam wing cores — free

Ready-to-cut wing presets

Every preset below opens in the tool with the full recipe — airfoils, chords, span, sweep, washout — already filled in. Load one, tweak it to your build, and cut. Each cuts one panel: make a mirrored pair for a complete wing.

What the wing generator does

• NACA 4-digit + named airfoils — type any NACA code, or pick MH 45 / MH 60 / PW51 / S5010 (reflexed, for flying wings), Clark Y, E205, S1223 or RG-15.
• Taper & blend — different root and tip chord, even a different tip airfoil; the 4-wire cut morphs between them.
• Sweep & washout — leading-edge sweep in degrees, and tip washout (twist about the ¼-chord) for gentle stalls.
• Spar tunnel — a round carbon-tube tunnel with a thin entry slit, at any % of chord, sized to your tube — the cut nobody enjoys doing by hand.
• Honest preview — watch the wire path in 3D before any foam is harmed, including the cut time at your feed rate.

From preset to flying wing

1. Load a preset (or generate your own) — the tool sizes a material block to fit.
2. Check the cut preview and the X/Y + U/V plane viewers.
3. Export G-code, or stream straight to an ESP32/FluidNC controller over USB or Wi-Fi.
4. Cut the second panel mirrored, join at the root, add your spar — go fly.

Frequently asked questions

Can a hot-wire CNC cut a jet wing?

Yes — hot-wire is the standard way to cut foam wing cores. A 4-axis cutter morphs between the root and tip profile, so taper, sweep and washout all come out in a single pass. Every preset on this page cuts as a 4-wire morph.

What about flying wings? NACA airfoils have no reflex.

The wing generator includes true reflexed sections (MH 45, MH 60, PW51, S5010) sampled from published coordinates, alongside the NACA 4-digit formula — so flying-wing and plank cores need no workaround.

Do the presets include a spar slot?

The presets are clean cores; the generator has a spar-tunnel option you can switch on after loading one — it cuts a round carbon-tube tunnel with a thin entry slit at any % of chord, sized to your tube.

Do I need to cut two wings?

Yes — one panel is half a wing. Cut a mirrored pair (flip the foam block, or swap the tower columns) for the opposite side. The generated G-code carries a reminder comment.

Is it really free?

Yes. The CAM, the generators and every preset are free with no signup — design, simulate, export or stream to an ESP32/FluidNC or GRBL controller.
