What it makes
The RC and Robotics studio draws the flat parts that hold a model or a robot together. Type the size, pick the part, and export a cut-ready file. Spar notches, lightening holes and mounting holes are placed for you.
Parts you can make
| Part | What you set |
|---|---|
| Wing ribs (NACA airfoil) | Airfoil, root and tip chord, number of ribs, spar notches, lightening holes |
| Fuselage formers | Width, height and number of formers along the fuselage |
| Boat hull | Length, beam and depth: bulkheads plus a slotted keel |
| Robot chassis plate | Size, motor, caster and controller board holes |
| Servo mount plate | Servo size and count |
| LiPo battery tray | Pack size and strap slots |
| Motor mount firewall | Motor hole pattern |
| Control horns | Size and hole spacing |
How to use it
- Pick a part from Aircraft, Boats or Robots.
- Type your sizes. The preview redraws as you go.
- Check the holes against your real part, then export for your laser.
Tip: cut one rib or one mount first and test-fit it on your spar, servo or motor. Then cut the full set.
Reading a NACA airfoil name
The four-digit NACA airfoils describe their own shape. In NACA 2412, the first digit is the maximum camber as a percentage of the chord (2%), the second is where that camber sits in tenths of the chord (40% back from the leading edge), and the last two are the maximum thickness as a percentage of the chord (12%). An airfoil starting 00, like NACA 0012, is symmetrical: no camber, the same shape top and bottom, which suits aerobatic models and tail surfaces.
| Airfoil | Shape | Typical use |
|---|---|---|
| NACA 0009 to 0012 | Symmetrical, 9 to 12% thick | Tail surfaces, aerobatic wings |
| NACA 2412 | Gently cambered, 12% thick | General-purpose sport and trainer wings |
| NACA 4412 | More camber, 12% thick | Slower flying, more lift |
On a tapered wing, each rib has a different chord between the root and the tip, so it pays to cut ribs as a numbered set and keep them in order. Balsa and light plywood are the usual rib materials; check that your laser cuts them cleanly with a test card, and see the wood guide for thin sheets. Gears for robot drives come from the gear generator, and enclosures for the electronics from the enclosure and panel generator.
Questions
Which airfoils can I use for wing ribs?
The wing ribs use NACA 4-digit airfoils, such as 2412 or 0012. Set the root and tip chord and the number of ribs, and the studio makes a tapered set with spar notches and lightening holes.
Do the servo and motor holes fit my parts?
The hole patterns follow the common published sizes, such as SG90 and MG996R servos. Parts vary between makers, so measure your own part before cutting a full set.
What material should I cut RC parts from?
Balsa and light plywood are the usual choice for aircraft. Robot chassis plates work well in 3 mm plywood or acrylic.
Can I make a boat?
Yes. The boat hull product makes bulkheads and a slotted keel for a hard-chine hull that slots together before you skin it.
Does it work with my laser?
Yes. Every part exports as SVG, DXF or PDF for diode, CO2 and fibre lasers.
