Foam RC Trainer CAD Design

I’m putting together a compact, beginner-friendly RC trainer built entirely from 3 mm XPS/Depron and need a complete digital package to finish the concept. The model has a 50 cm wingspan and must fly slow, stay rock-steady in level flight, and launch comfortably from a hand-toss without stalling. It will run a small outrunner brushless motor on a 3-cell Li-Po, so please keep wing loading low and incorporate generous dihedral and ample tail volume for forgiving handling.

You’ll be working in Fusion 360—I’ll need the native file plus exports—and I’m after a full detailed design, not just basic ribs and spars. Every component that matters for a clean build should be there: interlocking fuselage formers, removable wing, servo pockets, battery tray, motor mount, pushrod routing, and any small reinforcement details that make life easier for a first-time builder.

To gauge performance and finalise centre of gravity, I also want a quick but solid XFLR5 analysis (polar graphs and stability derivatives are enough) along with a CG spreadsheet or annotated drawing that shows the target range with a 3S 450–850 mAh pack.

Key deliverables
• Fusion 360 file (plus STEP/DXF exports)
• Printable foam-cutting templates laid out on A4/A3 sheets
• CG calculation sheet or annotated diagram
• XFLR5 project file and summary PDF of key plots

Acceptance
The design should slot together from flat-cut parts without hot-wire shaping, balance at the calculated CG with a 3S pack, and hit a predicted wing loading under 80 g/dm². Provide me with a short build note or screenshot set proving the parts fit correctly in the CAD assembly.

If everything looks good in the review pass, we’ll sign off and I’ll start cutting foam right away.
