plane v1

Rules, spec, progress log, and demos.

Goal
Stable glide with simple control: rudder + elevator only. This is a trainer-style platform, not a performance build.
Rules
  • High wing
  • Straight wing (no delta, no forward-swept)
  • Big dihedral (~5–7°, target 7°)
  • Rudder + elevator + motor
  • CG target: 25–30% chord
  • No ailerons
Design notes
  • Adjustable battery position for easy CG tuning
  • Replaceable belly skid (no wheels for prototype 1)
  • Print: eSUN LW-PLA
  • Infill: gyroid (tentative)
What’s next
Finish the full wingspan and start the fuselage layout after the calipers arrive.

Next steps.

  • Finish the full wingspan and decide the wing join method.
  • Lay out the fuselage internals first (battery, RX, servos) to lock the body size.
  • Design the adjustable battery tray so CG can be set between 25–30% chord.
  • Design a replaceable belly skid.
