Diana 3 RC Glider – Elegance and Performance in 1:4 Scale

The Diana 3 is far more than just a model glider — it’s a high-end, 1:4 scale replica of the renowned competition motor glider developed by Diana Sailplanes. Designed by Glider_it, this version captures the sleek lines and distinctive features of the original, and even allows for electric motorization using an FES (Front Electric Sustainer) system.

With its modified HN airfoil, this model offers an impressive speed range and excellent stability across flight conditions — whether soaring in thermals or flying fast and dynamic. The Diana 3 is ideal for experienced pilots and scale enthusiasts looking for both performance and premium build quality.

Why choose the Diana 3?

  • Full composite kit with a fast and clean assembly: simply glue in the control horns and install your servos.
  • Flaps and ailerons come top-drive ready and are pre-hinged in the mold; the elevator is also pre-hinged.
  • Built to offer high-quality craftsmanship and user-friendly assembly for a smooth setup experience.
  • Optional features include a fuselage ready for retractable landing gear and a canopy pre-mounted, painted, and ready to install.

Available in two versions:

  • FS: Fiberglass wings with carbon spar and a single layer of heavy carbon – strong and reliable.
  • FS Performance: Fiberglass wings with carbon spar and a single layer of light high-modulus carbon – ideal for lighter weather conditions or more refined flying.

Price: €1990 ( 20% french VAT included)
(Applies to both versions)

Customization and accessories available:

  • Tailor-made transport bags
  • Custom paint schemes
  • Deluxe fuselage
  • Visible carbon finish option

The Diana 3 quickly became a standout in the high-performance glider scene and remains a top choice in the RC soaring world. If you're looking for a model that combines realistic scale looks, aerodynamic efficiency, and easy assembly — this is it.
