Diamond HK36 Dimona Aircraft under $500,000

The Diamond HK36 Dimona (and Super Dimona / HK36 TTC) is a two-seat composite motor glider — a powered sailplane combining a piston engine (Rotax 912 on most variants) with long, high-aspect-ratio wings for engine-off soaring. Originally designed by Hoffmann Flugzeugbau (the "HK" designation) and continued by Diamond, the Dimona is used for glider training, soaring, glider-tug operations and economical powered cross-country flying. Some wings fold for hangar storage. A niche but well-regarded platform in the motor-glider segment.

  • Avionics — typically basic VFR; verify ADS-B Out if required in your airspace.
