For Sale is a 1660mm diameter DUC SWIRL-2 ground adjustable carbon propeller.  Removed from a CH750 STOL / Jabiiru 3300.  125HP, 3300 rpm, embedded nickel leading edge.  $2800.

The propeller is extremely smooth and balanced in all rpm settings.

The DUC  propeller does increase my cruise speed by 8kts.  When set in climb, it extended my take-off distance by 20-30' longer than my sensenich climb prop.  This is the same propellor as originally used by Jon Humberd Super701.
