The KR030 Topaz is a high-wing cantilevered monoplane. All major components of the aircraft are constructed of glass and carbon fiber composites.
The fuselage consists of a self-supporting shell structure made from carbon fiber PARABEAM material. In the forward section of the fuselage is the two side-by-side seats. The cabin is a very comfortable 47" wide. The hull consists of two symmetrical halves fused togehter. The integrated floor also includes the form for the seats built into the structure. The seats are made of composite materials with optional leather. The split windshield is made of UV-resistant polycarbonate.
The landing gear is tricycle configuration with composit main gear, hydraulic brakes, and a steerable nose wheel coupled to the rudder.
The wing contains the electric flaps and ailerons that are operated by push rod linkage. The flaps and ailerons are made of carbon fiber composite for extremely high stiffness with minimal mass (anti-flutter requirements). The wing has no control systems or other components installed inside.
The Controls are pushrod type and the elevator includes electric trim tabs controlled from the control stick. The control stick is mounted in the center console. This allows plenty of room for writing and maps on the lap of the pilot and copilot. It's also out of the way for entry and exit of the aricraft. The aircraft is equiped with a ROTAX 912 UL 80 Hp engine standard with a 100hp option. The 22gal fuel tank is wing mounted or optionally can bemounted behind the passenger seat.
