King Katmai - For Those Who Walk A Path Less Traveled

Specifications

"I am more convinced than ever that if one is in the field of building back country airplanes, it is essential to take the bird into the most difficult strips. It is not only a process of identifying necessary enhancements, it also clearly demonstrates the airplane is capable of doing the job."

High Lift Canard

Improved Maneuverability

The King Katmai's nose mounted Canard minimizes the chance of damaging the nose wheel.

Katmai High Lift Canard

The Katmai's unique nose-mounted canard has a functioning elevator that is integrated with the flight control system.

This provides additional lift, reduces the down-load on the tail, increases empennage elevator effectiveness at slow speeds, reduces the stall speed and improves the stall resistance.

This not only reduces the take off and landing distances, but it provides a safe, flat altitude at slow speeds to increase safety, handling and forward visibility.

During taxi, take-off and landing rollout, the canard also reduces much of the weight supported by the nose wheel weight allowing the airplane to be operated from areas too rough for other tri-geared airplanes.

In an engine out emergency, the canard permits lower touch down speeds which drastically reduce impact forces.

All routine engine maintenance can be done without removing the canard. If removal is required for major engine work, the canard structure is designed so it can be quickly removed and reinstalled.

Katmai Aerodynamic Efficiency

The Katmai’s advanced aerodynamics provide additional lift for those ultra-short back country sites.

On take off the airplane transitions into a safe flat altitude at 45 knots signaling the Katmai is now ahead of the power curve.

At this point steep turns may be made safely. An engine failure on take off does not present a hazard, and an emergency landing may be made safely.

Powerplant

Increased Power

The Katmai uses a factory Continental IO-550 engine with an 82 inch, three-blade propeller (an 86 inch propeller is optional).

Katmai Powerplant

The Katmai uses a factory Continental IO-550 engine with an 82 inch, three-blade propeller (an 86 inch propeller is optional).

This 300 HP engine has no time limit at full power, is quiet on take off, very fuel efficient when operated LOP and eliminates the issue of carburetor ice thanks to fuel injection.

This engine decreases the take off roll, increases the ROC, service ceiling and speed. All engines come with a full factory warranty.

Landing Gear

Interchangeable Options

The Katmai provides a wide variety of easily interchangeable landing gear options.

Katmai Landing Gear

The Katmai provides a wide variety of easily interchangeable landing gear options.

The gear legs have anti-abrasion Stainless Steel leading edges.

The brake lines are protected from damage by the landing gear leg and heavy duty brakes are utilized. Shown here are the 29 inch Alaskan Bushwheels with an 8.50x6 nose wheel.
