The main landing gear is hydraulic operated and retracts 90° inward to the line of flight. The tail wheel is fully retractable, but is non-lockable and non-steerable. It is held straight in the extended position by two shock chords.
Wing flaps are small but adequate. They are also hydraulically operated.
Engine cowl flaps and oil cooler flaps are manually operated.
The ailerons are very large and somewhat resemble the Fries Type.
The plane is powered with a fourteen (14) cylinder twin row radical air cooled engine estimated at 900 H. P. at sixteen thousand (16,000) feet. Three (3) non-self-sealing gasoline tanks are provided. Two (2) wing tanks of fifty-four (54) gallons each and one (1) fuselage tank of thirty-seven (37) gallons capacity. The engine is equipped with a single stage blower and some method is employed for manifold pressure regulation, but the exact details of the system are unknown at the present time. It is equipped with a three (3) blade hydraulic constant speed propeller. Engine is equipped with a float type low pressure carbureter.
Weight of the airplane with a full military load—5555 pounds.
5. COCKPIT:
All around visibility from the cockpit is excellent. The only restriction is in a narrow turn-over brace directly behind the pilot's head.
All flight controls are conventional. A rudder bar is used instead of individual pedals. Toe brakes are used and are hydraulically operated.
All flight and engine controls are conveniently placed around the cockpit within easy reach of the pilot. The pilot sitting normally in the cockpit can reach every control necessary to operate the airplane and fire the guns.
6. FLYING CHARACTERISTICS:
The large ailerons make the ship highly maneuverable at speeds up to three hundred (300) miles per hour indicated. Above three hundred (300) miles per hour indicated, it is virtually impossible to reverse a turn.
