Description: 1. An aircraft having wings supplied with lateral controls and a fuselage supplied with longitudinal controls, a control arm, means pivotedly suspending said control arm from near the fuselage's roof, means connecting said control arm with the said lateral and longitudinal controls, a pendulum arm, means pivotedly suspending said pendulum arm from the upper part of the control arm and provided to support a weight at its lower end, a dial, an indicator finger, a connecting link member, a locking member secured to the lower portion of said pendulum arm, said connecting link member mounted on the lower part of the control arm and passing through said locking member, said indicator finger secured at the forward end of the connecting link member, said dial located below and adjacent to the indicator finger and secured in a fixed member to the aircraft for the purpose set forth.

2. An aircraft as defined in claim 1 wherein said connecting link member is tubular in shape and houses a rod from said indicator finger, a clamping member on the forward end of said connecting link member holding the rod from said indicator finger in place, whereby when the clamping member is released the indicator finger may be moved forward or backward as the indicator rod is moved in our out of the tubular connecting link member for the purpose set forth.

3. An aircraft as defined in claim 2 wherein said connecting link member is shaped as an arc of a circle with its center at the pivotal bearing part of said pendulum arm, whereby regardless of any change between the said control arm and the pendulum arm the said finger supported by the connecting link member remains the same distance above the said dial.

4. An aircraft having wings supplied with lateral control sand a fuselage supplied with longitudinal controls, a control arm, means pivotedly suspending said control arm from near the roof of the fuselage, means connecting said control arm from near the roof of the fuselage, means connecting said control arm with the said lateral and longitudinal controls, a pendulum arm, means pivotedly suspending said pendulum arm from the upper part of the control arm and secured to the lower part of the pendulum arm in an adjustable manner, a saddle member surrounding the pendulum arm, a weight member supported on the said saddle member, means to slidably raise and lower the said saddle member with the weight member on the pendulum arm, whereby the weight on the saddle may be moved up with the saddle to the top of the pendulum arm at a time when the automatic control feature is not desired and lowered to the lower part of the pendulum arm when the automatic control feature is desired.

5. An aircraft having a fuselage, a narrow shelf member, right and left tiltable wings, a shaft, a pendulum arm provided to support a weight at its lower end, means mounted said shaft with its middle part at the roof of the fuselage, means securing the said pendulum arm to the middle part of said shaft, said narrow shelf member located at the front end of the fuselage with its upper surface as an extension of the fuselage's roof to the front and sideways, said shaft passing out of the fuselage sideways through the narrow shelf member through bearings therein thence into said right and left tiltable wings and rigidly fixed to said tiltable wings, said tiltable wings being intended to lift in flight a small portion of the aircraft's weight and act as front longitudinal controls; whereby when the aircraft in flight the air in the path of the fuselage moves to the right and to the left and on backwards and outwards under the narrow shelf giving an upward thrust to the narrow shelf member from beneath and also increasing the air density under the tiltable wings, at the same time the narrow shelf member prevents the air in its path of the fuselage from turning in its movement to go up over the fuselage's top to reduce the lift by the fuselage.

6. An aircraft having a fuselage of cabin pattern, right and left main wings, narrow shelf member secured to the upper front part of the fuselage and extending out beyond both the front and sides as an extension of the fuselage's roof outward, means mounting a shaft with its middle part at the ceiling of the cabin, said shaft passing out sideways through said narrow shelf member, right and left tiltable wings mounted on the outer ends of said shaft, a dependant arm secured to said shaft and provided to support a weight at it slower end, and means to adjustably fix said pendulum relative to said arm whereby the effect of said pendulum on said tiltable wings may be adjusted and the trim of the aircraft altered.

7. An aircraft fuselage having right and left main wings right and left front tiltable wings located in advance of the aircraft's center of gravity and in advance of the main wings and enveloping and rigidly secured to the outer ends of a shaft, means mounting said shaft at right angles to the longitudinal axis of the fuselage with its middle part close to and beneath the fuselage roof near its forward part, a rear elevator secured pivotedly to the fuselage's most backward part, a depending control arm mounting on said shaft beneath the fuselage roof at its middle part, a pendulum arm journalled at the upper end of the control arm and provided to support a weight at its lower end, means adjustably securing said pendulum arm to said control arm, means to connect the control arm with said rear elevator; whereby said tiltable wings in front of the aircraft's center of gravity, and a weight secured to the pendulum arm acts in flight as the influence that tends automatically to control the aircraft in longitudinal balance by both the tiltable wings and the rear elevator.

8. An aircraft having wings and fuselage ports, an elevator at the rear end of said fuselage, said fuselage being of inclosed cabin pattern, a control arm suspended pivotedly from near the roof of the cabin, a pendulum arm suspended pivotedly from the upper part of the control arm and a weight at its lower end, a connecting link member, a handle and a locking member secured to the lower portion of said pendulum arm, said connecting link member mounted on the lower part of the control arm and passing through the said locking member, a handle secured to the lower portion of said control arm, a pilot's seat located within the cabin in a fixed position adjacent to the arms, means connecting said control arm with said elevator; whereby when the aircraft is moving on the ground or on the water or in the air the pilot may as the need arises take hold by one hand of the handle which is secured to the control arm and with his other hand release the locking member and then move the pendulum arm in its new position and both hands may be removed, and a weight on the lower part of the pendulum arm acting as the influence to automatically control the aircraft longitudinally.

9. An aircraft having wings with ailerons and fuselage of inclosed cabin pattern, an elevator at the rear end of the fuselage, a control arm suspended pivotedly beneath the roof of the cabin, a pendulum arm suspended pivotedly from the upper part of the control arm the same being provided to support a weight at its lower part, a handle and a locking member secured to the lower portion of the pendulum arm, a connecting link member secured to the lower portion of the pendulum arm, a connecting link member attached to the lower part of the control arm and passing through the said locking member, a handle secured to the lower portion of said control arm, a pilot's seat located within the cabin in a fixed position adjacent to the pendulum arm and the control arm, means connecting said control arm with said ailerons and means connecting said control arm with said elevator; whereby when the aircraft is in flight the pilot may as the need arises take hold of the control arm and move the two arms sideways thereby moving the ailerons for lateral control, and for changing the angle of attack of the wings the pilot holds the control arm's handle by one hand while his other hand holds the handle on the pendulum arm unlocking the locking member and then moves the pendulum arm into a new position on the connecting link and then relocks the arms together, and both hands may be removed from the handles to let the weight do the work by itself automatically.

10. An aircraft having wings and fuselage parts, an elevator at the rear end of the fuselage, a control arm suspended pivotedly from a fixed part of fuselage, a pendulum arm suspended from the upper part of the control arm the same being provided to support a weight at its lower part, a control rod, a forked bearing connecting to support the control rod with the control arm, means connecting the rear end of said control rod to the rear elevator, a guide means for said control rod mounted on the structure part of the aircraft's and adjustable motion limiting members mounted on said control rod at each said guide means whereby back and forth movement of said control and pendulum arms are limited.

11. An aircraft having wings with ailerons and fuselage parts, an elevator at the rear end of the fuselage, a control arm suspended pivotedly from a fixed part of the fuselage, a pendulum arm suspended pivotedly from the upper part of the control arm the same being provided to support a weight at its lower part, a control rod and cables, a forked bearing connecting the control rod with the control arm, means for adjusting the said forked bearing up or down along the said control arm, means connecting the rear end of said control rod to the rear elevator, means connecting said cables to the control rod at one of their ends and means connecting said cables to the ailerons at their other ends; whereby when the control arm is moved forward or backward by hand or by gravity influence the control rod also moves forward or backward thereby turning the rear elevator for longitudinal control, and whereby when the control arm is moved by hand or by gravity influence from one side to the other side a twist movement occurs of the control rod which turns the means at the control and in turn moves the cables that turns the ailerons for lateral control.

12. An aircraft having wing and fuselage parts, longitudinal and lateral control members, a control arm suspended pivotedly from a fixed part of the aircraft, a pendulum arm suspended pivotedly from the upper part of the control arm and provided to support a weight on its lower part, means joining the control arm with the pendulum arm at their lower parts, an indicator finger mounted on the said means that joins the said arms, a dial secured to a fixed part of the aircraft beneath and adjacent the indicator's finger, and means connecting the said control arm to said longitudinal and lateral control members; whereby when the aircraft is in flight the location of the indicator finger over the dial will indicate to the pilot the balanced or unbalanced position of the aircraft.

13. An aircraft having a fuselage of cabin pattern, right and left main wings, right and left tiltable wings, narrow shelf member secured to the upper front part of the fuselage and extends out beyond the sides as an extension of the fuselage's roof, a pendulum arm with a weight on its lower part is pivotedly supported to the upper part of a control arm, the two arms are adjustably secured together at their lower parts, a shaft with its middle part within the fuselage cabin next to the ceiling and passing out sideways through said narrow shelf member into said tiltable wings and rigidly secured thereto, said control arm is secured to the middle part of the shaft to turn the shaft clockwise and anti-clockwise and thus the tiltable wings angle of attack is altered and its lift influence varied thereby controlling the aircraft longitudinally by the influence of said weight.

14. An aircraft having a fuselage, wings, control arm, pendulum arm, a source of power, air propeller driven by said source of power, an air draining system consisting of an air outlet port and an air duct located beneath the roof of the fuselage and air entrance ports in the roof of the fuselage spaced for and aft, the fore entrance port placed in front of the aircraft's center of gravity, said air duct having an air valve to vary the flow of air entering the fore and aft entrance ports, said air outlet located at the front and lower part of the sweep of the propeller, said propeller located at the extreme rear of the fuselage, the upper portion of the sweep of the propeller blades being above the rear end of the roof, means pivotally suspending said control arm from near the fuselage's roof, means pivotally suspending said pendulum arm from the upper part of the control arm provided for a weight on its lower part, adjustable connecting means between the control arm and pendulum arm, connecting means between the said control arm and the sad air valve, whereby when the source of power is applied to rotate the propeller acts as a suction fan to draw air out at the air outlet port thereby causing an air flow at the top surface of the fuselage into the fore and aft entrance ports effecting a lift influence to the fuselage in front of the aircraft's center of gravity, at the same time a suction takes place above the rear end of the fuselage giving a lift influence back of the aircraft's center of gravity, the position of the control arm controls the position of the air valve which in turn controls the portion of air entering the fore and aft air inlet ports thus the pendulum arm through the control arm controls the aircraft longitudinally by controlling the location of the lift influence without reducing the total lift influence.

15. An aircraft having a fuselage, right and left wings, a control arm, a pendulum arm, a source of power, right and left air propellers driven by said source of power, an air drainage system consisting of air outlet ports and air inlet ports with the outlet ports, said inlet ports are located in the wing top surfaces, said outlet ports are located back of said propellers, means pivotally suspending said control arm from near the fuselage's roof, means pivotally suspending said pendulum arm from the upper part of the control arm and provided for a weight on its lower part, adjustable connecting means between the control arm and the pendulum arm, connecting means between the control arm and air valves placed within the said air ducts, whereby when the source of power is applied to the propellers forward thrusts are in effect a lift influence to the wings, the position of the control and pendulum arms controls the position of the air valves which in turn controls the operation of air entering the right wing inlet ports compared to the air entering the left wing inlet ports, thus the weight on the pendulum arm through the control arm controls the aircraft laterally.
