Abstract

Claims (58)

1. A wing assembly for a model airplane, the wing assembly comprising:

first and second wing segments removably coupleable to respective side wing attachment regions of a fuselage of the model airplane;

a wing rib removably disposable at a top portion of the fuselage, the wing rib including upper wing attachment regions to which respective ones of the wing segments may be removably and alternatively coupled when the wing segments are decoupled from the side wing attachment regions of the fuselage;

wherein the wing rib is attached to an upper portion of a wing supporting canopy structure removably coupleable to the fuselage of the model airplane; and

an alternative canopy structure lacking a wing rib, the alternative canopy structure being coupleable to the fuselage when the wing supporting canopy structure is decoupled from the fuselage and the wing segments are coupled to the side wing attachment regions of the fuselage.

2. The wing assembly of claim 1 , wherein the wing rib is removably coupleable to the fuselage such that the wing rib is decoupleable from the fuselage when the wing segments are coupled to the side wing attachment regions of the fuselage.

3. A wing assembly for a model airplane, the wing assembly comprising:

first and second wing segments removably coupleable to respective side wing attachment regions of a fuselage of the model airplane;

a wing rib removably disposable at a top portion of the fuselage, the wing rib including upper wing attachment regions to which respective ones of the wing segments may be removably and alternatively coupled when the wing segments are decoupled from the side wing attachment regions of the fuselage;

a first end of the first wing segment has a first surface profile substantially corresponding to a second surface profile of a first of the side wing attachment regions; and

a first of the upper wing attachment regions of the wing rib has a third surface profile substantially matching the second surface profile.

4. The wing assembly of claim 3 , wherein the first wing segment includes an opening having an open end at the first end of the first wing segment and a hollow interior, and

the wing assembly further comprises a connecting member having a first end removably insertable into the opening of the first wing segment, the connecting member being coupleable to the fuselage of the model airplane.

5. The wing assembly of claim 4 , wherein the connecting member is alternatively removably coupleable to the fuselage at the first of the side wing attachment regions and the first of the upper wing attachment regions.

6. A wing assembly for a model airplane, the wing assembly comprising:

first and second wing segments removably coupleable to respective side wing attachment regions of a fuselage of the model airplane;

a wing rib removably disposable at a top portion of the fuselage, the wing rib including upper wing attachment regions to which respective ones of the wing segments may be removably and alternatively coupled when the wing segments are decoupled from the side wing attachment regions of the fuselage;

a connecting member having a first end removably insertable into an opening of the first wing segment, the connecting member removably coupleable to the fuselage;

wherein the connecting member has a second end removably insertable into a second opening of the second wing segment, the connecting member removably passable through the fuselage;

a first ferromagnetic material disposed at the first end of the connecting member;

a second ferromagnetic material disposed within the first wing segment at an interior end of the opening;

wherein the first ferromagnetic material and the second ferromagnetic material are magnetically attracted to one another;

a third ferromagnetic material disposed at the second end of the connecting member; and

a fourth ferromagnetic material disposed within the second wing segment at an interior end of the second opening;

wherein the third ferromagnetic material and the fourth ferromagnetic material are magnetically attracted to one another.

7. The wing assembly of claim 6 , further comprising:

a first canopy including the wing rib, the first canopy being removably attacheable to the fuselage for use in alternatively coupling the wing segments to the wing rib; and

a second canopy removably attacheable to the fuselage when the wing segments are coupled to the side wing attachment regions.

8. A model airplane comprising:

first and second wing segments;

a fuselage having first and second side wing attachment regions on opposite sides of the fuselage;

a wing support canopy including a wing rib having first and second upper wing attachment regions on opposite sides of the wing rib, the wing support canopy selectively attacheable to the fuselage; and

an alternative canopy lacking a wing rib, the alternative canopy selectively attacheable to the fuselage,

wherein the wing segments may be selectively coupled to respective ones of the side wing attachment regions and to respective ones of the upper wing attachment regions, and the alternative canopy may be coupled to the fuselage instead of the wing support canopy when the wing segments are coupled to the side wing attachment regions.

9. The model airplane of claim 8 , wherein

a first end of the first wing segment has a first surface profile substantially corresponding to a second surface profile of the first side wing attachment region, and

the first upper wing attachment region has a third surface profile substantially matching the second surface profile.

10. The model airplane of claim 9 , wherein

the first wing segment includes an opening having an open end at the first end of the first wing segment and a hollow interior, and

the model airplane further comprises a connecting member having a first end insertable into the opening of the first wing segment, the connecting member being coupleable to the fuselage of the model airplane.

11. The model airplane of claim 8 , further comprising:

a connecting member having a first end insertable into an opening of the first wing segment, the connecting member being coupled to the fuselage of the model airplane;

a first ferromagnetic material disposed at the first end of the connecting member; and

a second ferromagnetic material disposed within the first wing segment at an interior end of the opening;

wherein the first ferromagnetic material and the second ferromagnetic material are magnetically attracted to one another.

12. A model airplane fuselage comprising:

first and second side wing attachment regions on opposite sides of the fuselage;

a wing support canopy including a wing rib having first and second upper wing attachment regions on opposite sides of the wing rib, the wing support canopy selectively attacheable to the fuselage; and

an alternative canopy lacking a wing rib, the alternative canopy attacheable to the fuselage,

wherein first and second wing segments may be selectively coupled to respective ones of the side wing attachment regions and to respective ones of the upper wing attachment regions, and the alternative canopy may be coupled to the fuselage instead of the wing support canopy when the wing segments are coupled to the side wing attachment regions.

13. The model airplane fuselage of claim 12 , wherein

the first side wing attachment region has a first surface profile substantially corresponding to a second surface profile of an end of the first wing segment, and
