Abstract

A radio controlled model rotorcraft implemented with features improving ease of flight and flight performance by increasing structural stability, increasing rotorcraft visibility and orientation awareness through the use of multifunctioning, configurable, and aesthetically pleasing components, while also increasing resistance to damage from crashes through use of impact and vibration absorbing components.

First claim

The invention claimed is:

1. A radio controlled model rotorcraft having an electronics compartment, the model rotorcraft comprising:
a circuit board;
at least one light source electrically coupled to the circuit board; and
a housing, the housing comprising:
a first frame;
a second frame removably coupled to the first frame; and
one or more housing inner surfaces;

wherein the circuit board is mounted to the first frame and the second frame by the at least one light source;
wherein the circuit board is disposed within the housing spaced apart from each housing inner surface; and
at least one rotor assembly, the at least one rotor assembly comprising at least one arm extending from the housing and at least one rotorcraft component.

2. The model rotorcraft of claim 1 , further comprising:
the first frame comprising at least one first recess, the at least one first recess receiving the at least one light source; and
wherein the circuit board is mounted to the first frame and the second frame by the at least one light source received within the at least first recess.

3. The model rotorcraft of claim 2 , further comprising at least one locator member coupled to the at least one light source.

4. The model rotorcraft of claim 3 , wherein the at least one locator member coupled to the at least one light source comprises an elastically deformable material.

5. The model rotorcraft of claim 4 , wherein the at least one locator member coupled to the at least one light source is configured to at least partially absorb vibration caused by operation of the at least one rotorcraft component of the at least one rotor assembly.

6. The model rotorcraft of claim 4 , wherein the at least one locator member coupled to the at least one light source comprises a continuous loop of material.

7. The model rotorcraft of claim 2 , the second frame further comprising at least one second recess, the at least one second recess cooperating with the at least one first recess to receive and secure the at least one light source.

8. The model rotorcraft of claim 7 , wherein the position of the at least one light source received within the at least one first recess and the at least one second recess is fixed by the respective first and second recesses against movement in at least three orthogonal directions.

9. The model rotorcraft of claim 2 , wherein the at least one light source received by the at least one first recess is secured against movement in at least one direction.

10. The model rotorcraft of claim 1 , the housing further comprising at least one opening passing outwardly through at least one of the one or more inner surfaces of the housing, wherein the at least one opening is optically paired with, and receives light most intensely from, the at least one light source.

11. The model rotorcraft of claim 1 , wherein the circuit board is mounted within the housing solely by a plurality of the light sources.

12. A radio controlled model rotorcraft, comprising:
a circuit board;
at least one first light source electrically coupled to the circuit board; and
a housing, comprising:
a first frame, at least a portion of the first frame comprising at least one first light securing surface;
a second frame coupled to the first frame; and
wherein the at least one first light securing surface secures at least a portion of the at least one first light source between the coupled first and second frames;

wherein the circuit board is mounted to the first frame by the at least one first light source secured by the at least one first light securing surface; and
at least one rotor assembly comprising an arm, the arm further comprising at least one light transmitting channel extending from the housing, the at least one light transmitting channel configured to allow light from the at least one first light source to be emitted beyond the housing and into the at least one light transmitting channel.

13. The model rotorcraft of claim 12 , wherein at least a portion of the at least one first light source is disposed within at least a portion of the at least one light transmitting channel.

14. The model rotorcraft of claim 12 , wherein the light transmitting channel comprises light conducting material, and wherein the light transmitting channel forms at least a portion of a socket, the socket receiving at least a portion of the at least one first light source and transmitting at least a portion of light emitted from the at least one first light source into the light transmitting channel.

15. The model rotorcraft of claim 12 , wherein at least a portion of the second frame comprises at least one second light securing surface; and
wherein the at least one second light securing surface secures at least a portion of the at least one first light source between the coupled first and second frames.

16. The model rotorcraft of claim 15 , wherein the position of the first light source is fixed in at least three orthogonal directions.

17. The model rotorcraft of claim 12 , further comprising at least one locator member coupled to the at least one first light source, the at least one first light source at least partially received by the first frame.

18. The model rotorcraft of claim 17 , wherein the at least one locator member comprises an elastically deformable material.

19. The model rotorcraft of claim 17 , wherein the at least one locator member is configured to at least partially isolate the circuit board from vibration caused by operation of rotorcraft components spaced apart from the circuit board.

20. The model rotorcraft of claim 17 , wherein the at least one locator member comprises a continuous loop of material and is disposed around the at least one first light source.

21. A compartment for receiving an electronic component of a radio controlled model rotorcraft, comprising:
a first frame
a circuit board;
at least one light source electrically coupled to the circuit board;
wherein the first frame receives and at least partially encloses the at least one light source;
wherein the circuit board is mounted within the first frame by the at least one light source;
wherein the circuit board is disposed within the first frame spaced apart from the inner surfaces of the first frame; and
wherein the first frame comprises at least one opening passing outwardly through a surface of the first frame, the at least one opening optically paired with, and receiving light from the at least one light source.

22. The compartment of claim 21 , wherein the first frame comprises at least one first recess, the at least one first recess receiving the at least one light source.

23. The compartment of claim 22 , wherein the at least one light source received by the first recess is secured against movement in at least one direction.

24. The compartment of claim 23 , further comprising at least one locator member coupled to the at least one light source received within the at least one first recess.

25. The compartment of claim 24 , wherein the at least one locator member comprises a loop of an elastically deformable material, configured to snugly fit around the at least one light source.
