I thought inflatable wing can be an option. You can squezee 50 deflated boomerang in to small package and inflate them whereever you would use your boomerang.

American army tried inflatable UAV wings once and success.

You can inflate with a plastic liquid or if you have a giant man size world record big moomerang , you can inflate with air.

Here are few ideas and papers :

AIAA Infotech@Aerospace, September 26-29, 2005 Washington, DC

Inflatable and Warpable Wings for Meso-scale UAVs

Andrew Simpson, Jamey Jacob†,
and Suzanne Smith‡
Mechanical Engineering Dept.
University of Kentucky, Lexington, KY

The paper presents work on testing of inflatable wings for unmanned aerial vehicles (UAVs). Design and construction of inflatable wings is discussed, along with ground and flight testing. Predictions and correlations of the forces required to warp (twist) the wings to a particular shape and the aerodynamic forces generated by that shape change are presented. The focus is on characterizing the deformation of the wings and development
of a system to deform the wings inflight. Relations between wing stiffness and internal pressure and the impact of external loads are presented. Mechanical manipulation of the wing shape on a test vehicle is shown to be an effective means of roll control. Finally, damage resistance is shown from results of flight tests.

An inflatable wing using the principle of Tensairity

[Abstract] The paper describes the new concept Tensairity which can be used
to significantly improve the load bearing capacity of inflatable wings. The basic principle of Tensairity is to use an inflatable structure to stabilize conventional compression and tension elements. So far, Tensairity has been mainly used in civil engineering application like roof structures and bridges. In this work, considerations to apply Tensairity to wing structures
are given and the construction of two wing-like Tensairity kite prototypes is described. Test results on the Tensairity structure used in these kites are presented and compared to purely air inflated structures. Finally, the advantages of Tensairity wings are discussed and some application areas of these wings are suggested.

Its pretty interesting topic! I was searching about it but now I don't need to know more about the plane because you define its parts and structure in detail.
