BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to an improved model helicopter, and more particularly to an improved model helicopter having an easily detachable tail pipe connecting base. [0003] 2. Description of the Related Art [0004] Referring to FIG. 7 for the helicopter casing structure of a prior art model helicopter, the structure includes two corresponding casings 7 engaged with each other, and the two casings 7 are engaged with each other by a plurality of screws 8, and the two casings 7 include a rotor transmission mechanism (not shown in the figure) of the model helicopter, a servo base 9, a control cantilever 91, an elevation control base 92 (since the two casings includes many components that are not related to the present invention, therefore only the related components are shown in the figure for illustrations), and the two casings separately include pivotal bases 71 that can be engaged with each other and pivotally connected to a tail rotor transmission module 93. [0005] However, the tail rotor transmission module 93 will be damaged easily, if the model helicopter is fallen down accidentally. If a user wants to repair the tail rotor transmission module 93, it is necessary to remove the two casings 7 first and then loosen the plurality of secured screws 8 one by one before the user can repair or replace the tail rotor transmission module 93. Such arrangement causes inconvenience to the user. Furthermore, the user has to reinstall the two casings 7 and secure the screws back to their original positions after the repair is made, and thus the design causes tremendous inconvenience and waste time for the maintenance and repair. SUMMARY OF THE INVENTION [0006] The primary objective of the present invention is to overcome the aforementioned shortcomings by providing an improved model helicopter, wherein a main body for containing a rotor transmission mechanism of the model helicopter and a tail pipe connecting base are detachably connected with each other, such that if the tail rotor transmission module installed at the tail pipe connecting base is damaged, users can remove the tail pipe connecting base directly to facilitate the maintenance, repair, or replacement of the tail rotor transmission module. [0007] To achieve the foregoing objective, the improved model helicopter of the invention comprises: [0008] a main body, having a containing space for installing a rotor transmission mechanism of a model helicopter, and a connecting track transversally disposed at the main body; [0009] a tail pipe connecting base, having a positioning groove for connecting a tail pipe of the model helicopter, a pivotal base disposed at an end without the positioning groove, and at least one pressing surface pressing against the connecting track of the main body and detachably connecting the connecting track of the main body to produce a relative pivotal rotation between the tail pipe connecting base and the main body; and [0010] a transmission module, pivotally coupled to the pivotal base of the tail pipe connecting base, and having a first transmission portion disposed at an end of the transmission module and linked with the rotor transmission mechanism, and another end of the transmission module having a second transmission portion. BRIEF DESCRIPTION OF THE DRAWINGS [0011] FIG. 1 is a perspective view of a model helicopter adopting a tail pipe connecting base according to the present invention; [0012] FIG. 2 is a perspective view of a tail pipe connecting base connected with a tail pipe according to the present invention; [0013] FIG. 3 is a schematic view of a tail pipe connecting base according to the present invention; [0014] FIG. 4 is an exploded view of a main body according to the present invention; [0015] FIG. 5 is a schematic view of the structure of a tail pipe connecting base according to the present invention; [0016] FIG. 6 is a schematic view of the structure of a tail pipe connecting base connected with a tail pipe according to the present invention; and [0017] FIG. 7 is an exploded view of a casing of a prior art model helicopter. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS [0018] Referring to FIGS. 1 to 6, the structure according to a preferred embodiment of the present invention is used for illustrations only, but not intended to limit the scope of the present invention. [0019] In FIG. 1, a perspective view of a model helicopter adopting a tail pipe connecting base according to the present invention is shown, and the structure of the model helicopter includes a main body 1, a rotor transmission mechanism 2, a rotor 3, a tail pipe connecting base 4, and a tail pipe 5. [0020] Referring to FIGS. 1 to 3, the main body 1 of the embodiment is formed integrally, and the main body 1 has a containing space 11 for installing the rotor transmission mechanism 2 of the model helicopter and a containing track 12 transversally disposed on the main body 1. It is worth pointing out that the main body 1 could be made by engaging two side panels. Continue reading about Model helicopter...
