The invention provides a telescopic device for a tail pipe of an aeromodelling helicopter. The tail pipe device comprises a front pipe, a rear pipe, a double-locking mechanism, an empennage and a tail rotor mechanism. And shortening the tail pipe: releasing the locking of the double-locking mechanism, and pushing the rear pipe into the front pipe to achieve the purpose of shortening the tail pipe. The rear pipe is pulled to a proper position, the front pipe and the rear pipe are stably connected through the locking function of the double locking mechanisms, and the purpose of extending the tail pipe is achieved. In the extension state, the front pipe and the rear pipe are stably connected through the double-locking mechanism, and the stability of the model airplane helicopter during flight is guaranteed; cost is low and realization is easy.

    本发明提供一种航模直升机尾管伸缩装置。所述尾管装置包括:前管,后管,双锁止机构,尾翼,尾桨机构。缩短尾管步骤:解除双锁止机构的锁止,将后管推入前管,达成缩短尾管的目的。伸长尾管步骤:将后管拉到适当位置,利用双锁止机构的锁止功能,使前管和后管稳固连接,达成伸长尾管的目的。在伸长状态下,利用双锁止机构使前管和后管稳固连接,保证航模直升机飞行时的稳定性;成本较低,易于实现。
