Mounting the panel model on a short strut has the advantage of decreasing the tare drag of the setup.
把翼段模型安装在一个短支柱上，其优点是减少了安装支架的阻力。
Balance weights, if required, shall be secured to the rotor resistance ring or rotor fins.
如果需要的话，应该配置平衡重装置以保护定子阻力环或定子翼。
A next-generation combat drone, for example, might loiter for hours above a potential target on elongated, low-drag wings.
