这 无线电飞机 BTT该公司称为RP-71，美国海军称为WS-426/2，美国空军称为WS-462/2，是一系列由无线电飞机公司（后来是诺斯罗普的一个部门）生产的目标无人机。

MQM-57 法尔科纳: A variant of the BTT designated the RP-71, also known as the SD-1 Observer and later redesignated MQM-57 Falconer, was built for battlefield reconnaissance, with first flight in 1955. The Falconer was similar in appearance to the Shelduck, but had a slightly longer and stockier fuselage. It had an autopilot system with radio-control backup, and could carry cameras, as well as illumination flares for night reconnaissance. Equipment was loaded through a hump in the back between the wings. Although it only had an endurance of a little more than a half-hour, making it of limited use, about 1,500 Falconers were built and the type was used internationally with several different military forces, remaining in service into the 1970s. Over 73,000 BTT targets were built in all, and the type was used by at least 18 nations. Some may still be lingering in service.

文本 无线电飞机 BTT 是 Radioplane Company 在 1950 年代和 1960 年代开发的一系列目标无人机。BTT 代表基本训练目标，表明它打算用作训练高射炮手和导弹作员的低成本和简单的空中目标。BTT 无人机由驱动推进螺旋桨的二冲程活塞发动机提供动力，并有一个带有双臂尾翼的木制机身。
BTT 无人机可以从弹射器或零长度发射器发射，并通过降落伞回收。BTT 无人机被美国空军、海军和陆军以及几个外国广泛使用。BTT 无人机还被改装用于各种实验目的，例如测试雷达系统、电子对抗措施和空对空导弹。BTT 无人机最终在 1970 年代和 1980 年代被更先进的目标无人机所取代。
