The Fletcher FBT-2 was a military trainer aircraft built in the United States in the early 1940s. Although it was never used in its intended role, it played a small part in the development of guided bombs. The FBT-2 was a low-wing cantilever monoplane with fixed tailwheel undercarriage which seated the pilot and instructor in tandem in an enclosed cockpit. Construction throughout was of plywood, and the wings were interchangeable, as were the tail panels. A single prototype was evaluated for military use, but generated no interest. However, the USAAF ordered the type as a radio-controlled target drone under the designation XPQ-11. The prototype FBT-2 was modified to use as a drone controller as the YCQ-1A. Two batches of 50 drones were ordered, but before any were delivered, the type was cancelled in favour of the PQ-8 Cadet. The Army then ordered the PQ-11s under construction to be completed without engines so that bombs could be fitted in their noses to use for glide bomb experiments as the BG-1. No further examples were ordered past this initial batch of ten.
