A new post is up at
RetroMechanix.com reproducing a flight test report on the Grumman F6F-5K Target Drone:
This report covers flight tests of the F6F-5K from May 1946 through April 1947 and discusses the major problems encountered in the adaptation of the basic P-1K automatic pilot installation and related features of the overall drone configuration comprising the system. The report features numerous schematics and photos of the equipment installed in the F6F-5K, as well as photos of the control truck. This is excellent material for modelers who would like to build a super-detailed replica of one of these pilotless Hellcats.
