Does anyone have information on the current whereabouts of the second XF-11 prototype? The wikipedia articles for two other famous Hughes aircraft, the Hercules (Spruce Goose) and the H-1 Racer, include present-day location (museum) locations. The location of the second XF-11 prototype, if it survives, might make a nice addition to the page. Strawtarget (talk) 20:56, 13 December 2007 (UTC)
From the entry: Hughes did not follow the agreed testing program and communications protocol, and remained airborne almost twice as long as planned. An hour into the flight (after on-board recording cameras had run out of film), a leak caused the right-hand propeller controls to lose their effectiveness....
What does "effectiveness" mean in this case? They stopped working? They didn't work as well as they had previously? Could a better word be substituted for the entry
- I would take it to mean the prop-pitch controls stopped working. A hydraulic system (such as was used for prop-pitch control) doesn't work if it has no fluid. A better wording might be: "... caused the right-hand propeller controls to become ineffective...." FWIW. Jororo05 (talk) 22:15, 27 June 2015 (UTC)
