Both wings simultaneous... https://www.youtube.com/watch?v=FQxb-V-rZqA&ytbChannel=null One wing at a time ... https://www.youtube.com/watch?v=-vvbF7IumME FYI, according to cockpit pictures, the USN Corsairs had a single lever that was marked "Spread-Neutral-Fold" next to it was a lockout lever so it wasn't accidentally tripped. What you are seeing in the second video is probably a tired hydraulic pump or possibly air trapped in the system. As you see, both wings start to spread, but when the left wing tips over and starts to drop, the weight of the wing pulls on the hydraulic cylinder, causing a temporary pull, resulting in a drop in pressure, which made the right wing stop moving. As soon as the pump caught up, the right wing started moving down again. Its feasible that in the neutral position, the locks can be disengaged and manually fold the wing. Its also possible that the Royal Navy asked for separate L/R levers. JeepsGunsTanks 1 Link to comment Share on other sites More sharing options...
Finn Posted January 10, 2019 Share Posted January 10, 2019 A couple more pics of #313, still one up: both wings down: Jari LSP_K2 1 Link to comment Share on other sites More sharing options...
red Dog Posted January 10, 2019 Share Posted January 10, 2019 When I researched the same question when doing this one i found out that it was indeed possible, but both small doors at mid section should be up, not only the one with the raised wing. Like in this picture, clearly seen on the starboard wing in red Link to comment Share on other sites More sharing options...
LSP_Ron Posted January 10, 2019 Share Posted January 10, 2019 Those are the wing lock indicator doors. The wing is locked when closed. Link to comment Share on other sites More sharing options...
Finn Posted January 11, 2019 Share Posted January 11, 2019 On pg32 (reader) of this manual it tells you how to fold one wing: http://www.avialogs.com/index.php/aircraft/usa/vought/f4ucorsair/an-01-45hb-1-pilot-s-handbook-for-f4u-4-airplane.html Jari Link to comment Share on other sites More sharing options...

I just posted the videos to show that depending on when a snapshot was taken (like the one of 313) it's possible to see one wing down while the other was still up (as part of the normal process).
