I've noticed that on some corsair's, they have a rectangular hole manufactured behind the step pad on the right wing.

Any ideas as to why it's there? Was it present on all of the models? Is it to compensate for torgue in any way?
Just curious here http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif

Speed holes... it makes the plane go faster.

But seriously, I'm curious about this as well.

It's a step. When the flaps are lowered the pilot puts his foot in that hole to climb up onto the wing.

Wow! Thanks for the answer. It makes sense.

Still, in a flap? So, it has to be in lowest position in order not to damage it probably.

That hole is a step, it was introduced by Vought on the F4U-4 and Goodyear implemented it in the last of its production runs of the FG-1D. Many -1D's in reserve units received replacement flaps with the step after World War II.

Vought utilized the step to aid in gaining access to the cockpit without having to climb onto the flaps where the outer wing panel meets the inner panel or having to step on the tire and climb onto the wings leading edge. This step also allowed Vought to eliminate the non-skid walking surface on the wing and that added a couple of knots to the Corsair's top speed.

Most restored Corsairs now have the flap with the step.

Sometimes flak makes big holes in my corsair's wings....hilarious to say the least

I beleive the Vought F4U-1D had them as well.

I remember seeing that in the TV show Black Sheep Squadron. Some larger flaps on that.

Negative, Vought introduced the step on their F4U-4, only Goodyear used this design on their last runs of FG-1D's. Goodyear produced FG-1D's well after Vought switched to F4U-4 production. Vought did not produce any F4U-1D's with the step.

I just finished my (my best effort yet) a 1/48 scale Tamiya F4U-1D, you can see by the following link they have it on that one...

Too bad I didn't know, I would have filled it in. (I can always think that mine had a later replacement).

There is a great photo that I have, of a NZ Corsair, F4U-1D, (NZ5201) by John Dibbs, that also clearly shows the hole in the flap. Maybe later F4U-1D's had them! I found this other link to the same aircraft, (different photos, flap still visible...

That or they used F4U-4 flaps during restoration. http://forums.ubi.com/groupee_common/emoticons/icon_biggrin.gif

Those pics are of a Birdcage F4U-1 not a -1D by any manufacturer. Neither that flap, or the cowling are stock for the -1. The F4U-1 cowling had flaps all the way around, but this allowed oil on the windscreen to obscure the pilots view. This problem was corrected in the F4U-1A when Vought omitted a few of the top cowl flaps. That cowling is probably a -1A cowl. The flaps OTOH could be from any later model.

For a good look at an FG-1D restoration, my friend kept great photographic records of the progress to work they were doing to restore a show stopper. www.bentwings.com (http://www.bentwings.com)

Nice looking bird, but I'm getting a little bit annoyed with all these restored 1D Corsairs being painted in 1A colors (like Marine's Dream, which was also incorrectly attributed to Walsh, the one in your link in VF-17 markings. Kepford's bird, isn't it?)

A great number of -1's were modified in the field to seal the cowl flaps at the top of the cowl. As far as I know, the NZ F4U-1 is actually a -1A that was "back dated" during restoration to a -1 configuration. The Planes of Fame Museum has a -1 that was "updated" to -1A configuration and used to have a -1A canopy, but I think it now sports a -1D canopy.

As for painting -1D's to look like -1A's, I think it is because the -1A's had the tricolor paint scheme, far more interesting than overall glossy sea blue, and were involved in the big battles of the Pacific and flown by the top Corsair aces. Unfortunately, so very few -1A's survived the war and assignments to state side training units.

By the time the Corsair was being sold to the scrappers and to civilian aviators, the few remaining -1A's would have been worn out and the vast rows of -1D's would have needed far less work to make them flyable civilian aircraft. Thus ended the -1A from the skies.

Oh, and the National Air and Space Museum has a -1A, but they restored it with the pylons of a -1D, then painted it as a -1A. You would think they would have gotten it right with all their resources.

Update: The Planes of Fame Corsair is an F4U-1A, not an F4U-1 as I previously stated. It has been given a -1D canopy and is now painted as a -1D.
