Are there any game-related differences between the F4U-1D and F4U-1D_CW?

[tigershark1-1]

I've been wondering about this. While the visual differences are immediately apparent, are there any differences in the in-game flight models? And what might those differences be? I've heard that the UK Corsair saw improved roll rate due to its clipped wingtips – is this also reproduced in DCSF4U?

The tests that the FAA performed, found that the rollrate is negligible compared to the standard US wing rollrate.

There's anecdotal claims the clipped wing Corsairs had a faster sink rate during landing, but AFAIK there's no actual flight tests that confirm this.

Is the flight model the same?

Yes

I'd be surprised if the small change to the wingtip profile made any meaningful difference to performance in real life. Maybe with very careful testing they might have been able to detect a difference, but why would they bother? It needed to be done (to fit some RN carriers), so they did it. Pilots who expected a difference might have thought there was one, but given all the other variables, there's no particular reason to assume this was more than imagination. And even if there was a difference, we don't have data on it...

Were wings not clipped to improve low-altitude performance? That’s why the Spitfire’s wings were clipped in some variants, I believe…

I believe they were clipped to fit into the slightly smaller British carriers.

Yup. Sources say by 8 inches - not sure if that's per tip, or overall. Either way, it was because some RN carriers had hangers which were just too low to take an unclipped Corsair with wings folded. 

There are a lot of myths floating around with regard to RN Corsairs, and the idea that this minor modification was made for any more significant reason is one of them. The RN also operated land-based Corsairs, unclipped, so they clearly didn't think it mattered otherwise.

It was too low for Corsairs because the armoured deck, which was 4 inches thick, produced a lot of top weight, so it had to be as low as possible to maintain stability.

This created a hangar much reduced in height from a US carrier.

Luckily the wing tips could be removed. History might have been very different otherwise.

Those clipped-wing Spits (and the A6M3 Model 32) were clipped CONSIDERABLY more than the Corsair's.

I think it was to improve roll-rate. I can't think of any other flight dynamics benefit. The induced drag is smaller with rounded wingtips if I'm not mistaken (that's why the spit has them in the first place I guess).

But I might be completely mistaken - that's out of my league to be honest.

Correct, the clipped wings were to improve roll rate. However, as I stated they were considerably more clipped than what was done to the Corsair.
