Hey TD can you look again at the Corsair..

[JtD]

What gauge are you looking at? The only valid one for speed figures is the big yellow gauge you get in cockpit off mode, as it's the only one to show the true air speed.

You should also always use 110% power for maximum speed, even if the real plane has slightly different manifold pressure limits for the various charger gears. Il-2 does not support a behaviour like this, so you'll see only one maximum boost figure on the cockpit gauge. But I'd expect the impact to be only small.

I've attached the il2-compare data for version 4.11.1. Blue is the F4U-1, which is in game used for the Corsair I, red is the F4U-1A, used for the F4U-1A, also representative for the Corsair II. The difference is the water injection. Both curves are for fully loaded aircraft. These speeds are valid for the Crimea map. I've been able to confirm these in game numerous times.

The figures you linked are not for a fully loaded aircraft, so if you want to re-test, I suggest a fuel load of 30% with default loadout for best approximation of real life test conditions, but again this will probably just make a difference of very few mph.

Thanks guys I'll have a look at that.

If i had a pound for every time people say planes are under performing because they don't know the diff between IAS and TAS regarding top speeds, I could of funded CLOD myself

True, but then it's hardly common knowledge...so in some ways, this forum can be educating.

Oh i agree, I never had any idea myself until the ubizoo, what seems (and probably is now) many years ago now.

@puma, with 50 cal threads you could probably pay of the national debt of europe.

I actually made this for that forum........

I'll see your IAS/TAS and raise you .50 Calibre's! I'd be able to fund BoS too!

Well Hell, that would explain it! I did not know that! I checked it out and sure enough you are correct sir. I had my FI gauge calibrated according to the in game speedbar mph reading. Excellent, thanks for educating me JtD!

Glad I could be of help for once.
