View Full Version : P-38 inverted damage?

Hi, apparently the P-38 was only designed to be flown inverted for a maximum of 10 seconds before oil pressure was lost and damage was inflicted upon the engines - however, I can fly indefinitely inverted with no loss of oil pressure or other ill effects. This isn't a huge problem, but since the P-38 is my favourite plane, I was just wondering if there was going to be any fixes made? Any thoughts?

I haven't heard anything about this feature being added.

It probably wouldn't be limited to the P-38, either. I understand that most engines of the period (and to this day) rely on gravity for the oil, coolant, and/or fuel system.

Its not just the P-38...pretty much all WWII warbirds should be like that. Give or take a few seconds here or there. Inverted or more importantly negative G moves shouldn't be sustained in any WWII warbird for a long period of time.

Nor in my lawnmower...

Tipped it over to work on the mower deck and all the oil ran into the carb and cylinder head. Ended up rebuilding the whole thing! http://forums.ubi.com/images/smilies/16x16_smiley-mad.gif

So...real life tip...never mow the lawn inverted!

You mean I shouldn't have planted my grass upside-down?

The Lockheed P-38L is my favorite airplane.

I wish we can have this option. http://forums.ubi.com/images/smilies/88.gif

Aircraft of the WW II era were not designed for extended periods of inverted flight and doing so would surely cause a loss of oil pressure because the oil sump pickup would no longer be submerged in the oil. As far as I know this is not modeled in the Il2 series.

Another inaccuracy is the gun modeling in the P-51B/C/Mustang III. The 50 caliber machine guns in these versions were actually mounted so they tilted on their sides at about a 45 degree angle. This lead to feed jams if the guns were fired during a high g turn. Not modeled in Il2, but was modeled in European Air War.

The Il2 series has tons of inaccuracies when you start looking.

Like the climb rate of the 109K4 for example.

Or the top speed of the F4F.

I think it's the A6M2 that's too slow. I checked a couple of books and looked through some docs at Mike Williams site, and the IL2 Wildcat is within 5-7 mph of most of the tests.

A big, fat-*** gunsight blocking my over-the-nose view?

No thanks.
