In the readme it says to shift gears at 2800m for the He111.

But the speed chart in Il-2 compare makes it look like it should be shifting at 3800m.

When I did a test in QMB it seemed to lose power when I shifted to second gear at 3000m, and the sound of the engine is weaker, but if I wait till 3800m it sounds good when I shift.

At this point I am thinking the 2800m in the readme was a typo and should have read 3800m, am I right?

I think it is as well. I spend alot of time in the He-111's and I get best results shifting supercharger settings at around 3500m.

Since most planes have different altitude ratings I toggle the superchargers while getting close to 2500k and check the manifold pressure gauge to see which one had the higher needle settings. When stage 2 surpasses stage one on the needle I'll leave it there. The trick is to not forget to go back to 1 when your bouncing someone =)

Did anyone see that or was it just me?

You're going to bounce someone in an He-111? I thought I was the only one that insane. http://ubbxforums.ubi.com/images/smiley/88.gif

Watching the manifold pressure is the correct way to judge...not by the sound. I'm trying to find an actual He-111 manual to see what it *should* be, but for now I've been going with 1.4 being the desired pressure.

If you watch the pressure begins to drop off around 2700m and by 3000 is down to almost 1.0.

Interesting side note: The Stuka is also supposed to switch at 2800m and displays a similar reaction. However, if you let the AI fly the Stuka it doesn't switch the supercharger untill 4000m--and the only way to tell is to watch the manifold pressure as the charger handle doesn't change position.

According to the original Ju87B manual, you were not allowed to switch to stage 2 under 3500m in a climb. The only exception was in critical moments, for example after the dive under AA fire if you had to leave the area very fast.

Well, it didn't just sound weaker, the rpms tweaked and seemed a hair lower, the prop pitch guage also tweaked. But the most telling thing was that while I was at 3000m in stage 1 trimmed level and switched to stage 2 my nose went down and I started diving and the nose didn't come back up.

The last patch mentioned the Ju88 engines/altitudes being corrected, and both it and the Ju87 use Jumo engines like the He111.

If you look at Il2 compare it is very very clear that there is a drop in power above 2000m and a surge back in power just a hair below 4000m. While the Ju87s shows that same drop above 2000m, but then they surge back at around 2800m. Then the Ju87 drops off again above 4000m (which is where the He111 makes its surge).

When I looked up the Heinkel's engine in google I couldn't find any critical altitude info.

I hope they correct it too. http://ubbxforums.ubi.com/images/smiley/16x16_smiley-happy.gif
