Complex Engine Management / Oil on window ?

With temperature effects my engine likely wouldn't last very long

We have a problem because the Hurricane (and Spitfire) mixture outputs are reversed to what they should be.
Engine Start:
Set mixture to RICH in cockpit.
Be aware that currently the mixture selection is reversed in the cockpit, RICH = WEAK and vice versa. On the DH prop Hurricane move the mixture lever all the way forward until it is fixed when it will be all the way back. On the Rotol Hurricane, closing the Throttle also closes the Mixture to RICH, which is what it should do on both Hurris. But remember RICH is in fact LEAN atm so with the Rotol move the throttle forward to just clear the START label then move the mixture up to just behind it, thats as RICH as you'll get without over-opening the throttle for startup. When running, handle the Rotol Hurri throttle opening carefully, moving the mixture lever forward behind the advancing throttle as much as engine running will allow. This should all go away once the problem has been fixed. See

Temps for takeoff:
Oil temp: min 15'C
Coolant temp: min 60'C (according to Pilots notes)

Open Radiator until you are in a position to manage the engine temp with it (70C - 90C, max 105C)

Takeoff prop is usually 3000 rpm, max boost. Climbout around 2600 with boost reduced around 4lbs. Combat in the region of 2600-2800. Cruise anywhere from 2000-2400, typically boost 0. These are from memory of the pilots notes but they should help.

I'm also getting that shaking syndrome in the 109. It's an intermittent but permanent shaking and sometimes it eases off and sometimes it's really bad.

The only way I can make it stop is running the engine at full throttle. The prop pitch doesn't seem to matter. I've tried all settings of prop pitch but the shaking remains.
Radiator and oil radiator are open; sometimes I close the engine radiator a little but nothing I do seems to stop the shaking, except again if I run the aircraft at full throttle. Temperatures are normal. It's wierd.

I also have an info box open that shows engine damage, but according to the game I have no engine damage. (?)

This is strange Rattlehead, I've noticed some vibrations too with the 109, it seems bounded by a bad engine management but I'm not sure. I say that because since I take care of my engine, the plane dosen't shake as mutch.

If you have full CEM, try with your 109 to climb at 20.000 without any epileptic shaking, if you'll have success tell how to pilot this 109.

Sorry my mistake, I tried, the plane was shaking, and needles bouncing. If you disable the headshake, the plane will not shake anymore, but needles will still bounce. The only way to have a calm plane is to uncheck the CEM. When you cut throttle or when you go full throttle, the erratic movements stop. Bizarre^^

are you really sure about that? My hurricane seems to run best with the virtual lever, as well as the actual in-cockpit lever fully back - that seems to be my RICH position, as i can start smoothly, fly and fight smoothly with that. Leaning the mixture (from my PoV) only roughens up the flight, the engine starts to vibrate as if having failed ignitions, and it gets worse as I move the lever more forward.
Imo, I'd say the mixture levers in the Hurricane (Rotol, at least) are correctly implemented.

How high can you go with the Hurricane? All planes that i have tried start to shake and bounce at around ~3km height. Leaning the mixture only makes things worse

[Redroach]

I practised that rather intensively (sort of) and after some time, I was up to 24000ft where the hurricane attains its max-speed, according to the manual. And that was without having the engine run too rough. Don't ask me how I did that, I had the same problems as you at first, but I can say that 24000ft is still not the altitude for full lean mixture ^-^

I would like to hang in again into the "shaking" in the Bf109.
Is there any explanation for this shaking?
I try to play with the oil and cooler rad, but nothing actually changes.
So i ve no clue what i am doing wrong, to get rid of that shaking.

I mean the Bf109 has "automatic" mixture and using automatic charger.
So nothing to switch here.

Is it a bug or ....?

Good to bring this topic up, I'm still confused with this problem too. It really looks like a bug, because by switching CEM off or head shaking off you get rid of the problem. Full throttle and IDLE remove shaking for me is it the same for you Ivan?
