Hi all i just started playing IL-2 with the the advance engine settings. But my question is how do keep from the 109 f2 engine from overheating and stopping when i take off and when i'm in flight. I need the help. So how do i keep the engine working from takeoff to flying and combat to landing. Thx for any help

Keep the RPM under 3000 for short bursts of power and under 2500 for sustained high power.

Keep your radiator flaps on "open" settings all the time. Take off with 110 % throttle and climb to the altitude you want to cruise at (3000 metres is a nice cruising alt), then lower the throttle to at least 100%.

When you enter a fight switch the radiator flaps to "Open/Automatic".

It's best to cruise at about 80% so that your engine is nice and cool so you can avoid overheating too quickly when you need full power the most.

It's also good to have the radiators on "open" when you dive as this slows you down a little and cools the engine during your diving attack. Then level out and put them back on "Open/Automatic" and climb away again.

Oh and don't fly the F-2 the guns are too weak take the F-4, it has an armoured windshield so the view is slightly worse however, the nose cannon is 20mm instead of the 15mm in the F-2.

Maybe I misunderstood you, are you flying with manual prop pitch?

Not a good idea, I used to use it if I was desperately hanging from my prop in a steep climb with an enemy behind me, or to accelerate faster in a turn and thus turn quicker.

Then they patched this so now you are even more likely to damage the engine whilst doing this. Just don't touch the prop pitch the Bf 109's fly fine without it.

If you insist on trying then keep the RPM's under 3000, but you'll heat up very quickly on manual at such high rpms, really only use it in emergencies.

hey xnomad I'm using the last patch for fb but i haven't gotten the ace expassion pack yet. I just recenty ordered it. So my last patch is 1.22. Does that patch fix the engine problem? I don't know if prop pitch is on manual or not i just know that all the engine settings are turned on to complex. One thing for sure is that when i'm about to take off i set prop pitch to 100%. Is that bad or not?

That is bad (or not, depending how you look at it). You are in what is refered to as 'manual pitch mode'; this can be very confusing, so please keep in mind that different aircraft operate differently. However, for the Bf109 series (in 'manual mode', where you the pilot adjust the pitch), you MUST maintain correct engine RPM's by adjusting the blade angles of the prop (generically and often incorrectly refered to as 'prop pitch'). So if you look at your Tachometer (RPM indicator) and it reads 3200RPM, you may (will) damage your engine, lower prop pitch to decrease engine RPM. If you are at 1500RPM you are not developing enough engine horsepower (unless you are going for fuel economy) so raise the prop pitch. Each Bf109 (more or less) has a different 'powerband', or RPM range.

On another note, it is more historically correct to leave the Bf109 in 'prop pitch auto' mode, as all Bf109's had this mechanism to maintain engine RPM's by the time of the invasion of the Soviet Union.

It's not technically a problem. When operated on manual pitch, real 109's engines were ruined if allowed to rev too fast. If you choose to control pitch manually, you must be very carefull to keep RPM's at or below 2500 for the majority of the flight, and always below 3000RPM. It is for this reason that automatic systems were developed.

The auto proppitch came with the F-model and most pilots used that in dives, climbs and general maneuvering and that was the recommendation. This setting relived the pilots workload a lot and enabled him to concentrate on tactics and the battle instead of the engines survival. Also autosettings enabled the engine to survive a few flights more.
For Landings and takeoffs manual propsetting was recommended but not always followed.
While startin, taxiing and takeoff the radiator was opened fully and set to auto for rest of flight (opened if needed).

A few seconds of ovetrevving the engine will make it fault and soon die, wich is very unsafe if u have a long flight home.
-----------------------------------------------------

Some FB flyers claim that manual proppitch works best when assigned to a slider(like in RL), wich enables u to change pitch fast enough for combat.(key presses wont, although I have moderate success when doing carefull BnZ only)

Thx a lot for the help. I've been able to fly the ME-109 f2 without the hassle of the engine overheating. So i think i have a better understanding how to finally work the engine lol. Maybe i can survive in mp more. :-D
