Full CEM with the Hurri...

Hurricane CEM...

Hi all

My first foray flying the Hurri with CEM on, ended in disaster with my engine seizing, me ending up at the bottom of the Channel. Thought I had it covered, but obviously not (t'was a Rotol Hurricane). How are other folks managing mixture, rpm, oil and radiator temps etc. Mapping the oil and radiator to keys did not seem to do much, is there any visual clue in the cockpit as to how much these are opened? Have no probs in the ME 109 when on CEM (mixture is auto, etc). I have been using a Thrustmaster throttle (good for modern sims), but am going to switch to a Saitek throttle with 3 axes and swicths. What are other folk mapping to their axes to help with CEM? A guide specific to the Hurri would be most appreciated...
Cheers

There is a little icon on the bottom left of your screen when you fly.
It has four or five sliders depending on aircraft, on the Hurri the last two sliders on the right are the oil and water rads, just put them on max and forget about them...(don't know if that works with a real Hurri, but it does in Clod). You can try to put them halfway to see if you go faster (less drag), but I don't think so.

As for RPM, it is managed with the prop pitch; set it the RPM you want and use the throttle to give more power, at same RPM.

The Rotol is a constant speed prop, it will vary its pitch automatically to keep the RPM constant, within limits. Take off at full fine pitch, then do like a bicycle, coarse pitch horizontally to pick-up speed, fine pitch when the engine strains, just as you strain going up a hill with your bike. Take-off looks like 3000 RPM, long cruise is 2200-2400. Don't hold 3000 RPM for more than a few minutes.

Mixture is one of two: auto-rich or auto-lean, nothing in between, auto-rich is most of the time and auto-lean is for long cruises at lower RPM.

Edit: The sliders icon on the hurri has the last slider on the right for BOTH radiators, there is only one slider and not two as I wrote earlier. Sorry for the oversight.

The 109s are far easier to manage than the British planes, only by ignoring his oil and glycol radiators and not opening them can a pilot overheat them easily. And the E-4 is pretty much automatic as far as pitch control is concerned. The British planes require a lot more management.

Both your oil and glycol temperatures are managed with your main radiator, which can be seen in the cockpit of both the Hurricane and Spitfire as the lever which looks a bit like an emergency brake on a car, located to the left side of your pilots seat. Pass your mouse cursor over the cockpit area and it will identify itself. There is no adjustable oil cooler on British planes. I would recommend programming two keys for open rad and the other for close, under game menu for OPTIONS/CONTROLS/AIRCRAFT you don't need this on a slider, since it doesn't have to be adjusted that often.

You can take maximum temperature for Oil to be 95 degrees C, and water maximum 110 degrees C, shown on the gauges on the center right lower section of your cockpit dash, oil and water are side by side. Oil goes to a max. of 100 C, Water to higher temps. Again, you can ID them by passing your mouse cursor over them.

Of the two, oil is the most important. Remember to let the oil warm up to 60 degrees C before you take off. Do not open your radiator till you see oil reach 60, otherwise it will take forever for the engine to warmup, then open it BEFORE you take off, failing to open it at that point will lead to immediate engine failure. Open your radiator fully, when you get more experience you'll be able to fine tune the degree to which you open it, but while you are learning to fly, you should just make it simple for yourself and leave fully open.

Prop pitch should be set to max. fine on takeoff for the CEM planes, which will give you 3000 rpm at full throttle. Once you are airborne, and your undercarriage is up, you should reduce rpms to 2800 for 100 octane planes and the Spit IIA and 2700 for the other versions. In the case of two pitch props, takeoff is in fine, once you are airborne, let your speed build a bit in level flight, and then switch to coarse pitch. If you want to climb in a two pitch plane, switch back to fine pitch. Do not dive with your prop in fine pitch in a two pitch plane, your engine will over rev and seize.

Throttle/Boost should also be brought back to less than maximum after takeoff, for continuous use under 10,000 ft, +5 is a good setting for the 100 octane planes and the Spit II, and +3 for the other types.

If you get into combat, you can increase prop pitch and rpms and bring up your boost, but remember to watch your oil and water temperatures and make sure they don't get too high. They will rise quite quickly if you are in a full on turn and burn slow speed situation.

Leave mixture alone, it starts in full rich, leave it there.

There are lots more elaborate and detailed flight how to's out there, if you search the forum, and you should also make a point to take the time to read the manual located in your "Program files/Steam/Steamapps/Common/IL-2 Sturmovik Cliffs of Dover/Manual/ folder.

We would be happy to get you up to speed.
