Err, hi,

Okay, now there's bound to be a really simple answer to this and I'll be holding my head in my hands in shame, but here's the prob:

Finally, I've decided to take the plunge and head off into the world of CEM. (I can hear the applause).

I assigned Prop Pitch Up/Down to two buttons on my throttle and Mixture Up/Down to two buttons o the keyboard,

And I set CEM to On in the Controls.

BUT When I flew my favoured 109, nothing happened. The prop pitch didn't change and neither did the mixture.

I'm sure I've set the buttons correctly. All the other buttons work okay.

So, am I overloooking something really obvious? I guess so, but what?

Thanks VERY much in advance,

Well first off all BF109 dosent have a mixture control.

Secondly the BF109 has automaitc prop.pitch control. But there is a button to turn this to manual.

I have my control settings assigned to my own type, so im not sure what the defualt control button to turn *prop.pitch autmatic/manual* is. http://ubbxforums.ubi.com/infopop/emoticons/icon_frown.gif

Hope this helps http://ubbxforums.ubi.com/images/smiley/35.gif

Stay away from manual prop pitch in 109's unless you can afford alot of beer for your mechanic.

Did anyone see that or was it just me?

Alotf of the Axis planes have automatic prop pitch. You need to bind a key switch between manual and autmatic prop pitch. I think the default is Shift+0 but i'm not sure.

You've picked either the wrong or the right plane to learn CEM on. Almost everything is fully automatic in the 109s and 190s.

Have a look here, maybe you'll find some things to help:

I'll be extending the sections on mixture and superchargers soon...

you must map a key for select auto/manual pitch, that will turn it on and off, then you must map keys for different % of pitch. you do not have to be in manual to select the pitch you want manual to use, select the pitch, then turn auto pitch off and the prop will change to this setting. I cycle the pitch so that the rpm goes to 3,500 rpm for a split second and then it drops back to 2,800. by doing this over and over again it will make the 109, climb a lot.......I mean a lot faster!!! the lower you are the more significant this is. it will make the plane turn better and also make it faster. a 109 on cem is like a totally new a/c, it only looks like the old 109 your use to. dont listen to these guys that tell you not to use cem. play with it and smoke a lot of engines till you know how far you can push the 109 before the engine smokes.

Unfortunately, I saw this on the Viks tracks too. No offense to either of you but personally, I don't care how much advantage it gives me, I will not exploit such wacky performance no matter what.

This is how i manage the G2.

Startup:
Switch to manual from auto
Prop 100%
Radiator full open for taxi and TO

Takeoff:
Normal:use 1.3 ata and 100% PP
Do not exceed MP 1.4 ata or 3000rpm (approx 91% power)

Climb:
Raise gear
Prop pitch to 90% do not exceed 3000rpm
(adjust pitch and AOA as needed for max or slow climb)
MP 1.2 to 1.3ata
Radiator to position 2

Cruise:
Prop pitch 60-70% (adjust higher or lower as needed for
max or normal cruise depending on a/c)
MP 1.2 to 1.3ata do not exceed 3000rpm

Combat:
MP 1.4ata 2850rpm (5 minute max) do not exceed 3000rpm
(if diving close radiators so not to supercool engine and
if needed decrease prop pitch to prevent overspeed)

Landing:
Slow a/c to approach speed
MP (Power) off
Inch prop pitch back to 100% in case of go around
(dont overspeed)
Gear down and locked
Radiator closed to keep from supercooling engine
Flaps as needed

Rollout:
Raise flaps for maximum braking
Radiator full open for taxi

Thanks guys. It's great to be part of a community where so many people are willing to share.

I'll give CEM a go with the 109. I like a challenge.

I remember when first flying (in IL2) how I would stall all over the place. But a few weeks later I was dancing around the sky (more or less!).

The analogy I use to think of manual Prop Pitch vs Auto PP is that of driving an automatic car vs a manual. And how the difference may not be so great cruising the highways, but around the hills (= in dog-fights) manual gives the right power at the right time.

Is this a useful analogy? Heck, who would choose to drive an auto in the hills?! Yuck!

Time to practice.

That is a PERFECT analogy!

Only one thing to keep in mind is the rather wacky reversal of what prop-pitch % means when in a "manual" type plane like the 109. In-game a high % actually means low or fine pitch (itty bitty bites of air to haul your *** around, i.e. low gear) while a low percentage actually equates to a coarse pitch IRL.

Just start out at 100 per cent and bind one key to increase and one to decrease the prop pitch.

S!
