Mixture Controls in US Planes - Mod Request - sutts - 23.08.2009

I've been reading the original F6F flight manual and have been completely blown away by the engine management features provided by Oleg. While many of the less important items are not modelled e.g. battery switch, the majority of the major items have and seem to work pretty much according to the manual. Even the mag drop was correct! Hats off to the Oleg and his team.

I was surprised to find that while the mixture controls of several aircraft are modelled well, the US fighters seem to have only 2 settings modelled - auto rich and full rich. According to the manual, full rich should be rendered inoperative and no attempt should be made to use it. The auto lean and idle/cutoff settings cannot be accessed for some reason which is a shame as the pre-takeoff and takeoff procedures could otherwise be followed pretty accurately.

I was wondering if a mod would be possible to allow a lean setting in US fighters as supported in other planes. I believe it was possible in the real aircraft to manually adjust mixture too but the manual warns against this and states the auto rich and auto lean settings should provide accurate enough metering - manual leaning is not recommended unless the carb is badly adjusted.

I have no knowledge of the IL2 game engine but am a programmer and my guess is that there may be a file somewhere to link the mixture lever object in a particular model to a common mixture management routine? Perhaps auto lean cannot be modelled due to a reliance on bespoke classes but just a moving lever would be a start!

I guess I'm in the minority here but being able to fly a sim aircraft according to the WWII manual has added immensely to the immersion for me.

Thanks for any advice you can offer.

I'd also like to extend my thanks to all those who have contributed to the patches to date - it really is like a new sim now. Big Grin

Cheers,

Dave

Hi Sutts!

Nope, you are certainly not in the minority when it comes to flying by the original flight manuals. The IL-2 in the game is also very accurate when it comes to the original flight manuals, as is the F4F Wildcat. (I am sure all of the others are as well)

As far as mixture goes, you can set your mixture controls using your keyboard, or a quadrant if you have one.

I have my mixture defaulted to be keyboard Ctrl + the plus sign to increase my mixture and Ctrl + minus sign to decrease it, all the way to idle cutoff.

So basically I can lean my mixture to just lean of peak using my keyboard (although now I use my Saitek throttle quadrant...whatever works best for you)

And that is on the F4F, and to my knowledge it works for all the aircraft in IL-2, Axis or Allied.

Just go into your keyboard control keys setup and look for mixture rich and mixture lean and set it up.

There you go! Hope that helps you out!

Sadly it does not...
Only 100% or 120%, that's it ! Sad

I know exactly what you are talking about, but unfortunately the data that would need to be changed is contained in the FM data. Since it is forbbiden to alter existing planes...... In order to make mixture work on a particular A/C, it would need to be re-done in a new slot with corrected FM, DM, and weapons.

It's the same problem we have with a lot of the bombers not having fire extinguishers even though we KNOW they were equiped.

So the short of the story is no, unless someone wants to re-do all of the stock planes with new slots.

Thanks for all the replies. I tried re-mapping buttons to the mixture in the hellcat, wildcat and corsair and it does appear that 100% and 120% is all that we have to go with. Shame the stock planes are untouchables. Maybe one day....


Cheers,
