Guys please help me out. The manual doesn't say anything about the Magnetos and prop pitch, and I want to know what they do. Also what would be a good engine load out to get the fastest preformence?

Well as far as Magnetos, just leave them where they are. In most aircraft with reciprocating engines, there are two spark plugs in each cylinder instead of only just one. One magneto provides spark for one spark plug in each cylinder while the other magneto provides spark for each of the other spark plugs. This is done for redundancy. There is a switch, usually along with the starter switch that allows you to switch between number one mag or number two, or both. Pilots normally fly with both since that gives more power/HP than just running on number one or two alone. But if one mag goes out during flight, you'd switch to the good mag. Then you will still have spark for one plug in each cylinder so all cylinders will fire. You would still have more than enough power to fly. So don't worry about mags. Leave them set to 1&2 and you'll be doing what most pilots do, which is nothing as long as the mags are ok. They very seldom fail.

I can explain about prop pitch too but I'll let someone else do that since there are many here on the boards that explain it very well and I've already typed enough for the evening!! I hope that explains the mag thing well enough for you.

Regarding prop pitch, start here:

is there a comprehensive list for all il2 aircraft as to when to switch to the next supercharger ? or what mixture is best at what altitude ?

to be honest, and im risking sounding noob here but i dont care, i always step mixture up at the same altitude as any other plane with mix, thus eliminating the need to learn all the planes seperately. For me, the magic altitude for changing mix to 80% from 100% is 3500-4000m. From 80% to 60% i change at 6000-6500m (or when the engine sounds in pain). I use the same rules for supercharger from stage 1 to 2. Never forget to change your mix as it will eventually kill your engine. Superchargers are just as important, dont step it up and a turtle would catch you if it had the chance. http://forums.ubi.com/groupee_common/emoticons/icon_wink.gif

Watch your gauges as you make changes. If you get more power by leaning your mixture, then you've done the right thing. If you get no change or a decrease, put it back or go the other way.

An easy way to go about it is to change things and see how it affects your performance... It seems around 3-3.6km it's a good time to switch gears on the super charger if so equiped.. look at the RPM guage.. if it goes down.. it's not time to switch... black trail of smoke behind you/running rough? Lower the mixture.

As far as prop pitch goes... well it's biggest purpose seems to be in fuel mileage... otherwise 100% usualy works for everyday use unless special situations come up... such as... slowing down and diving with certain planes.

I lean the mix when my plane starts streaming smoke http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif

S/C settings - I generally switch up between about 2500-4500m depending upon plane. Most US planes seem to want Stage 2 at about 2800m I find. I think the Ki84 is more like about 4000m
