What is the advantage(s) if any to managing your own propeller pitch?

Better performance. Just like comparing a manual shift to an automatic in a car.

I have tride to manualy change the prop pich. But i didn't notice any performace increase. I use it to slow down in a hurry or decrease the prop pich to prevent overheat.

One test i did was in a LA-7. I flew in a circle, going around and around and around for about 10min. Turning as tyght as i could wihtout stalling the plane. I did this with combat flaps and flaps raised. With flaps raised 100% prop pich i was crusing at between 200 and 230kmh. I decreased the prop pitch to 50%, thinking that i might gain some performance or spead. Well, that didn't happen, my speed droped to 170. Almost stalling i increased the prop pitch to 100% and it brought my speed up to 210.

Note this is my first fying sim, i have been fying for only three munths. Almost two months online i think. My point is I could be wrong as to how i thought it would work, to increase performance.

So please set me straight if i am wrong.

The La7 has a cobstant speed prop. You will gain no performance by fooling with it's pitch. The best you can do is gain some economy by running a pitch that lowers the rpm. Like maybe 90%. Running a pitch of 50% will just make a dog out of it.

If you want to experience what prop pitch can do for your performance. Try a 109 G-10 as an example. Take off on auto pitch. Notice how sluggish it is on picking up on rpm. Now try again on manual pitch, and set it at 100%. that would be like 1st gear on a car. Notice has fast it picks up rpm, and speed. as you lift off, you'll over rev the engine if you keep it on 100%, so go to 90%, then 80% and so forth as to pick up speed. usually for top speed on the level a setting of 50-60% is good. Now start a steep climb. Notice the engine start to lug down. Shift the pitch to 70%. Notice the rpm pick back up. If the climb is steep enough, you might have to go all the way to 100%, but be careful as you can blow your engine easy by overreving on the 100% setting. As you level off the climb, braing pitch setting back to 80-75-65- etc. In a dive, it's easy to over rev the engine. make sure your setting is around 50-60% depending how steep the dive,and how long the dive.

It just like shifting a manual tranny in a car. I have two buttons progammed on my stick (throttle actually) for increase pitch, and decrease pitch. My thumb is on them always. I'm constantly shifting pitch up and down to keep the rpm in the 2500 range. After awhile you don't need to look at the tach anymore. You can hear the proper rpm of the engine. When you land just reverse what you did on takeoff. As long as your at low throttle settings just keep moving the pitch towards 100%, and it will act as a brake. With practice, it all becomes instinctive. Good luck.


btw..This is for German fighters. Most all the Russian/American planes have a constant speed prop. Just put those at 100% and forget it.

Well as referring to cars gears.

When you flyed in circles near stalling speed when you tapped prop pitch lower in % what you were doing was that you hitted higher gear .. thats why your performance degreased.

Near stalling speed you need all the RPM you can get, thus smallest gear aka 100% prop pitch. When flying straight and fast or decending bigger gear aka lower % prop pitch gives better performance.

Prop pitch aint working well anyways since you can fly with VVS planes 100% prop pitch and never can you destroy your engine with over reving it. Thus german planes have auto prop pitch so it should give the best performance for you. But again auto prop pitch is porked somehow for german planes so your not actually getting best performance out of your machine allways.

Sometimes you can get better performance with 103% power than 110% etc there are small quirks like that.

So wait for the patch and pray for ole... god that these things work like they should.

Don't move it Snoop. Just lock it if you have too. You delete all the posts when you move threads, and I don't feel like typing it all again. I hate typing.

Thank you so much, i have been to Mudmovres before but i didn't see anything on prop pitch or I coul't find it lol.

I did read about the prop pitch and understand 75%, ill understand more when I actualy apply what i have lerned.

I will try out the 47 because it's my favoreit.

Engine 2000hp
Combat 3,000rpm
cruse 2,550rpm

So this is what i gather so far. For best Combat performance I should keep the rpm at 3,000. To do this I use Prop Pitch.

Thanks again Snoopy, this is the first time i in three months that i understand prop pitch.


Thanks Silent out....

You didn't listen to what I posted. I was talking to you. The P-47 has a constant speed prop. Just leave it on 100%!

I flew the Emil almost exclusivly for a few months and really got to like the prop pitch. It was really nice when doing jabo because I could set the pitch to 100, kill the throttle and dive from like 4000m without flaps out. Had to be really careful to drop pitch to like 10 befor i got back on the throttle though/i/smilies/16x16_smiley-happy.gif

Soory about that BuzzU.

I just read your reply and you said you can just leave the prop pitch alone becaues the 47 has a constant speed prop.

The info you provided was informative, and gave me an eavan more understanding of prop pitch.

I need to lern to manuly apply it any because i try out differant planes. Like the LA-5, i think that has a constant speed prop as well.

Thanks every one for you help and pationts.... sorry can't spell lol

My point was you don't really have to worry about it unless you fly the German planes.

If you want to get a feel for it. Do what I said on the 109. If your going to stick with the russian/american planes. Don't even bother. Just keep it at 100%.

What is the best BF109. I kmow, what do I like to do BnZ or TnB but I like doing bouth. Or wich ones do people fly for differant reasons. I fly the Bf109 sometime's when i have to choose the blue side.

You were saying that it's only the BF109 that you will ony benift using manule prop pich?

Below is info on Prop pitch. I copeid and pasted it from Mudmovers.

Some planes have an automated system called constant speed propeller or aeromechanical screw that does not need prop pitch setting input from the pilot to stay in the power band. You may change from auto prop pitch to manual and back to auto when ever you like. You will have to bind a key for this function in controls. The auto setting is slower to respond to throttle input than when using manual prop pitch control. By using manual prop pitch control and throttle input properly you may be able to increase your acceleration rate and or maximum aircraft speed for a given circumstance better than the automated system. If you practice at improving your control over prop pitch and throttle input, you will get that extra speed to get that kill or stay alive.

After your done reading this, do you think that anyone can benifit form manule prop pitch using any plane that has the manuel option.

I'm not saying your wronge, but i just read this and thought i could benifit from using manule prop pitch with any plane. plus it wouln't hurt for me to try right.

I'm glad your not saying i'm wrong. I said nothing different than what you just quoted from Mudmovers. You just don't seem to understand what i'm saying, or don't believe me. Either one. I explained it as simply as I could. I don't know what else to tell you. I think you should just fly Russian planes, and don't worry about prop pitch.

I just lerned the hard way. I tride using manule prop pich on the P-47, whell there was absualty no performace gane. I just had to try, im stubern i guess. I just left it on auto afterward.
I will try out the BF109 tomorow and use manule prop pitch like you sugested.
Thankes for your pastionses BuzzU

Prop pitch in FB works best when done gradually. You dont see instant pickups in speed..in fact just the opposite...but you will find after a few minutes you are going faster with pitch at say 75% than you would be had you set your pitch to 100% and the same throttle settings.

Just remember that you'll get no responce with the Russian/American planes. Try it with a German plane. A 109 or 190. I recommend a 109 first. Try a G-10. Just like I described in the above post.

Remember im stuburn, so I tride it again and this time i spent 50min. I did what Bearcat99 sugested and waited longer. It turned out you were right again, i have a feeling you have already tride using manule prop pitch on other plane's.

I Set prop pitch to 100% manule and started rolling, when i was up left it at 100% because the Combat RPM for 47 is 3,000 and it was still at 2,800rpm. The rpm stayed at 2,800 the whole time. I can a shure you I had it on manule, i checked three times to make shure. When i got to a speed of 510kmh i decreased prop pitch to 95% and the speed droped to 500kmh. I waited for 3min and nothing happend. I decreased prop pitch again to 90% and the speed droped to 490kmph. I waited 2min and nothing happed. I kept on and finaly quit.

I noticed flying at an alt of 1000m it wouldn't go eny faster than 510kmph. I read some were that the 47 at sea leval could cruise at a speed of 650 or 680mph yes MPH you cant evan cruise at 650kmph.

So I think this plane was moddled incorectly on perpose or the persone who did the moddeling on it was vey sloppy and should be fired from Maddox games.

I know thats not nice to say, but how can you mess up on a plane this badly.

Silent out..

No prop plane can come close to 650mph on the level. You read it wrong. A P-51 Reno racer can only do 500mph, and it been streamlined, lightened, and modified to 3000 hp.

As for me trying the prop pitch on all the planes. Yes I have. I wouldn't be telling you to do something if I didn't know what I was talking about../i/smilies/16x16_smiley-wink.gif
