Hi. http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif

Even with a F6F 5 (hellcat) a Tomahawk gets away from me!! I dunno why, but happens with many other planes. Hellcat is supposed to fly at 615 km/h at 7000m, and tomahawk at 575 km/h at same altitude.

Why does this phenomenon happen? Im going at max speed, max prop pitch with water injection, no overheat, no extraweight, no nothing!

Maybe they are scared of me http://forums.ubi.com/images/smilies/winky.gif

Are you flying offline?

Online you won't have that problem...offline, AI have 250 octane fuel...unless you fly against planes with manual supercharger settings...those don't know how and when to shift.\

AI bugs big time...hope Oleg addresses in the upcoming add on...assuming there is still one to be released.

Yeah playing offline, but i dont understand what u mean with "shift" and what is manual supercharger??

thanks

LOL...this will be why they run away from you http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif

In the controls area you will need to bind two new keyboard controls for use with the Hellcat, Corsair, and other types of fighters. You'll need a switch supercharger stage (up and down) key bind so that you can switch the stage at altitude. It varies on each of the different aircraft but with the Hellcat I think you need to make the first switch around 2500m and then the second switch at 7000m or thereabouts. I would have to check. In any case...at 7000m and above its safe to say that you'll want the engine on stage 3 in the Hellcat and Corsair.

Its like shifting gears in a car...except in this case you're shifting the engine supercharger gear for use at higher altitudes where the air is thinner.

So going with the car analogy...aircraft like the Hellcat and Corsairs have a manual transmission. Or rather a manual supercharger stage switcher. The pilot has to make the adjustment. Other planes like this include the Russian Yak, LaGG, and La series. Some planes like the Spitfire and Seafire have either a single stage and don't need to be switched or a two stage automatic so that it switches automatically. Other planes like the 109 and 190 have automated mechanisms that are continually modifying the supercharger settings.

But on the USN birds...the stages are manual. You need to make the difference.

Give that a try...you should see the engine RPM's rise as you switch stages at the correct altitude and you're speed will dramatically increase.

If you have complex engine management selected, some planes like the Grummans must be shifted by you at different altitudes to obtain best horsepower...other planes have no supercharger and others have autosuperchargers and shift on their own....

You'll have to map keys, but in a Hellcat for example...I shift from stage 1 to stage 2 at approximately 8,000 ft then again from stage 2 to stage 3 at 18,000 ft.

Hope that helps...we'll just have to be patient to see if the AI is addressed. Right now, they are faster, retain energy better, they don't overheat, no G limits and accelerate better than human flown planes....and again, those with auto controls etc...seem worse.

Where I really notice the biggest difference is at high altitude...say above 20,000 ft. A human flown Mustang will not out fly an AI flown 109G6late for example at 25,000 ft in terms of speed, climb etc...which is not remotely close to accurate.

Try online and aircraft will behave a little more accurately and pilot skill and fighting strategy/tactics will begin to dictate the outcome.

Hi Acersales.
With regard to the engine, American aeroplanes need constant throttle adjustment to maintain boost with altitude.
For example, with the F6F, if you're combat climbing from take off at 122 knots, 2700 rpm, 52.5 inches of boost, then as you climb the throttle needs to be opened to maintain 52.5 inches of boost until you reach 100% throttle. Here you reduce power, shift gear into blower stage 2, and start again with an initially lower throttle setting. When you're at 100% again, stage 3 can be engaged. The altitude at which this occurs varies from map to map. It's best to watch the gauges. Also, if 120% mixture is used on take off, don't forget to reduce this to 100%, as power is lost with altitude otherwise.
Hope this is of interest.
