ENgine overheat
 

Please,tell me what to do in pacific,no matter japs or usa,my engine is always overheat! :(

What is your power setting? Prop pitch? Radiator?

If you're cruising, you don't need to fly at full power. It depends on the situation, but around 50% power makes a good "economy" cruise, and 70% for "combat" cruise.

When diving, reduce power and prop-pitch. You don't need 100% prop pitch all the time in combat either. A coarse pitch will actually get you a higher top speed, although with slower acceleration. Fine pitch (100%) is used for climbing or quick acceleration.

With these tips you should be fine. Of course, open the radiator if you must, but it will degrade performance.

Yes,ma frend thank u,but when im on 50% my scuad is already far away. Im talking not about dogfight. I mean the long range travels to the target,like the Pearl Harbour attack I have to fly over 200 miles :(

Your problem might be
1) maintaining an optimal climb rate (keeping up with your squad) until you reach flight altitude;
2) maintaining an optimal speed (keeping up with your squad) once you're at flight altitude;
Which one is your problem? And
Do you decrease mixture with altitude?
Do you reset the supercharger with altitude?
Do you decrease prop pitch with growing speed?
Do you retrim your plane for level flight?

Yeah, the AI in Pacific fighters travel way too quickly, and it should be treated as a bug. It can be corrected using placificplanes.dat file, or something similar. I forgot how to do it, so someone more knowledgeable should weigh in.

Thank u guys! One more stupid question(apologise): What is Mixture for? And prop pitch? And Trim?

I think this must happen to just about everyone at the start. Try this:

Keep your nose down after takeoff, gear & flaps up until you have at least 340kph/210mph. Then shallow climb to maintain that speed. When you get co-alt with your squad, start cutting back on RPM/prop-speed and throttle so you don't go blazing right past them fairly soon.

Nose high and slow, you make a _lot_ of drag. It's better to lose a bit of height to speed up than to mush along slowly if at all gaining speed.

^^ Pretty much this, in a nutshell. ^^

I'm willing to bet that most of the people who experience frequent engine overheating are almost universally those who mismanage their RPM settings. Some even firewall the throttle and prop in all flight regimes, and leave it there, even in a dive, thinking "the mostest means the fastest", then wonder why things break.

My wish for v4.13? Compulsory ground school for new players. You don't get to fly squat until you can demonstrate that you understand the basics in how planes fly, how engines and propellers work in aircraft, and how to get the most out of them. Hell, even throw in a bit of math and make 'em work on propeller efficiency and advance ratio, and so forth...

Take it easy, mate. As it goes now, attraction comes first, learning afterwards. More effective and motivating than the other way round. After all, we are only risking our nerves, not our lives. ;)
