That could well be your problem...you may be doing teh equivalent of driving everywhere in "2nd gear". Lift the MP, carry more RPM and see if the situation improves.

Okay, would be nice to have the dat-file linked to the aircraft skin. But the solution works for me. So I collect different flying hours and maintenance hangar problems for further reuse

Hi Roadburner426 and seaniam81.
20 or 80 hours and worn cylinders?! I brought her around Africa and now I'm on my way to Australia, sitting in Indonesia at the moment. Flying her by the book helps a lot. So keep RPM low and set proper manifold pressure. Keep temperatures normal and you'll have a long running engine.

Thats it. You know we are talking here abot the best addons on market with eyes on nearly everything, but you have to move files manually, in my oppinion that should become an automatism. I never really got an ear by A2A for that.



Except "low RPM" i can also confirm no massive problems at my own online flight "from switzerland to switzerland without changing the engine" using real weather, maps and charts, I never go below 2000RPM even at low economic cruise setting as long as i have no increasing oil temp tue to wear. Also think about to take a rich automixture setting for step climbs at one leg.

I took a new P40B - departed in switzerland eastbound via russia, china (oil change due to another viscosity required), thailand, indonesia (safty landing, radiator and fuel filter changed), around australia, zig zag through new zeeland, some islands to japan (oil change due to another viscosity required), russia, alaska where i am now about to enter canada. 110 hours total time and according to maintenance report "beautiful shape". Compression test "all green". Had two legs flying above FL235 due to overfly an hazard at west coast of australia, the other high altitute cruise was due to range reasons, had to make 1400mn at one leg. The rest is maximum 3000ft AGL to see the beautiful sceneries and find roads to navigate.

Handle with care, take only power inputs you really need. Be clever and smooth in handling power inputs and prop pitch to control speed and temperatures.

"Low RPM" were the wrong words I think Normal cruise setting is better. I usually climb to around 18000ft with 2600 RPM and 35" MP and auto rich mixture. Then in cruise I use around 2350 RPM and 27"MP and auto lean mixture.

Next time, I'll take a testflight to see, what happens when running low on oil. There's only 20% left with a little oil leak.
Thanks to the saved dat-files, I can continue afterwards with the same engine as before but with a fresh shot of oil.

Great machine. Really looking forward to P-51.

Hi Killratio,

I did not go over you with my answer. It was just another example of motors in good condition for more than 100 hours in different conditions at about 20 legs.
I have no expierience on the real P40.

Not talking to yourself there KillRatio. I am reading. I have been caught up in the Mustang furor over the last few days though... I suppose you are right is maybe I am trying to hit the numbers to closely on things with the P-40. I had this same problem with all the other Accu-sim birds in the beginning. The Spitfire I kept eating crank shafts, the P-47 I kept blowing up motors, the B-17 I blew all the engines on the first flight.. I think the only aircraft that didn't give me drama was the Piper Cub. Then again you really have to try to wreck it. I burned up the engine in that when I thought I had enough oil to make my flight, and then I started watching the oil gauge bounce around (of course the engine then quit turning). My P-40 will eventually survive! Just need to put more time in it. Although with the Mustang on the horizon that may not happen in the near term.

Care to join me in a rousing game of "Get Off My Lawn?"

I'll even let you borrow one of my shotguns.

Can't be that old are you? Always figured you guys were around my age (late 20's).

I'm in the early 30s
And now back to topic.

Did a testflight to see what will happen when you're running low on oil.

At about 1 gallon of oil left in the oil tank, the oil pressure begins to slowly to drop.
After reaching around 40 psi, the oil pressure suddenly drops to 0 psi.





Now there's no time left until severe engine damage occurs. First I lost supercharger and then the engine deliverd no more power and I had to quit her going down for an emergency landing.
That was the result:


There was some time with low oil pressure, so you can save the engine landing immediatly or cutting it after total loss of oil pressure.
