  1. I can see in the note that the oil temp stays in the green with auto except on hot days with high power, that means it had reached it’s thermal limit. In DCS this is not the case on AUTO. This is exactly my point. I agree the oil should get hot at low speed high power demand such as a climb in the vertical. Great work on the graphs and charts and yes Yo Yo did a great job but like all things great they don’t last forever without updates. Give us 150 octane give us 82 In manifold pressure Give us dive speeds to .85 Mach without structural damage. Oh and fix the DM because that Gov failure model is darn right stupid. P51D Cadillac of the sky.
  2. Yes the 190 Dora runs hot oil in combat however I hardly ever need to look at that temp. However the P51 system should behave the same, it should not start the random failure clock when it go’s over the red line, If I open the oil cooler it’s really hard to get it to overtemp and cause this random failure mode. The Engine is now much more reliable and usually lasts the whole fuel cycle in combat manoeuvres. Unless hit by flack. Any way I’m over the P51’s cooling system, just need to stop popping engines in a casual dog fight. Open it and its fixed.
  3. Thanks for that report, i love reading that stuff. Any way test pilot are that test pilots and a large safety factor is added. But very interesting they mention the pourposing behaviour
  4. yes agree Simulate the pitch instability starting at 500mph below 10000 feet at 550 rip the wings off, as long as the axis planes wings come off at 530 mph we are accurate to the combat reports I am sure that the pilot was so fixated in the dive he never even saw his Airspeed anyway,
  5. grafspee the IAS is calibrated airspeed, when they design the pitot static system they calibrate it to provide the speed, this also compensates for altitude as the air gets thinner, Mach number is a combination of speed and altitude/temp so the speed of sound varies with altitude. The p51 has no Mach indicator, the Bell x1 post war had a variable pitch elevon controlled buy a jack screw and I think nitrogen to adjust its angle of incidence to allow the shock wave to pass over it allowing the pilot to maintain control through .85 mach .The mustang encountered the buffet and the propellor acts as a brake as the tip speed passed the sound barrier, the mustang cannot go through the sound barrier, no piston plane can, unless it's in space with a rocket up its backside. The combat reports are life and death reports, no test pilots liked to push the death side of the test, many died in the process of gaining faster than sound flight. Many WW2 pilots pushed the aircraft past designed safe limits. However if many many reports state over 600mph I believe them. They gave it all to fight for what they believed in (all sides) The results gave the americans the heads up to use elevons and push through the Mach .85 up to the sound barrier. Thin swept wings and elevons where now the jet age.
  6. Yes Art i can see his point, though I am an aircraft engineer by trade and high oil temps in any application over the max will destroy the lubricating properties of that oil, thats why its coloured green and we have gauges with colour only (for pilots) lol they are not the smart ones, the engineers are. Regardless of what the colour is at best rate the oil runs hot, yet the Auto door has not fully opened, Why? It is a simple thermostat, it opens the door at a set value of temp and closes it at a set value when the oil cools, until the oil cooler is at its maximum thermal efficiency right, disregard the colour, or gauge, its not part of the cooling system, its just an indicator to the pilot. So why dose the thermostat work at greater speed keeping the temp just right? If its a simple thermostat it should work like one and keep the oil temp at a set figure (engineer works that out) the manual switch is there as a back up for failure. so I am wondering why the climb is different, the door closes too much and the oil gets hotter the thermo switch should open the door to let more flow through the cooler (If Im climbing too slow) the oil cooler wont be capable of cooling any further right, No I open the door manually and the oil temps drop 15 or 20c ! that is my point. That set value must be wrong with relation to the thermal output and speed through the duct verses surface area of the cooler , its like the thermo switch changes calibration mid take off. Hmmm food for thought Yo-Yo WE still love the P51 but a little love hate going on at the same time. If the P51 cant be fixed just break Mw50 again lol
  7. I did not mean keep the temps in the green no matter what. For the P51 in combat (especially in Burning skies) you need to climb as fast as possible. So I use the best climb speed, But I can be pretty sure that at that speed the Temp should be under control with regards to the Auto position, Yes Max climb with max power I would expect the temp to rise. I don't dispute that, its just working against Axis aircraft that climb with no issues with temp and at much higher power settings. The designers have to make compromises with oil coolers and drag, the P51 was advanced for its day both in wing and Scoop design, the Oil system was no exception. If you climb at the Book Best Speed/power the automatic system should keep the oil at optimum temps, then when required (full mil power) you have some margin. Thats all, its just another P51 ism that is defaming a fantastic fighter. Oil, Prop Gov, Wings, falling off, 61 inches, 50 cals that ballistically feel like 303s Wheels up landings = instant death< all not Historically correct. They add up and all I hear in chats is I wish these issues where fixed. My 2 cents worth, and I know many of the WW2 flyers think the same. Please Take off with the oil and water in Auto, I know water gets hot, this was historically correct, and still is today. Climb at best rate as I describe, Be darned if your oil dose not climb well over the green arc to max, before you reach 6000 feet, If your at 85 c your not climbing at best rate.
  8. I think DCS is by far the best simulation for WW2 on the market. Period. I have read lots of reports and also heard 1st hand on WW2 allied aircraft diving to well past VNE, My step father said he though he went through the sound barrier in a Tempest V in a dive (impossible) but in those days that had not been done by any aeroplane. This canopy ripped off and Im sure at these speeds you would think you hit light speed. The mustang in a full power dive became unstable close to the hight MACH .85 .90 or so. This caused a shockwave to form and move rearwards as speed increased. As this shock wave reached the elevator on the P51 it caused pitch instability, the nose pitched up and down thus reducing the dive, the pilots new this buffet was the absolute limit (between 500 and 600 mph )depending on the density altitude.) Most pilots then pulled the throttle back and this causes the huge propellor to act as a air brake (god only knows how the prop Gov stopped it from over speeding) and they pulled out. 7g or more, Often watching the AXIS fighters wings come off before they pulled out. Any mustang pilot that didn't recognise this usually did not live to tell the tail. So why no make that Historically accurate? Make the P51 now pitch up and down and the engine work as a speed break like it really did. Don't just have a wing eject button at 507MPH or what ever it is set to in DCS. We need more WW2 pilots and Historically accurate models is the key. The war birds at air shows will never hit 72in HG unless your at Reno, thats on my bucket list. Thanks for your reply.
  9. Yo Yo thank you for the reply, Please don't take this the wrong way, I love flying the DCS Mustang and this model has given me a great insight into WW2 (my step Father flew 2 tours as Pilot in command Lancaster Bombers 56 missions and flew Spitfires and Tempest V ( was in 2 of the 1000 bomber raids over Europe) and downed 2 BF109s and one V1 doodle bug during the war, including D Day operations in the spit. Im a pilot flying helicopters for a living and don't fly any real warbirds however as a pilot I am sure the Oil should stay in the green ark in a climb at VY. So if you have to watch (manual adjustment) of the oil temp in the climb then its not AUTOMATIC. If the oil temp works in Automatic and if you just climb at best rate by the book it will climb close to the red line. Yes its under the limit, If you then level off it will come back to the green ark However if your flying in combat and you join a fight at the red line then your asking for an engine failure the moment you go vertical. SO I ALWAYS FLY OIL on OPEN until above 10 000 feet, this should not need to be the case as the radiator gets enough air to keep it in the green when open fully. Can you tell me then why have an Automatic system that is set well below the thermal limit for a 46' 2700 170MPH climb? This is not a full power climb, its out of the book where i would expect the system to keep oil temp in the normal range. As a pilot I would ask my crew chief for fix it before I flew it again.
  10. Yoyo I have flown the P51 in DCS quite a lot It is a very nice plane to fly. a credit to the team. Though I don't agree with that comment. If the P51 is used in AUTO both oil and water the temp for water behaves like it should. However the oil temp will climb out side the normal (green) operation range when you climb at Vy 170mph at 2700 RPM and 46 inches, This appears to be higher than the Auto radiator setting can adjust to. If you open the oil rad manually you get the oil back in to the green at best climb. This clearly shows the oil rad system is not at its thermal limit. I am pretty sure that the designers of the P51 would not set it that way, in fact from a pilots perspective this needs some tweeking. You should not need to run an automatic Oil system in manual with a best rate climb and this is just another bone of contention for the P51. JUST TO STOP ALL THE CRAP ABOUT THE P51, FIX IT It PLEASE this is an awesome model and very fun to fly. It's a handful in combat with the Prop Gov and WEP issues(fix that today please) and it will be much loved till the DM comes out. Please Please let this bird fly to 600mph in a dive and simulate compressibility (the pitch becomes unstable as the pressure wave meets the elevator) Many many reports confirming this. Don't Clip this fantastic machine! http://www.spitfireperformance.com/mustang/combat-reports/352-stearns-12sept44.jpg
  11. Eeks The stats server has locked up i think. I had 8 kills one loss and no change and the players on line drop down is locked on 4
  12. Agree I have noticed some players in the the top 5 seem to slowwww their attacks towards the end of the round for each season. Makes for interesting results. Now Flying today we (362nd) noticed the 109 has now upgraded its armour from a Tiger Tank to a Super TIGER and takes 7 or 8 planes to bring one down? Obviously a glitch in the DM but its was very noticeable today! On almost all of my fights today (5 Kills) of the 109 it was several planes shooting the K4 to finally get the kill and when I mean several I counted 8 and the K4 kept flying after all 8 Allied aircraft including the Spitfire Shooting all his cannon into the 109K4 with (Nil performance degradation) except lots of smoke. I know this is most likely a DCS issue as no one in their right mind would make the K4 harder to Kill. Perhaps consider to remove the K4 until this is repaired? Any other comments welcome?
  13. Great work EEkz. Seeing more players come in with the addition of the A8 and I16 has increased the numbers quite some. It would be great if you can back Engineer the problems with stats as its been that way for at least a month or more. See my post and Campbell's from 3 pages ago. Also on ELO its kind of good but kind of bad, if your fighting and its close to the end of the season and you shoot 3 lower rated players down and get bounced slow and low you can actually go down in stats points which it seems counter productive to engage.
  14. Stats Faulty recording Hey has anyone else noticed the Phantom stats issues. kills not appearing on the stats page, Flying and killing then landing safe and having a loss registered? recently I flew Killing 2 in stats, landed safe at base, quit the game and in stats I am shot down??
  15. Disregard Managed to get it working and testing now. Anyone reading I think DCS needs to be running to get the SAA software to stay open , then make sure ForceFeel is selected in Service TAB!. Im still not sure how i got it working as i had may errors saying cannot connect to Microsft Flight sim?? I clicked Ignore as I don't have it installed. Will try xplane 11 shorty. Form my first flight in VR its pretty amazing THX well done.
  16. Can anyone assist with SAA install? I open the set up, down load it and open the SAA then I get a small box that lasts one second "Verifying application requirements, This may take a few moments." then it closes the app. Basically it dose not start. Tried to reinstall it several times. I have windows 10 Pro. And my virus protection turned off.? frustration from waiting 6 months for the REALTUS SEAT then the software is not working for DCS?
  17. f410 thx do I install the control centre software then SAA ? or Just SAA?
  18. I wont purchase it unless its 150 Octane, they killed the P51D by putting it against a K4 and D9! Some where a village is missing its idiot.
  19. The P51 needs 40c Oil temp before flight in DCS or otherwise expect a failure. The oil Temp Auto switch will not regulate the temp with any effect. Watch on climb out at 46inches MAP and 2700 Max Cont power at 170MPH indicated Airspeed it will red line. Open the oil cooler and it will come back to 85c This is a problem for the DCS Mustang
  20. I have the Realtus Seat, Been waiting for the official SAA support for DCS, now its out do I install the Control Software from Realtus then SAA ( I want to use it mainly for DCS and XP 11) DO I use my Wings product key? Windows 10 Pro running on a Alienware 17 R4 with I7 Kabylake GTX 1080 32 Gig RAM Thx in advance
  21. The 109E at 400 MPH the pilot should have Very Stiff Aileron control to the point where pulling with all his strength can only apply 1/5th Aileron with the time to bank 45 Deg being 4 seconds This is from Test flights carried out on a captured 109E. Dose anyone know if this was addressed in later models? High speed dives where not the 109's strengths? ref http://kurfurst.org/Tactical_trials/109E_UKtrials/Morgan.html
  22. The 109 it has both ailerons shot off and out turns the P51 with no damage, Thats the point i make. The rudder turns it "Far" more than it actually could in real life I have placed hits on the 109 and it keeps flying without regard to the damage and out turns out climbs out dives. The P51 is awesome and I love flying it. I just wish the DM was even for the type. The 47 Jug was a tank
  23. The P51's great attributes seem to have been removed or rather neglected by DCS, its wings/flight control surfaces fall off at 505mph. Here is a classic example. The wings don't fall off at all. The P51 has hundreds of accounts of encountering compress ability well over that figure. So why have all the great traits been removed/not included on the P51. If I read the reports correctly they chased 190s /109s in a dive until the 190s/109s wings fell off. I like the fact that you need to be mindful of speed but Vne is a factor of flutter and the P51's flutter was mild compared to other WW2 Axis planes. So one of the p51s best defensive measures was to dive away. The K4 can climb faster as your initial dive is limited and you cant zoom climb as far then the turn fight ensures you get nailed with a prop Gov failure. They wont fight above 24 K because they are disadvantaged in turn and climb. Why have a Prop Gov failure anytime a round hits the P51s Massive propellor? The prop gov is a small component and located in an area that is very hard to damage. I fly the 51 a fair bit in Multiplayer and find that to be the most annoying. The 109/190s have a field day. Why not have this failure modelled on all the planes? Because "No one would fly them". Bring on 75 or 80 inches in the D model fix the damage model to be more even. And don't start me on the stall of the K4. The 109 was notorious for little or no warning on the stall yet the newby 109 flyers can pull that plane to its limit at 800 feet AGL and it has almost no accelerated stall. Yes it turns better, climbs better is lighter and had heaps more power. Power is heat, heat is death to an engine, The P51s auto Oil door is not working correctly. If you climb at 170mph at 46 inches 2700RPM in auto the oil will go to the red line. Sorry I would not accept this as a mechanic and pilot, as that is the P51's max cont power at best rate. Come on guys if you open the door it cools down. Why have an automated system that is Diss abled to the extent that it is? Bring on 2019 and fix WW2 and watch the sale figures soar! My 2 cents worth for 2018, 362nd Digger
  24. looks awesome Kez/Red must come play !
  25. 6th October and still no lables ! Any Reason? The dog fights are at cherubs height. The axis 109 K4s have a huge advantage. Get the fight back to 18 to 25 k as it usually ends up in the cherubs any way
