  1. Wow, just like many people here I'm surprised we're not going for holidays in the Pacific. But in the end... The western front is just as exciting. Moreover my favorite engine is now coming... And in my second favorite bird ever... Can't wait to dive with that sweet P-47. I just wonder if this is gonna be the true razorback or the one with the bubble canopy. My heart beats more for the razorback <3 but i'll do with both :D. Really stoked to fly in late war american birds ! Preordering as soon as I see the release plan Thanks for the work done, and in advance for the work in progress, keep it up !
  2. Wow, there are a lot of great stories here ! https://www.youtube.com/watch?v=FhXz60f0HLU So far I have not flown a lot of sorties. I intend to change that fact very soon, and hopefully I will have a better story to tell than the following. Still, my most memorable flight was the one in which I got my first air kill. But this one was quite a special one. I used to go lone wolfing back in 1946 days. At the time I did not have enough time to be able to fly with a team with dedication. My attempts at flying fighters were pretty disastrous. So I decieded that I'd go for bombers this time. This was a late-war mission, and I thought i'd give the jet bomber Arado 234 a spin. With such a high speed I figured I could go bomb some fows without risking too much, and in the end finally being useful before going down. Bombs loaded, rocket assisted take off, and here I go, cruising around 700km/h. I reached an airfield and delivered my little presents. Destroyed a plane on the ground, turned back and went full throttle to try and avoid being caught. Unluckily for me this is when trouble begins, a Mustang that was at a higher altitude spotted me. I went in a little dive and then I leveled once I reached the max speed of my bomber. The mustang being not too far and having a lot of altitude, he still managed to keep up. My speed was forcing him into my 6, with a very smooth and predictable trajectory. I then thought, that, this being a MP mission on a sim, I could take some risk since my skin wouldn't get hurt. I lowered the throttle a bit while aiming at the bastard with the periscope. Once he was in an acceptable range he started shooting a bit. Fuselage took a few hit, but nothing too bad, I adjusted my aiming (kinda hard since it's inverted) and shot the rear firing 20mm. Scored a hit that killed the engine. My first online kill ! It felt fun to have it with such a strange device (periscope aiming, rear firing canons). I then proceeded to the base full steam. Safely landed, and I have not used jets ever since.
  3. I'm frankly quite excited about the Pacific ! I gotta admit that the B-25 will be missed in the begining. From what I read and remember there weren't mitchells at the battle of Midway, but the perspective of flying this legendary aircraft and reenact a "Doolittle" style raid in MP is so appealing
  4. Hello everyone, A few times, I noticed something strange. For the context, it was with a Pe-2 series 35. I do not know if it can happens with other planes. Spawning on map for a single mission, freeflight, on the parking. Now, when we start the engine (the whole procedure with the E key), well sometimes, when its cold, it stalls, and you have to try and start it up again. This is pretty much normal. Although, the whole procedure then goes with engine stop, turning everything off (would be funnier and more logical to try and give it another spin after some downtime to avoid flooding ). The problem here, is that if we hit 'E' to launch the restart too soon (before the stop procedure is completely over), we then are stuck in that state, E does not act in anyway to launch the "engine stop" or "engine start" procedure. And basically we have a "dead" engine. Maybe I'm missing something here, I don't know but I did not find anything about this on the forum (I searched Engine cold start combos), so I was wondering if anybody had come across this. In SP it's a non issue since, well respawn restart, done, but in MP it might be a bit trickier. Thanks in advance for clarifying this. EDIT : With the binds for engine 1-2-3 start/stop, this can also be overcome.
  5. Or undercarriage check ? Super legit on a Stuka Joke aside, I have not read anything about this so I'll be giving a thought about it. How is being a gunner in MP ? On paper it solves the logging as a lone wolf => flying alone issue. I am also quite interested as I am not getting a stick within the next 2 months and it could help me see some tactics, meet other pilots and stuff.
  6. Well, after having tested a bit, it is really hard to find the sweet spot for the perfect mixture. I did some experiments on the La-5(did I mention I love radials ? :D ). What I usually do is leaning while watching my RPMs, when they start to noticeably drop (by that I mean that you can see it on the meter, not 100RPM, so when the needle starts to "really move"), that is usually the moment when the flames go from yellow to blue. Now adjusting on the M82 is not particularly usefull since mixture 100% = automatic. But it can allow some savings during cruise. That mixture control skill seems (on paper at least) to be way more important in the klimovs who don't have any automated regulation. Thus I checked the Pe-2 with the alpha gauges (figured an instrument to match engine behavior with displayed A/F ratio would be more useful than testing it blind on a yak), and frankly it intrigued me. I know the oxygen sensor we use in the car industry were designed somewhen around the 60's, so I am really curious about how those 1940's A/F gauges worked. My instincts tell me it was a flow measurements comparison. Assuming they work perfectly, it seems that the klimovs are really gas thirsty since when the needle gets close while still being inferior to 1 (theoretically a bit rich, close to the stoechiometry), engines lose power perceptibly. An engine should not lose much power with a mixture close to the stoechiometry normally, especially a rich one, so I was wondering if these gauges were accurate, or if this a mixing issue (ie not homogeneous mixture in the chamber that would have lean spots and dampen flame propagation). EDIT 1: after further testing, the RPM starts to drop a bit (which is what I observed) when closing to 1 on the alpha gauge, but it does not result in a perceptible loss of speed, so I am actually not too bugged by this. It is basically a behavior similar to the one I observed on the shvetsov M82. EDIT 2 : some numbers added : Moreover, after a climb on the peshka, alt ~5000m, supercharger on 2nd gear, I set the mixture to get lambda around 0.9. Throttle down to get ~700mmHg of manifold pressure. The lambda ratio seems to be conserved. Now, with the same mixture lever position, I go full throttle, switch the supercharger to 1st gear (to simulate an increase of altitude without having to climb), get ~700mmHg of manifold pressure, but I see my lambda drop (to around 0.7-0.8). Thus I don't get how the mixing work. My idea of a basic carburettor is that the mechanical flow of air, goes through a venturi which results in a proportional pressure loss that sucks fuel in, and thus mixture is basically adjusted with air flow, so why do we have to adjust in this case ? Is the injection happening before the supercharger in this case ? In short, I don't really understand the Klimovs so far To conclude I'm in the market for some books about WW2 engines. Especially these Klimovs with their early lambda gauge, and the BMW 801 fully automated controls, so if anyone knows some good references, I'm interested. I soon will have quite some time to kill, and having a "productive" way to do so is appealing
  7. Hello everyone. As I am digging into BoS, I was wondering about mixture management, and I have a few questions for the in game experience as well as out of sheer curiosity. I have tried google and the forum search engine, but didn't find the grail. First, what does the mixture % displayed by the technical chat represent ? 0% is lean and 100% rich I figured by stalling engines and by the blue flames (complete combustion = less gas). But what does the percentage represent ? 0% seems to be close to actual 0% gas in the mixture, or, at least enough to stop combustion in the engine even when the propeller is rotating, but, what about 100% ? Is it linked to the properties of each carburettor/injectors ? All I know is it does not represent a fixed A/F ratio since adjustment is required with altitude, but I still wonder what it is exactly. Then, and the answer to the first question might be the key for this one : how to optimally use mixture adjustments to save fuel during cruise ? The only interests I see would be : a: of course, not flying richer than the stoechiometric ratio, as the cooling the unburnt fuel provides is useless at low power outputs b: engine load could be (partially at least) managed with the mixture instead of the airflow, thus we can get rid of some of the air intake friction losses. And to finish I was wondering how pilots were managing this (except the Germans and their fully automated stuff ofc ). Experience and "cuisine recipes" kind of tricks, or engineering sourced datas ? I thank you guys in advance for your enlightments.
  8. Hello there, I am a new player. To quickly 'introduce' myself, I am Max, 26 y.o from France. I used to fly a lot on the old IL2, and a bit IRL (~10h on a Jodel D112 and ~5 on an Aquila AT-01). I just bought BoS and I am enjoying it very much so far. Although I am nowhere near combat ready since : -a I don't know tacts -b I still fly on the keyboard just for TOs, navigations and some landings (gonna get my old X52 back in a few weeks, can't wait). Living on the other side of the Atlantic, I am currently unable to fly with you guys due to time shift. But as I will be moving to Vancouver next fall, I'd be really interested to join. My "planes of interest" on the red side are the La-5, Pe-2 and IL-2 (and soon the A20 too, l love pretty much everything with radial engines :D ) You can PM me for more infos, that would be very welcome. See you in the skies.
  9. Mmh for my 1st message, I'll jump in wonderland. I have a dream that one day, I'll be able to fly a Dewoitine 520. One day...
