@A.F. I can see your issue on tracks, thing is that when i hop in to K4 in my own mission or multiplayer server I can't replicate it. Everything looks normal then.

I just took K-4 for a ride and i didn't notice that, everything was as usual, no stuck blade pitch indicator during take off.

In cold start automatic governor is off, you need to switch it on

This is called human bias. But ppl still won't believe that nothing was changed even it is said so. I didn't notice any changes in FM personally.

Ammo detonation is thing which ED is developing so it will come to game someday.

I assume that worst case scenario is when air temp is very high and this additional temp increase in turbocharger goes above carb air temp limit. It is specifically noted in manual to take off w/o turbocharger when temps are high outside. It is indeed not stated anywhere in manual at what condition this up to 300bhp loss appears. This knowledge probably was passed via flight instructors. But my guess is that highest power decline will appear when carb air temp pass upper redline.

@razo+r Afaik we can not refuel tank separately like 50% in each tank. It will always top out wing tanks first. So if someone like to take 50% in wing tanks and 25% in fuselage he just can not do that in DCS. It would be nice to have this option since in many ww2 planes fuel tanks were completely isolated from each other and fueled independently each.

@Bucic Charger impeller is this thing on the left on each side view.. Those next to arrows on the right hand side are variable inlet guide veins. Those are for throttling supercharger in more efficient way then simple butter fly valve. High supercharger throttling is required at low alt and above alt when second supercharger speed kicks in. Jomo supercharger is gear driven single stage 2 speed so supercharger speed remain constant as long as engine rpm remain constant.

Because it is invisible mask. It still works. Lack of oxygen mask model is the least by far non essential issue with WW2 in DCS imho. And i hope that it won't be addressed until other pending issues got solved.

Ai is no better then player. Every time you drop a wing ai get one step ahead. Flying at high alt require discipline, patience and gentle controls inputs. Ai fly perfectly so it does not drop wings while maneuvering. But physics apply same for player and ai.

I could add that some ppl don't have hands too and they don't use joysticks. Maybe some more forgiving FM for them too ?

I made a closer look at this topic, and i can say for sure that struts are ok, but front tires are squishy as hell. Those are responsible for this nose down and left/right swing drop.

I literally jumped in P-51 on online server, i've lost my settings so i had to assignee axis and buttons again no adjusting curves or anything and i felt nothing drastic at all about P-51. I don't know maybe you should erase your settings and assign once again.

I tried P-51 yesterday and it feels more squishy. I think that front struts are much softer and this is the reason why nose goes down while braking. I didn't mess with brakes axis and i could manage with ease. Brakes maybe a bit sensitive but nothing tragic. Fully playable with some habits adjustment. If your intention is to adjust brakes axis so you can taxi it exactly as before this update, you will definitely fail. There is big change how P-51 behave on ground very noticeable at take off and landing but nothin unmanageable from my side. Only thing which had to be done are tires skid sound and tires roll sound.

I can add to discussion that even if i move throttle and boost lever at take off roll turbo does not spool up at all, it star catching up very late just before take off. Iirc early version of p-47 didn't have throttle/boost lever interconetion at all so we can safely assume that pilots at firsts use throttle and boost lever separately. Yeah this is the fact that DCS model engines way too sensitive, i could list couple famous examples but probably all of you know what i have in mind.

@Mr_sukebe, @Cool-Hand Exactly as you said. The worst spot to link throttle with boost lever is low alt range. At low alt supercharger alone is capable to provide decent boost. boost. With throttle alone you can get 46inch for take off, but even for full power take off procedure from manuals is to move boost lever to take off stop and advance throttle fully, this boost lever take off stop should provide that 52inch for take off unfortunately our DPS P-47 does not have boost lever take off stop. Manuals clearly says that at certain conditions up to 300bhp can be lost due to throttle/boost interconnection, i always use split throttle/boost, at higher alt i manage boost only with boost lever.

As far as i am concerned there are non. In cold temp when engine is cold it needs more throttle opening to maintain proper idle speed if you cut throttle in cold engine in plane like P-51, Spitfire it will just stall. During warmup fixed throttle position should result in increasing rpm thorough warm up. At low temp viscosity of oil makes engine rotate a significantly harder then oil is warm. Second thing is fuel evaporation when engine is cold fuel does not evaporate fast enough to take part in combustion. Those 2 factors makes that if engine is cold you have to push throttle significantly more to obtain 1000rpm idle then when engine is warmed up. So if you initially after start up set throttle to 1000rpm for warm up at the end on warm up engine rpm will go up, maybe to 1100 or even more. Another thing is throttle response right now it does not matter if coolant is 10C or 100C you have exact same throttle response. Manuals warns pilots to not over cool engines below 50C during descending for landing because when they ask engine for power at low coolant temp engine will likely fail to provide that power.

If you want obtain 64 inch you have to use boost lever even at SL. Power lose is up to 300hp but only between throttle/boost lever interconected and throttle/boost lever splited technique. Using boost lever at low altitude always adds power. Turbocharging is very or maybe the most efficient forced induction.

If you want high speed ground strike, you just need to start this from higher alt. 52 inch or 64 inch during dive makes little difference, as well you can use 42/2550.

I run up engines to 0 boost and i syncro rpm to get same on both engines before release brakes. This help with initial straight roll, then i quickly apply full power without detent activated. Can't remember how much boost is it.

Definitely piston engines in DCS deserve full package, not only smoke but all thing other things. Like transition from primer feed to carb feed during start up, if not properly done may lead to failed start up. Other thing like engine behavior in cold temps like sub 0C or even differences between cold running engine and warmed up engine.

I found some short airfield take full fuel and i managed to take off. accelerating above 100mph is possible.

Can you tell me from which airfield are you trying to take off ?

I think it wasn't ignored but "things to do" list is enormous and it waits for it turn

Make sure that you don't have any double bind for brakes.
