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.

At the end there is landing, you can skip first half.

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.

That is how i do it in all warbirds, approach higher and my final i do with throttle cutoff ofc you need to be quite proficient when to cut throttle to be able to glide to runway. I make landing like this guy.

I can't imagine to use 8 9 keys to control left and right engine separately during take off roll, thigs are going way to fast to pull this off with single axis and 8 9 selector.

I'm not aware of length of all airstrips in DCS maybe you are trying to take off from very short runway ? Can you tell us from which airport are you trying take off ? I tried on my end and i am able to get even 140 before liftoff, question is how long is runway from which you are trying to take off because some of them are quite short for mosquito.

If i cruise at high alt for long time i get this pitot failure very often only descending to low alt fixes problem.

Yeah ai is too good, average player is much much worse at flying in combat. So where in most games ai sucks and it is super easy to beat ai and online pvp scenario require a lot more skill in DCS is other way around heh. In pvp scenario it is most likely that you shoot down someone without he being aware of this.

Good point, it wasn't completely wrong afterall. Sorry about that.

You used term "always" this could be misleading.

That is not quite true, if you want to increase power first increase rpm after this increase throttle if you want to decrease power things are opposite, first you reduce throttle then you reduce rpm.

First you need to move RPM levers all the way forward before attempting take off. Then you can operate throttle levers.

I am much more amazed that he managed to climb to 30k at low blower speed.

Corsair is just different story. It is navy fighter designed for hard and difficult landings on carrier deck. It is totally possible that DCS P-47 landing struts are modeled too weak, but there is probably no way to proof that. So it is only up to ED if they conclude that model is right we will have to land P-47 very gentle.
