radiators have no influence on speed

And maybe it does..

But it may be due to pilot error, or it maybe so small that it is beyond your ability to make note of it, hence the need to log the data.

With that said

I noticed you didn't list your real world data reference.. Is it safe to assume you have one? If so, how much difference in top speed are we talking about here?

10?
20?
30?
40?
50?

If it is less than 50, now take a look at the resolution of the cockpit gauges.. That alone can be a source of a good +/-20mph error.. Just another good reason to log the data

As it should

Maybe.. maybe not.. No real proof has been provided as of yet IMHO

Well, Helmut Lipfert said the radiator flaps on his Bf109G slowed the plane down as much as 40-60km/h and used them sometimes to avoid passing a slower target. Anecdotal sure, but seems that the radiators would cause some extra drag thus less speed.

Just to be clear

I am not saying open rads should not cause more drag, and thus less speed

Far from!

All I am saying is that without logging the data, the sim pilot alone can cause a 40-60kph diff in speed. Thus the 'thing' you are looking for is in the noise of the human error.

One thing I want to try with the Spit & Hurri rads is to open and close them and check any change in climb rate. This meshes with what you're saying in a way -- it seems to me when I close my rad the speed doesn't change but by climb rate increases. Obviously, when I trim accordingly to keep the climb rate where I want it, the speed will increase.

However.......we've had a couple of beta patches plus the most recent retail patch, so I could be dead wrong on my observation above.

I have noticed the canopy open/closed has no effect on drag/speed. I tend to fly canopy open now for

1) better visibility -- especially in the Hurri
2) you can hear the DB601 supercharger whine directly behind you as a 109 is lining you up!

normally i fly with them as much closed as possible,to avoid engine overheating,while maintaining the minimum air resistance...
however i found out that one can leave the rads fully open and still reach and hold the top speed in level flight....

Oh my God!

And despite no drag from the radiators, the Huricanes are faster than us???

that should be looked into by the devs, cause i would assume that a fully opened radiator should cause enough surface to slow the aircraft down...


i have to say that this fact is extremely disappointing, as CEM and FMs are supposed to be the strengths of this game(sim?)

You've done testing, right? You've got evidence to present right?

Let's see it.

[Vengeanze]

Says nothing about working or not working rads on the box so...!

Poor Nancy

[David198502]

ace the only poor guy i see is you...you ask for proof,..why dont you just try it by yourself, or better why dont you proof me wrong?...i bet the reason for it is, that you dont even have the game.
so you tried it with your document you brought up,which you werent even capable of understanding,claiming a difference of first 5 then 11kph.
you claimed that one is not able of seeing the difference 5kph.i totally believe you that you are not able to.
then it turned out that its ten times the difference you first claimed.its absurd that you remained on your argument that one is not able to read a difference of 50kph on the gauge!thats ridiculous..
pilots would not be able to land an aircraft safely if that would be true.maybe you are not capable of doing so, but trust me, many others are.your incompetence has nothing to do with others abilities or inabilities.i suggest to you to buy the game and practise a bit, maybe one day you become capable of reading gauges and a difference of 50kph.

[SYN_Repent]

ace, your complicating things more than it needs to be, david never mentioned flying with the aircraft trimmed straight and level on the bubble, of course that would give more speed whether the radiator was open or not, his point was that havng the radiator closed did not effect his speed no matter what the attitide of the aircraft.

you have come here looking for an argument, dont you have nothing better to do with your time??

the graph YOU provided is evidence backing up davids theory, you even argued about that though you was proven wrong, you argued about the numbers being the wrong way round, ive read so many of your posts and this is just another of those where you make yourself look an idiot by being wrong and not being man enough to hold your hands up and say "hey, sorry guys, i was wrong here, maybe i dont know everything".

i was going to put you on the ignore list but you provide me with some comedy in a morning no offense meant of course.
