bf109 radiator indicator rods are wrong (reversed)
 

Hi,

It appears that the functionality of the radiator rods on the wing roots are in fact reversed.

Here is an excerpt from the Messerschmitt manual for the Emil:
http://109lair.hobbyvista.com/techre...als/bf109e.pdf

Anzeigevorrichtungen fuer Kuehlerklappenverstellung auf Tragflaechen (versenkter Stab: Klappe auf).

Translated:

Devices for displaying the cooler flap adjustment are on the wings ( sunken rod : flap open)

The above doesn't appear to be a typo as the current inscriptions on the rods don't make sense as they line up with "Zu" (closed) when the rods are fully extended, which in the current implementation of the game happens when the radiators are fully open.

Right now when you close the flaps fully the rod disappears if you open them a little it says 'Auf' which is correct but then the fractions following don't make sense and the 'Zu' (closed) part at the bottom doesn't make sense at all as that only appears when you currently have the flaps wide open.

So to recap; the rods should be fully recessed, as in not visible, when the radiators are fully open. The rods should be fully extended when the radiators are closed. At the moment in the game it is completely reversed and appears to be wrong, going by the manual and by the inscriptions on the rods.

The mechanics would also make sense as closing the radiator would push a rod up through the wing if you attached one to the flap.

I noticed this mistake before with a couple of days. As I see, a topic opened already. Would be great if they would correct it.

Hello,

let me tell you as a native germanspeaker that "auf" (especially in this context) means definitely "open" not "up".
And it ist true what xnomad wrote: the pins are reverted in the game..

Horrido!

do not use the google translator, use just the google :)

Flaps up, pins up:

flaps down, pins down:

(pin aerodynamic drag? :grin: )

Ok. What may this mean then? "Zu" (Same sign, than on the inner reel arm closing direction ;) )

No, its half open (the half of the pin shows because of this). Look at these pictures. The flap is opened totally, the flap angle is much bigger (The pin does not disappear, you may see on top of him, that it's open (Auf)).

Absolut richtig!

That's correct, in this context "Auf" means "open" and "Zu" means "Closed" (btw. "up" means "Oben" and "down" means "unten")
The pin was simply adjusted at the flap, so when the cooler flap was down the pin was not very much to see, the cooler flap was up the pin was fully visible.

Here is a Picture from the Bf-109E3 at the German Museum in Munich.
The Flap is up, the pin is visible.

Here is another picture from the same airplane, which shows clearly the cowling flap is closed.

Interesting thread.

I hope this wld be addressed by the devs

By the way, yes the pin generate drag but it has to be compared to the weight saved in place of an instrumented indicator with all the pipes, fluids, bolts and brackets etc... Less weight, less drag ... Do it simple and light was Messerschmitt motto ;)

The E3B in the RAF museum. Radflaps Open Pin up :)

They should perhaps read the manual in that museum :D

There is nothing wrong.

In some parts the manuals of the Luftwaffe are a little confusing. Concerning the BF109E-3 radiator ... ...

"AUF" means "EXTEND" - If the radiator flaps are fully extended, the indicator / pins are extended (fully visible).
"ZU" means "RETRACT" - If the radiator flaps are fully retracted, the indicator / pins are also retracted.

Your explanation should convince the last doubter ;)

Happy landings
