bf109 radiator indicator rods are wrong (reversed)

[TomcatViP]

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

The angle of which that picture is taken is nearly in line of the upper wing surface, so you can see the rod in is lower end position. The rods never sunk so much into the surface, that you would not see it (which makes perfect sense, as a indicator that can't be seen isn't good. ) This can be seen on the other pics showing open flaps, too.

Please all download the manual from the starting post, browse to page 47 and have alook at the picture marked "Abb. 60" (Abb. meaning Abbildung, meaning illustration") there the rod is shown, and you can clearly see that it just was a rod attached to the radiator flap. No gearing/whatsoever that reversed it's movement compared to the movement of the flap.

Its also written in the text just above the abb 60:

"Die Anzeigestange (60c) durch die Tragfläche führen und an den beiden Winkeln (60d) der Kühlerklappen (60a) anlenken."
"Push the indicator Rod (60c) through the airfoil and connect it with the brackets (60d) to the cowl flaps (60a)"


Also, "versenkter stab: klappe auf" on page 3 isn't badly chosen words. It says "open water cooler if needed (with crank located to the right of the seat); indicator on top of airfoil (sunken rod: flap open)". No german uses the word "Auf" for the meaning of up if the context is something you can open or close. Especially if "up" isnt "open".

!!! OKAY, CONVINCED !!!!

Thanks for that Druid.
This has brought up another inaccuracy, the rod should never be completely recessed, the tip should be visible.

I have a feeling that this feature is never going to be fixed considering all the bigger problems that need attention.

[IvanK]

Yes convinced as well.

Strangely the BF110 is modelled correctly. There is no reason to believe that the mechanisation between the 109E and BF110 differ. An excerpt from some BF110 handling notes prepared by the RAF



The equivalent notes on the 109E mention the rods but not specifically the mechanisation.

[Varrattu]

As an aside. The adjustable switch for the BF109E-3 propeller needs also to be revised. After pressing up or down the lever should automatically return to neutral. Look here:
