just curious, how commen was the drop tank used, or the shackle for it fitted? ingame the same rack is used for 250kg bomb, 500kg and the drop tank.

from what little ive read, seems they where commenly fitted. mainly interested in western front for the info, eastern front info is fine too tho http://forums.ubi.com/images/smilies/16x16_smiley-wink.gif

If you want to know if it was a universal type of rack system for holding either a bomb or a drop tank, yes it was. From the the E-4/7B forward it was available on all models. All fronts.

The rack and mount could be removed and remounted in the field so it's extra drag wouldn't be left on the plane if it wasn't needed. That's why you won't usually see photos of planes with it on the belly unless it's set up for a long-range flight or bombing.

Those crafty German engineers knew what they were doing but I think it also shows how needlessly complicated advancing the 109 was getting to be compared to the cleaner and more advanced FW line. Purpose-built planes (along with anything else) are always better suited to the task than the Swiss Army knife types.

Ya - it's not like you ever see a big centerline bomb wrack(sic) on a 190 not doin anything, eh? http://forums.ubi.com/images/smilies/16x16_smiley-very-happy.gif

Sure the FW's had centerline hardpoints that were fixed, but what I was referring to was the the way (due to political considerations) the Germans just kept hanging more **** on the 109's and degrading their potential performance (not to mention the myriad problems it created in the nonstandardized manufacturing) rather than go with a more advanced, purpose-built design series that could do the job much better.

Wah, wah, wah,....the 1-oh-whiners have an over-romanticised view of the 109. The Wurger was the best. Kurt Tank just didn't have the political chops Willy did. Probably a good thing for the Allies, though, it's scary to imagine how far the 190 would have advanced if it had the support it deserved from the beginning.

I have been known to support the Cobras with an enthusiasm that defies common sense, so Kurfy can do the same about his pet plane if he wants.

There were two kinds of racks on the 109FGK. There was the faired, long teardrop shaped Schloss 503 (Rack 503) for the 300 liter droptank, which came with very little drag after the DT was dropped, only 4km/h at SL from my source. These could also carry bombs up to 500kg.


For bombs, the ETC 500 IX was used for bombs up to 500kg (theoretically, most 109s except except late ones had too little ground clearance if such big bomb was fitted, so 250ers were used). It caused more drag, some 12 kph at SL iirc.

Not 100% sure on the 109E, ETC 500 was certainly used, the Schloss 503 may have come later.

As for when to use - when it was needed. I suppose it was used quite commonly, but sometimes not. The DT worked on the 109 in a very simple way, compressed air was driven from the supercharger into the droptank, which forced the fuel into the main tank, so it was always full. The engine got the juice from the main tank all the time. No need for extra fuel pumps, extra systems, or to switch between external, internal, rear etc. tanks, no engine stopping because you selected an empty tank. http://forums.ubi.com/groupee_common/emoticons/icon_wink.gif
