The Re.2005 VDM situation is crazy

I respect your opinion, and I want to clarify a few things before this turns into a pointless back-and-forth about opinions, pros, and cons regarding the Re.2005.

  1. We attempted to contact DB and BMW/Museum for historical documents. The response was that they do not provide information related to the WWII/National Socialist period.

  2. The sources I mentioned come from different authors and primary materials regarding the MM.494 and the Re.2005.

  3. Why would there be any issue or inconsistency with the Germans modifying their own engine? The DB605A-1 was delivered by the Germans and then modified.

  4. If you have the opportunity to modify and test improvements on your own products, why wouldn’t you take it?

  5. MW-50 was tested before 1944 and was used to improve the DB605A series engines. The DB605AM, for example, is essentially a DB605A-1 equipped with the MW-50 system, C3 fuel, etc.

  6. This brings us to the main problem: the Re.2005 MM.495 “VDM m,” as it is labeled in War Thunder, performs worse than the tech-tree variants, yet it costs money. Its performance suggests it should have been designated MM.494 instead.

“And if Gaijin releases a vehicle that you have to pay for, it shouldn’t be a made-up design like the current VDM. Just name it ‘mm.494,’ and don’t add an ‘mm.495’ unless there’s enough verified information to satisfy Gaijin.”

Period: Summer 1942
Event/key document: Start of experiments on the “Kühlmittelzusatz” (additive for cooling supercharger air) at Daimler-Benz and the RLM test center.
Engines involved: DB 601 E, DB 603 A
Primary source: RLM Archives, Daimler test reports

Period: Spring 1943
Event/key document: First official bench tests of MW-50 on the DB 605 A-1. Power increases of +15–20% were recorded.
Engine involved: DB 605 A-1
Primary source: Daimler-Benz AG, Aircraft Engines Test Department

Period: Summer–Autumn 1943
Event/key document: Preparation of the test report “Steigerung der Start- und Notleistung durch Ladedruckerhöhung u. Zusatz von MW50” (“Increase of takeoff and emergency power through boost pressure increase and addition of MW-50”), relating to the DB 605 G.
Engine involved: DB 605 G
Primary source: Daimler-Benz AG, Stuttgart-Untertürkheim (≈ July–September 1943)

No one is stopping you from saying it, just as I’ve already pointed out, we’re not here to hear this point of view. If you think you’re right, create a dedicated topic. Your current behavior is that of a Real Madrid fan cheering for his team from the Manchester United stand.
the thing itself is anachronistic

The only primary documents are for the earlier 494. All of the claims about the MW-50 equipped engine are secondary. And it’s not clear what, if any, primary source documents that those claims originate from.

The inconsistency is that it is highly unlikely that they
would opt to test out their cutting edge engine tech in an Italian airframe 3-5 months before testing it in their own. It does not make logical sense.

Nobody is debating this point. It’s just that the most likely modification of the engine has nothing to do with boosting it with MW-50, but rather production changes incorporated in 1943 to allow the engine to more reliably run at its rated horsepower.

I have never claimed that it wasn’t tested prior to 1944. If you have paid attention, my argument has been that the Re.2005 flight test pre-dates the German flight tests with MW-50 and by pretty important margins.

Again, I respect your opinion. Right now we’re only discussing what you think and whether that opinion is correct or not.

Fact 1: The plane in the game is the MM.494 with a VDM propeller installed — look at the manuals, posts and to my earlier suggestion.

Fact 2: The primary sources we’re using come from the MM.494 and the Re.2005 — again, see my suggestion and previous posts.

Fact 3: We’re no longer talking about what’s wrong with the current Re.2005 VDM. Instead, you are speculating about if the Germans had modified the mm.495 or not, and you’re treating books on the Re.2005 as if they aren’t valid sources.

And you have to pay for a fake vehicle.

“Als Vorteil der Fiat G 55 erscheint, daß die Zelle für den
Einbau des DB 603 sehr geeignet ist. Damit tritt eine erhebliche
Leistungsteigerung ein und der vorhandene Nachteil, daß sie
in der Geschwindigkeit unterlegen ist (ca 25 km pro Stunde Lang-
samer als Bf 109 G 4 und Fw 190 A 5) wird überholt. Es kommt
hinzu, daß das Flugzeug zusätzlich eine 3 cm Kanone auf-nimmt
.”

As an off-topic aside, I think it´s interesting that the Germans assumed a future G.55 equipped with DB 603 would also receive a 30mm cannon, at least according to the somewhat ambiguous wording of that passage.

so whats the diff between the VDM and the tech tree

It’s the exact same pretty much except a different propeller cowling and being worse performing.

You are paying money and a considerable amount of time to get a worse product than you get free

IRL the mm.495 had an improved engine and could reach 720 km/h (according to a German test pilot and the math of the people in this thread(

The re.2005 VDM in game has a climb rate of the mm.494

Altitude Time (s) Rate (m/s)

2000 m 1’58" = 16.95 m/s
4000 m 4’05" = 16.33 m/s
6000 m 6’33" = 15.27 m/s
8000 m 9′42″ = 13.75 m/s

Total max weight 3560kg

max-V 628.5km/h

The normal re.2005 serie 0 should have a climb rate of:

Altitude Time (s) Rate (m/s)

2000 m 1’35" = 21.05 m/s
6000 m 5’30" = 18.18 m/s
8000 m 7’50" = 17.02 m/s

Total max weight 3610kg

max- V 650km/h

And you pay money for a vehicle that doesn’t exist

so can we prove that re2005 495 did install the engine with mw50 thats the best and main objective of this post

if you find evidence for the MW-50 being on this it will be adjusted

2 Likes

do you guys have any photos of the engine or it being built ?

this is what the tank for the MW.50 looks like including pipeing to the engine so if you can find this youll have your stuff

definitely bug reportable

pilot reviews cant be used as evidence sadly but you can definitely use documents

I think so, someone just needs to make another report

We are waiting for the Reggiane archives to reopen in January. There’s a document called “MM495 with VDM” se we hope to find some useful info.

Other than this, we are waiting for a guy to go the italian airforce archives to check if there’s something there.

A second bug report was made Community Bug Reporting System
Please go and click “I have the same issue” to boost it.

Hello. The developers have reviewed the report in full. The engine was modified. A water injection system was added and boost was increased in emergency mode. However, this resulted in a slight increase in speed, which is to be expected. The top speed has increased to 652 km/h. The current weight aircraft is 3,600 kg, which requires no changes. The only source to mention speeds specifically for the 495 prototype was referring to indicated air speed. So sadly this was not an accurate measure. The remaining materials presented are not related to the characteristics of the 495 aircraft prototype. The above listed changes will be released in the next major update.

This response still angers me.

While the bug report does contain information on the MM.494, it is ONLY because the performance of the in-game Re.2005 VDM is based on what the MM.494 achieved.

Even now, the new 652 km/h speed is based on the 629 km/h top speed of the MM.494 but with the additional horsepower of water injection.

In short, that last bit of the response is insanely hypocritical, because Gaijin is actively using information on MM.494 to model the vehicle EVEN NOW with the boosted engine and VDM prop which the MM.494 never had.

More information spesific to the 495 is always welcome, however this is the best possible outcome with the current provided information. All viable information is currently being used to make these improvements.
