The Re.2005 VDM situation is crazy

Is anybody planing a bug report considering the top speed? Also the lock up is horrible go over 630 and u are flying a brick, any idea why this is the case except gaijin nerfing?

For the top speed we can’t do much rn. We need some primary source to change it and we’re planning to get them in the Reggiane archives when they’ll open.
So until January nothing can be done for the top speed.

For the lock up I’m afraid it’s the same. Maybe we’ll check the books if there is some data about it.

it’s a problem of the vdm only

Gaijin found another way to nerf the plane, that’s all.

One advantage of my SM 92 is that i can fly the whole match with WEP - with 2 DB 605 engines. All u have to do ist to set both coolers to 50% and adjust PropPitch to 75/80/85% on H/M/Cold maps.

If you try this in a Bf 109 with the same engine - u will kill your engine.

That’s why top speeds of 109s are just theoretical values - AEC will close your coolers and your engine dies fast due to overheating - or the engine dies to overreving the engine with MEC.

I flew all of them on my old account, the G-10 had the best engine settings as i was able to use full WEP for at least 5 minutes with full power (AEC) before the engine started overheating…

An older post:

It is a matter of the (in)famous Einheitenverstellgerät - wrongly modelled in wt and (at least in past) in Il-2:

are you serious? dammit!

Sorry, does that mean that the engine dying is correct? And that Italian and japanese license produced DB 601 and DB 605 should die too if set with a wrong prop pitch?

No.

The so called Einheitsverstellgerät allowed prop pitch adjustments just in in a rather narrow range (~20-70%) - killing the engine by over-reving was irl technically impossible if the pilot stayed within the allowed rpms. Without these technical limitations (not modelled in wt) you kill the engine as the prop turns then too fast.

The idea of constant speed propellers is to have always the most efficient prop blade angle.

I found this old vid about the EVG:

That was always the issue - max rpm was set to 2.800. Just check the vid above.

That’s just German prop pitch.

The same thing happens with 109s, and it is safe to assume that since the Germans modified this Re.2005, it would use the same propeller settings.

It’s not really a nerf since prop pitch is automatic, you can just leave it as is.

70% prop pitch kills the engine once you reach ~300 km/h in WarThunder, because it makes the engine revolutions go above 3200.

Generally, this is a real PITA, but I’ve been doing like that for years with Ta-152H, which BTW overheats at most altitudes and to not overheatnyou have shave like 15% off engines output and since the game doesn’t simulate air getting colder at alt, it’s a constant struggle unless the map is winter.

To manage RPM you need a special, not banned by Gaijin software, WRTTI, which basically gives you RPM readout in the hud. Then you constantly adjust prop pitch to keep RPM around (depending on the engine of course) 75-90% of RPM and voila, and during fights you switch it to automatic unless you feel like adjusting prop pitch mid-dogfight.

Bigger issue of this plane is the flight model, which seems to introduce quite a lot of compression above 550km/h.
GL facing Yak-3U which is very maneuvrable at speed. Ta-152H you basically outturn and outclimb, so there’s that, but Yak-3U has this ridiculously big performance advantage. Now, you can’t BmZ at high speed, you can’t catch him and you can’t out-energy him. So times are.tough.

Sorry - i have overlooked this sentence.

If somebody has flown the BP Re 2005 upfront this update (adding MW-50) and confirms that the Bf 109 overreving issue was not implemented before the update i repeat my claim that this a nerf. If it was already implemented it is not a nerf - quite simple.

Arguing that prop pitch is automatic is imho not valid - simply because the idea of Manual Engine Controls (MEC) is to overcome either sloppy modelling of the thermodynamics of specific engines by gaijin within their Automatic Engine Control (AEC) or to improve flight and combat performance with using MEC.

Explanation

From a holistic pov every player is able to look up the charts and testing data of @MOBB and can tweak the flight performance of his aircraft by using the optimal settings.

The issue with 109s is and was always that they are more or less the only aircraft which have severe overheating issues which can not be healed or prevented by using the prop pitch / blade angles as an additional parameter as you kill the engine rather easy without managing your engine rpm via WRTTI.

So your goal with MEC is to find the perfect balance between WEP and engine temperature by adjusting via oil & water coolers (and their drag) AND prop pitch as lower blade angles puts less strain on the engine whilst the engine runs on max power to achieve the maximum sustained performance / speed.

Italian props (especially with radial engines) tend to overheat during take off. The redeeming factor of Italian fighters with German engines was always that you could manage overheating with cooler AND prop pitch adjustments whilst the same engine in a German 109 would die to overreving.

So if gaijin presents now a BP Re 2005 with improved engine power the question is simply if you are able to use this additional power sustained or not - and how long before you kill the engine.

I see this “special” treatment of Bf 109 as pure USSR bias and it seems logical that a plane better than the TT Re 2005 needs to get nerfed to protect the two undertiered Yaks at 5.7.

To make my point more clear - you can fly P-51s (C&D) with 100% prop pitch and 80% on both coolers / radiators and fly 25 minutes with WEP power without overheating (=infinite WEP).

This is highly unrealistic as there was no 80% auto radiator setting, just close / auto / open and prop pitch adjustments were possible within the 23°-65° degree range - and most decisive WEP was limited with max manifold pressure to 15 minutes…

Your claim:

…does not work with Me 410s - my most used German aircraft is the 410 A-1 - you can WEP the whole match with both rads at 50% and 80% prop pitch…

Whilst i agree with what you wrote - do you really see the necessity to make flying specific aircraft from specific nations much more complicated than all others? This is ofc a rhetorical question😎

And what is with guys unable to use 3rd party software? Asking for friend…

Have a good one!

Let’s stop wasting our time over something I hope is a bug (what did they nerf if the climb rate is worse, it turns slower, and the speed has increased by 2km/h since the Reggiane series 0?)
We ask a direct representative what is happening so that we can get some clarifications on the matter.
@Smin1080p_WT
it’s a bug or a nerf?

IMO this plane is dead in the water anyway. I bought it thinking it has good old Reggiane flight model. It compresses like crazy, so there’s 0 advantages over 5.7 Spitfire.or 5.7 Yak.
It turns quite nicely at lower speeds and that’s it.

But yeah, the general thermal behaviour of this plane is just a clear sign Gaijin wants it to perform badly.

I’m trying to trust Gaijin again, if they betray it again with this plane that I paid for with real money, I ask for a refund as European laws allow me to do in full consumer rights and adieu war thunder, I am not willing to tolerate systematic scams when I lose money, I can understand the normal TT vehicles, but I am not willing to accept a behavior with the premium ones, which since I have been playing have always proven to be overpower in terms of performance, and for any nation in the game.

idk what yall are on about i like it its a kinda like a 109 with better FM and actually good cannons just cause it has more i got a pretty good KD in it was dogging on P51Hs

Not always. Back in 2014 premiums were generally worse than TT aircraft.
Anyway, Italy continues its suffering.
Re.2005 VDM is really nothing special and 6.0 places it in a very tough spot.
With 0 effort by Gaijin to properly re-balance armanent we are still being effectively outgunned by basically everything.
I was hoping they will re-adjust the damage of autocannons to properly reflect their real life capabilities - nerfing most 12.7-25mm explosive shells while buffing 30-40mm and making MG151/20 M-geschoss one of the most effective 20mm cannon rounds. No such luck.

Majority of Aor RB players are bad.
But if you run into P-51H user who has even 2 working braincells, you’re never going to touch him. At least 2005 Serie 0 could surprise murricans with high speed reversals.
VDM? GL HF.

@Real_K_Soze and @D0N_SALVAT0RE
The Re.2005 VDM has the issue of ALL VDM equipped aircraft. It’s been like this since the times of IL-2 so it’s nothing new and was to be expected.
I don’t really know if historical or not, but it’s not a matter of nerfs to the Re.2005. It was not “nerfed”: it simply got a VDM propeller and that’s how it is modelled in the game.

At the moment the plane has a flight model comparable with the original for turning perfrormance, but with more hp. Obviously Irl it was probably faster and perhaps had a higher sustained turning time, but with the info we have rn it can’t be changed.

Re.2005 VDM vs Spitfire LF Mk.IX
Surprise surprise, the VDM can’t outperform a LF mk9 in a fair duel. It will probably be the same with the Yak-3U.
Honestly, if it could it would be too OP. Those two planes are mounstrosly overperforming for their BR and it’s not an unknow thing. Even with it’s true irl flight model idk if the Re.2005 VDM could outperform them, but complaining your plane can’t beat them is like complaining you can’t beat the Soyouz with a Iowa: it’s not a problem of your vehicle; it’s a problem of ALL vehicles.
VDM_LF

The flight model of the Re.2005 VDM now is at least adequate to 6.0. You will still out turn most planes while now having a functioning engine. Speaking of the engine…
I haven’t tested if the WEP time is infinite or the historical 20 min, but either way you are unlikely to run out in a standard match so that shouldn’t be an issue.
The engine now overheats in auto engine control while in WEP. In normal and cold map you won’t go past the very first yellow temp if you keep radiators at 100% with MEC with auto prop pitch so there the VDM thing isn’t a huge issue. I haven’t tested the plane on hot maps, but I guess it will overheat forcing you to lay off WEP periodically. That is indeed an issue, but I don’t see a solution for it that doesn’t involve having temperature data from the tests in 1943 or proving gaijin that you could use manual prop pitch with the VDM without the engine nuking itself as soon as you switch from auto to manual (I suggest making a new forum thread for that).
The silver lining is that the radiators are very good so as soon as you lay off WEP the temps will quickly lower by 10° and you can cruise at 100% with 30% radiators or something like that.

The plane is now fine and better than the Re.2005 serie 0 in most scenarios. Is it as good as it should be? No, but we can’t do anything without going to reggiane hoping to find new data. But is it a good plane? I think it is. It won’t be broken, but it will give most opponents a run for their money. So rejoyce and give it a chance: if you could make the serie 0 work, you can make the VDM strike fear in the hearts of stupid Yak and Spitfire monkeys.

OK, so basically it can’t deal with 2 most popular 5.7s while being 6.0
I remembered Re.2005 being great with high speed maneuvrability I guess it got nerfed to the ground at some point after getting boosted to 6.0, because going up in BR and getting nerfed is such a classic Gaijin maneuver.

Compared to 4.3 Yak-3 Re.2005 has worse high speed maneuvrability, worse speed and worse armanent, while having superior climb and lower speed turn rate.
At 6.0 it can, well, dogfight Spitfire Mk XIV/XVIII (just not at higher speed where I’d expect Spitfire to perform better) while everyone else is faster and performs better at speed.
J2M2 at 5.0 is better armed (less ammo but waaaaaay better ballistics), reaches similar speed, climbs better at low alt and I wonder if it turns better too.
La-9 while theoretically bad, has a lot better guns, a ton more speed and insane high speed maneuvrability. Re.2005 will have alt advantage, but will get reversed and outrun.
F2G has so much speed Re.2005 will compress if he tries to just catch up to F2G cruising at sea level.
P-51H can just sit there and laugh, if Re.2005 is going fast - an easy target.due to compression. If Re.2005 is going slower - not that difficult target and he has no chance of reversal.

Maybe at 5000m Re.2005 will have some advantage over Spitfire Mk IX and Yak-3U, but in general, I can’t see it performing that great while having the BnZ ability of Bf 109G6, speed envelope similar to Bf 109 F4 (I think G6 is generally faster than F4, because F4 has more issues with overheatibg) and decent turn rate that may or may not let it beat Ta-152H in a dogfight (my last fight in Ta vs Re.2005 was interrupted by 3rd party because my team disintegrated, as they usually do, when I don’t score several quick kills - I was getting firing opportunities thanks to landing flaps in a downward spiral and was able to reset the fight whenever something went bad just by diving a bit and dodging at higher speed).
