need proper report My list of possible bugs in DCS Mosquito

J13 Serenity · August 18, 2023

1. Drop tanks might have the wrong amount of fuel in them see this link for the other topic

4. When Fuel tank gets on fire, after a short period of time the wing just disappear. No explosion, its no even breaks. Simply vanishes.
3. When you engage an electrical fuel pump, even though the long range tank is empty, the red low fuel pressure light on the right side of the panel does not lit.
4. Even when you run out of fuel, the "Fuel pressure warning" light never lit.
5. Emergency landing gear extraction system cannot be used.
(I feathered both engines, gear comes down about halfway, I pressed the emergency extension, but nothing happened, there is no hand pump)
Also, the emergency gear extension push lever is labelled as a manual hand pump on the pop up message.
6. On spitfire, if no fuel pressurisation and no electrical fuel pump, after 10000 feet engine gets fuel starvation
On Mosquito, you can climb to 30K+ and everything works fine without pressurisation. Does it work as intended?
8. In the manual it is stated, that there are two engine driven hydraulic pumps, but even one is enough to supply the system, although at a "Reduced rate". Well, I feather one engine, and there is no difference in gear/flap/Bomb bay extension/retraction, even if I do all three simultaneously.
Also, Manual pumping has a lot of applications, so it should be implemented in DCS. The whole hydraulic system right now seems like a place holder
9. Generator low voltage light is very dim, even at night it is hard to notice.
Only bomb bay open light cover can be opened. But many other light always have their differ on with no way to remove. They should be made
clickable for day flying.
Also, the same Low voltage light keeps flickering on and off even during normal operation, is that "working as intended?"
sounds. I wonder if this Beam approach in Mosquito is just a place holder.
11. From what I understood from the manual, the radio requires HI voltage from left engine dedicated generator
Well, after tuning the beam approach and DF, I feathered the left engine, but all radio equipment kept working.
Is it a bug or my misunderstanding?
12. Sometimes the gun fire sound gets stuck and is neverending. The only way to fix it is to open a side window!!!? and cycle the trigger!
13. For some reason, the plane, sometimes, requires full rudder or aileron trim when carrying symmetrical bomb, rocket or fuel tanks loads.
For no apparent reason, the plane is heavily out of trim until the ordnance is dropped, including empty or full fuel tanks...
14. UV lights can be turned on no problem, but if you cycle them off and on again, they never get lit again and fade. Is it a bug?
15. Maneuvring without over G at speed above 300 miles per hour indicated is almost impossible without, eventually, breaking the plane.
Due to high sensitivity and very efficient elevator controls, as well as the absence of any G load indications, any, even slightest loss of vigilance leads to over G and a crash.
I do not believe that Over G on Mosquito can be attributed to a "Skill issue"
The controls efficiency and feedback are not "Coded" correctly and safe maneuvring at high speed is simply impossible at its current state, unless you have a force feedback joystick.
16 Damage model is also questionable
Mosquito catches fire very easily, even from a MG. Almost any cannon (20-30mm) shell leads to both engines oil leak, both radiator leak, multiple fuel tanks leaks. Its hard to properly judge the resilience of the Mosquito in DCS, but, compared to any other WW2 modules, mosquito is one of the easiest to destroy. Spitifre can survive a long MG burst or a few cannon hits. Mosquito - almost never. Somehow, its always both engines that get damaged at the same time...

Multicrew:
1. Some instruments are not synchronised with the navigator
From the navigator seat:
1. Rate of turn indicator always centered and doesn't move
2. Aileron trim indicates 2-3 notches left from the pilot indicator, elevator trim indicators are also not synchronised
3. When external view, landing gear can be transparent for the navigator.
4. For the navigator the pilot radio is always off, including the lights on the actual radio box.
Also, right not, the Navigator cannot use pilot's radio for SRS communication...
5. It is possible to use ADF for SRS communication, but for pilot and the navigator the frequency is always 0.001 off
for example pilot has 1300 KHz and navigator has 1301 KHz and only one of them can actually communicate on that frequency.
6. Sometimes, when pilot feathers the engine, for the navigator the prop is spinning, and he has to feather the engine as well for the prop to stop.
7. A weird bug (possible) when flying multicrew we started on outer tanks, after switching to inner, after some time, flying on both engines, from the pilot perspective left inner fuel tank reads higher then the right inner tank. While for the navigator they are the same.
For example, for pilot there are 100 gallons in left tank and about 20-40 in the right. Fore the navigator - both shows about 110 gallons
So the navigator total fuel is higher then the pilot
Then pilot shows both inner tanks zero, engines stop. But the navigator still has 20-40 gallons in each inner tank...
8. Sometimes the engine might be stopped for pilot but spinning for the Navigator. All engine instruments are also not synchronised.
9. Another weird possible bug:
When a player connects to the server and jumps directly to the navigator role, he is not assigned a "Faction", and his nickname can be seen as both the navigator and the spectator...
That leads to a bug like inability to use SRS radio, because the player is considered to be a spectator...
In order to fix that, a player has to select an pilot role on any other plane, before jumping to the navigator seat.
10. When playing as a navigator on the multiplayer server, if you click on a spectator, nothing happens.
Once again, you must select a different pilot role before you can exit the mosquito navigator seat to the spectators...
11. Sometimes, when playing as a navigator, at night the landing light are not visible.
Pilot can see them, other plane crew can see the landing lights, but for the navigator, the landing light of his own airplane are always off.

2. Long range fuel tank in the bomb bay cannot be fuelled and used...

There is no long range tank fitted.

I saw this yesterday and thought it a well detailed little bug list. I also thought “I wouldn’t hold my breath”.

The Mossie seems to be relegated in the things to do list. Most of it’s great but…

I watched a good doc earlier today on the Mossie. It got a bit sore to hear different pilots talking about how she was the fastest thing in the air and how it could outrun almost anything. I’m a sitting duck in the Mossie unless I just dropped from a few thousand and held the speed.

The proverbial DCS fortnight can take a long time in coming but I still hope for fixes or dare to dream, other variants, someday.

I wouldn't be surprised if those accounts of outrunning everything were from before the D-9 and K-4 were rolled out to front-line squadrons. We have a bit of mismatch in eras regarding our WW2 modules.

Mosquito will never be able to outrun almost anything because most common Axis plane, which you can meet in DCS are Bf-109 K-4 and Fw190 D-9 which has similar performance to P-51 in terms of speed. And P-51 is much faster then mosquito no doubts.

In war time K-4 and D-9 were the least common planes which can be meet in air. And a lot slower or similar performance planes were extremally common on Axis side. Even pilots operating while K-4s and D-9 were in use, they still got very slim chance to meet those in air.

And in Twin engine group mosquito probably could out run anything, and we need to consider numerous Mosquitos variants used during the war with very different top speeds.

Other thing is why Devs made decision and model quite early Mosquito when Axis side has very late war fighters.

Why not make Mosquito MK XVI with merlin 76/77 engine with +1700hp each and top speed much higher. Why not just wrap late war planes set and move to early years, this thing i will never understand, makes no sense for me.

I am member of this forum for quite time, i saw a lot topics about P-51 being not as fast as pilot's statements and common knowledge.

Same thing here, P-51 D was later version before there was Allison powered P-51A which was fast as devil low to med alt then was P-51B/C powered by licenced build Merlin engine by Packard V-1650-3 and later converted to -7 engines and then D version with bauble canopy and other improvements like stronger tail control surfaces and changed angle of incidence of horizontal stab to prevent porpoising effect in high speed dives.

P-51 A and B/C were much faster then Axis planes and from those encounters common knowledge tells us that P-51 was much faster and it is truth.

K-4 and D-9 was axis response to allied planes like P-51 and other to match their performance. And here we are in DCS for decade player in P-51D (which is actually a bit slower then older variants like B/C because bauble canopy takes couple miles from top speed ) could only meet the state of the art K-4 and D-9 the least common planes in wartime and the only planes in DCS from axis side which in some aspects surpasses P-51.

And impression is complete opposite to common knolage.

A good argument for a better set of WWII modules.

I’d love to see the period better represented in DCS. It’s as if their history books have half their pages missing. There’s little or no interest in much pre-44 let alone stretching back to 1940. I was talking to a retired RAF pilot recently, making him laugh at what I get up to on DCS and he asked if I had a Hurricane too. I don’t see us ever getting any, especially without better matching sets of modules for both Allied and Axis sides.

@grafspee, you mix things up regarding the Mosquitos. Mk XVI is B.XVI - it is an unarmed bomber optimized for high altitudes. It comes from a different development line (different prototype) than our FB.VI. In addition, FB.VI was special by being optimized for operating at very low altitudes.

While the top speed of the B.XVI is significantly higher (30+ mph) than FB.VI’s, it is achieved at nearly 30,000 feet. At sea level the FB.VI was the fastest mosquito model.

FB.VI entered service in May 1943, and changed very little to the end of the war. In 1943 and at low altitudes it was faster than any Lufwaffe fighter - the contemporaries were 109G6 and 190A5.

By mid 1944 the speed advantage was eroded, and day intruder/ranger mosquitos were equipped with 150 octane fuel and engine boosts of +25 (our does +18). This again pushed the FB.VI to be faster than the Luftwaffe fighters (109G14 and 190A8 by then).

By the end of the war, the latest LW fighters 109K4 and 190D9 were as fast or faster than an FB.VI even with 150 octane fuel. However, as mentioned in the posts above, these were a small minority of the LW force and the FB.VI met mostly the older slower opponents. Some FB.VI squadrons whose missions were mostly night ground attack and close to the front lines under allied air superiority, still used 130 octane fuel since they rarely met LW fighters at all.

The situation in DCS is that we have the 1943 performance Mosquito FB.VI facing in day light the 1944 190A8, and mostly the 1945 109K4 and 190D9, without the benefit of 150 octane fuel required for that.

The story with the speed of the bomber variants and the night fighters is a little different, but we don’t have them in DCS.

@Bozon Yeah you are totally right XVI was B so it was Bomber. Nevertheless my point still stands, Mosquito in DCS faces foes with much higher performance then it was in RL and this is why Mosquito isn't up to what is told about it.

I recall in clean config It's about on-par with DCS A-8 at SL (a tiny little bit slower or tiny little bit faster depending on whether Anton has a bomb rack on or not), but I suppose not many guys use Anton on MP servers?
