Level flight speed

[Convoy]

Can't seem to get more than 230-250 kts out of the thing in level flight. Anyone else? 

[Dogsbd]

Same

[Super Wabbit]

Clean config with 50% fuel, +25C, and no wind, I was able to get the following:

268 kts @ 277 ft rated power (max cont)
307 kts @ 311 ft full power

 

(edited to add weather conditions)

Same here.

i wouldn’t balk at being 10 kts off but am about 70 kts off of speeds listed when following the engine settings as published.

People complaining about airspeeds need to post their flight conditions, engine settings, configuration and especially altitude. 

Clean, 15ºC at sea level, cowl flaps slightly open and military power (2700 rpm, auto rich), I’m consistently showing 302-5 kts.

Could the differences people are complaining about might be due to IAS vs TAS at higher altitude? Make sure you are getting 2700 rpm and maximum manifold pressure. Also, I had to change the prop governor axis to “slider” to get it to work properly.

As mentioned, there's a whole bunch of variables that affect the indicated airspeed, including:

• Power settings, e.g. throttle, prop, mixture, using water, supercharging setting
• Altitude/temp and the resultant density of the air
• Drag from configuration, e.g. weapon loadings, canopy open/closed, opening of cooling vents etc, trim

[Firebugs]

I posted this in the bug report section but try again without ever loading HVARs on the wings.  With HVAR pylons (rockets fired) I get 240-250kts max, with a slick plane 290-300.

 

If I had to guess I'd say a drag value is way off for the HVAR pylons, but that's pure speculation. 

 

Edit: also cowl flaps make a pretty big difference for speed if you're trying to get the very last little bit out of it.

Tried a mission on Marianas doesn’t seem as though you can set temp lower than 20degrees 

after flying Saipan to Guam started to fly home got to 20000 ft set everything up as everyone has recommended but got 250-260 kts. Obviously I understand altitude has an impact on TAS. However got my wingman to rtb and he just accelerated away from me.

so I guess I’m doing something wrong somewhere. 
 

overall though I have to say I am loving this module and loving flying over the PTO in WW2 scenarios. It looks stunning.

you must control rpm gorvener by mouse for for full power, not axis or keyboard max rpm 2700 to 3500 / max manifolder gauge 54 to 75 (WEP)

Difficult to see in this video so your saying your axis is not able to take your RPM to maximum?

I now see exactly what you mean, just tried it and yes got over 300kts level flight. I tried mapping a button instead of an axis to increase to maximum RPM but that doesn't work seems as though only the mouse increases your RPM to maximum, 

Throttle axis seems fine though. 

[felixx75]

Of course, the question arises as to why you want 3000+ RPM...

TO, Mil. Power and WEP are all specified with 2700 RPM.

Try changing the propellor governor to “slider” under the tuning menu using the checkbox. That should allow engine rpm to function normally.

Ah ok thanks for the advice shall try that when I’m next on DCS.

As discussed in Thunderbolt section of the forum, R-2800 could take revving up to 3050-3060 shortly and even its latest versions could do it somewhat safely up to half a minute.

If it's possible to use mouse to get up to Napier Sabre levels of RPM in our Corsair, that's more of a hilarious bug than a "feature" showing how WIP the current engine code still is.

Reminds me of a glitch I was exploiting in Aces of the Pacific, which made P-40E the fastest plane of the war by far .

Enjoy it while it's not fixed yet .

You can physically see the RPM lever move 2-3 more inches down, so if it’s a glitch it’s also been graphically modelled as well. 
 

also there the smoke that trails from the airplane once the RPM lever drops further as well.

Not for me. I have bound it to a lever (Axis) and the lowest position I reach with the axis is the same position I reach with the mouse. Just tested a few minutes ago

When I’m next on my PC I shall look at the figures I get for RPM. I don’t remember what they were. What I do know is I’ve gone from level flight of 260 kts to 320 kts since discovering this. 320 is more like the published level speed of the Corsair.

When you do external view can you see a faint trail of black smoke when you have your axis set to maximum? 
What is presume is the water injection.

The RPM lever (and the position of the lever) has nothing to do with the Water Injection.

Well all I know is since discovering this where the rpm lever is now dropping lower for me I can undoubtedly see a trail of faint black smoke from the airplane. Similar to the smoke trail from a F4 and B52. 
Maybe that’s also combined with having maximum throttle setting as well. Also it does explain why my speed went from 260kts to 320kts.
Also when this RPM lever drops it also affects the distance the cowl flaps open.
When we get some kind of confirmation from the devs then I guess it will all make sense.

You are right that you reach about 3100 rpm when you pull the lever down with the mouse. The physical position is the same (at least for me), but the rpm goes up and then you actually see smoke, which I would rather explain as pure stress on the engine. But of course I don't know that either...

Well hopefully we can get some confirmation soon.
