LA5 tachometer reset issue

[adler_1]

my tachometer is stuck and has no response to throttle , how do i reset it ? 

[RedKestrel]

The La-5 has an RPM lever to control engine speed via the constant speed propeller unit, you need to manually increase that to get higher RPM, and move throttle to increase manifold pressure. However, even increasing throttle a susbtantial amount should also move the tachometer RPM a little bit even if the RPM is set low.

If you adjust the RPM/Prop pitch do you see the lever move in cockpit?

[adler_1]

yes i do , but only the long arm , the short stays put . I take off with 100% prop pitch and reduce to around 82 in cruise , i also reduce slightly the mix . Also the accelerator % is not indicating when i am in combat or cruise , so since my RPM isn't working i'm guessing cruise is around 62 % and watch the speed and temp gauge . The short arm is stuck slightly above 2000 RPM and wont budge

I didn't mean arms on the tachometer, I meant the physical lever that controls the RPM setting in the cockpit. Look to the left and use whatever key or axis you have bound to increase/decrease RPM and see if that causes a lever to move on the throttle quadrant in the cockpit.

 

I think the prop pitch keybinding is different than the increase/decrease RPM binding. The prop pitch keybinding is for manually adjusting the pitch of the propeller like on the 109 in manual mode, the increase/decrease RPM keybinding is for adjusting the RPM lever that controls the governor on constant speed propeller planes

If you could post a screenshot of your keybindings it might be easier to explain.

yes the lever below the throttle quadrant moves correctly , its bound by key to my slider on the joystick . This is my RPM regulator . correct ?

Around 1 min into this video Requiem goes into the various components of the throttle quadrant. I think that is correct if I'm understanding.

Maybe the lever isn't moving the full way? When you test the slider axis in the key binding can you move it from 0 to 100%

I haven't flown the La-5 in a long time so I'm not an expert on it at all.

i have seen this video and i noted he never talks about the RPM or what is the rpm limit for cruise or combat . that's why i'm asking questions . I learnt a lot from the sheriff videos 1 and 2  about cooling but again he too never goes into the RPM and ATA . So in the meantime i'm doing my trial and errors while getting killed .

That's because the La-5, like the Yak-1, can be run at max RPM (2400 RPM) for an unlimited amount of time. You really should have a look at the tech specs in-game. 

You can fly the plane at 100% throttle (950mm Hg Manifold Pressure), 100% RPM (2400) for the whole flight. The only limit is five minutes for the boost, engaged with the boost button, which brings the manifold pressure to 1140mm. And with the La-5F modification, the boost time is unlimited, basically all you have to worry about is fuel.
 

Mixture at 100% is the automatic setting for the La-5.

 

The only reason to reduce your engine settings is for fuel economy. 

Probably the minimum RPM for the La-5 when above idle throttle is actually pretty close to 2000 RPM.

if i do what you just mentioned above the engine will seize as soon as i reach the airfield limits on take off . One of my struggles is continuously having to adjust cooling such as radiator , inlet and outlet flaps  , rpm and throttle , its too much ,when in action if you are not gazing at your gauges the engine will seize within minutes of engaging . I cannot believe in reality it was that bad during the conflict . This model came out well after they were mauled by the German planes at the onset of the conflict .

You don‘t have to. Inlet flaps are opnen in flight, unless you‘d mak a long, fast dive at idle throttle. Outlet flaps are usually kept closed in flight unless you fly slow at high power. The oil cooler you can leave at 50%. There is not much to do, actually. If you blow the La‘s engine, you have inlet flaps in a position other than full open.

Oh yes, it was. This is why some went great lenght to install a Kommandogerät that takes care of most. Sure, there were some victims that found their lot of having to pull levers etc all the time to be an advantage, as they thought it gave them more options. Like accellerating faster when just increasing prop pitch and then giving full power (there is only one left hand). Is like when she says „But deep down, he loves me!“.

 

Some aircraft can indeed be entertaining by just flying them.

what about RPM is 80 % correct ? leave mixture full 100% always ?

I leave rpm at 100% with the Russki planes for gaming. Some, like the Yak don't mind going a tad lower than that, but I don't care. It is only an issue if fuel is running out. Then you go down on rpm and mixture. That helps a lot in terms of mileage. I reduce mixture always just below the smoking point. Plenty power, acceptable heat, less visibility. My mix-o-meter is the rear view mirror (or my owl neck).

ok will try all that , no wonder i could not keep up with an ME110 , thanks advice

Full RPM, Full open Inlets, full open oil, outlets opned as far as needed as much closed as possible, Full Mixture (which is auto rich)
and the throttle and additional boost as disired.

With that setting the La-5 does not overheat, runs like a charm and is nice and fast on the deck. And the needed engine control is minimized too

Der Sheriff -Zacharias .

just tried it out as per Zacharias recommendations oil 40 % and it was fantastic , temperature way below 100 and never went up even accelerating above 80% , at 50 % throttle i was at nearly 500 KPH  , rpm 2400 .  Thank you for  the much needed advice . By the way Sheriff i always watch your vids when flying new aircraft .

the Boost

At what altitude do i use the boost ?
