LaGG-3 Series 4 Water Radiator Handle

[TimSell75]

Can somebody tell me where the water raditor handle/Wheel in the LaGG-3 Series 4 is placed in the cockpit? I can open and close it, but there is no nothing moving in the cockpit? 🤔

It's controlled by pushbuttons.

Thanks a lot. But there is no animation for it right? How do I know how much the radiator is open when there is no gauge or lever?

[LukeFF]

There is an animation for it yes, but it's kind of by feel to find out how far it's opened or closed.

The radiator temp is your gauge.  I'm not trying to take the piss... if its at or above max temps, your radiator is likely closed. When it is well below max temps, your radiator is likely wide open.

Thanks! I already thought so. Kind of weird though

Not really weird.  The actual angle/percent of opening  of the radiator shutter isn't important.  The operating temperature of the engine is what's important.

So just open or close to obtain the desired indicated temperature.

There is an animation for the outiside view of the radiator opening and closing but the animation in the cockpit seems to be missing

It's there. 🙂 You just have to watch closely for it.
