Li-2 mixture controls

It would appear that the mixture control key strokes are animating the carburettor heat controls to the right of the pedestal rather than the mixture levers on it. Other than that, very nice.

The fuel mixture controls on the Li-2 are in a different position than the carb heat levers.

Well you learn something every day. Hideg = cold, meleg = warm, so the carb heat levers on the Li-2 are where the mixture levers are on the C-47.?

Hi Guys, I tested this nice aircraft and wasn't satisfied...problems with overheating engines during take-off and very poor flight characteristics...

 

So...the problem is only in mixture lever settings, look at this picture: https://photos.app.goo.gl/cfm4KihvbUBjycqn6

 

Down position is marked in Russian language "BOGATAJA" so RICH! But game shows you engine mixture 0%!!! and top position is "BEDNAJA" = LEAN and game shows 100%...that's only problem.

Notes about mixture settings in manual is confusing too...

Engine mixture control is automatic when the mixture lever is set to maximum. It is possible to manually lean the mixture by moving the mixture control to less than maximum. This also reduces fuel consumption during flight.

 Recommended mixture control lever positions for various flight modes:
- When running the engine at low throttle near the ground, the mixture control lever should be in the position of about 60%
- When the engine is running at full throttle near the ground, the mixture control lever should be in the 40-50% position.
- As you gain altitude, the altitude corrector closes.

 

 

After 2 days testing everything works and Li-2 is nice and very useful aircraft, not so powerful as C-47 because engines M-62IR are not so powerful as Wright Cyclone R-1830-92 but still good.

 

How to:

IMPORTANT: take up to 50% fuel in cargo loadout to not exceed the maximum takeoff weight.

- for start engines and take-off set mixture to 0% (down position) = FULL RICH. Fully open both coolers after engines start-up (radiator and cowl flaps)

- set take-off power max 2200rpm/1050 and max for 5 minutes but recommend you only for necessary time for take-off and gaining some altitude, then use nominal power 2100rpm/900 and you can set mixture to 40-50%...40 is better because richer mixture better cooling so lower engine temperature

- initial climb speed is only 4m/s, then 2,5m/s so fly gently

- for cruising use 2000rpm/640 and mixture 60%, radiators as required, too low temp on cylinder head and oil is not good (there are oil temp gauges for incoming oil temperature - in front of flight officer and oil outlet temperature - in the middle of instrument panel and bottom row - that temp is important for you and normal value is 115deg.C/max 125, standard gauges for cylinder head temp are on the right side and 205deg.C is normal and 235max)

- for landing I use mixture settings 40-50%

 

Good luck guys. Salute

Meleg means hot or warm,  not cold.

You're quite right, that'll teach me to read my replies before I post!!😁
