Mixture and Mouse Control Help

[Roblex]

Yes it is normal. There is a mechanical linkage that means you cannot change to 'Lean' unless you have reduced the throttle and there are no intermediate stages.

There is rarely any need to adjust the mixture. The default setting is correct for take-off, climb, cruise, combat & landing. The only time you might want to adjust the mixture is if you are a long way from home with low fuel, which is rare on this map. If you really must play with it then reduce your revs right back to around 2200 or lower using the prop pitch and a boost setting down below 3 but if you try going full throttle again on Lean you could damage the engine.
