Why doesn't a Savage Cub need a mixture control?

Recommended Posts

The Savage Cub has a choke.

Probably has a turbo charged engine like the Rotax 914

Savage Cub has a Rotax 912 iSc engine which has an Electronic Engine Management Unit which controls the mixture ratio automatically.

If you look up this model aircraft it has been fitted with quite a number of different engines and configurations. The way Microsoft portrays it doesn't represent the thousands flying in the real world, of which may or may not be fitted with a mixture control. Some owners may live at higher altitudes or fly into high altitude airports therefore have a different engine option and installed a mixture control. 

Just like in the real world aircraft in the sim can be modified to various configurations as well.

Chokes on automobiles. Before carburetors had a temperature controlled spring valve to automatically change the mixture when starting a cold engine, all cars had a variable manual choke on the dash to choke off air intake manually. After engine heats up you push the choke all the way back in to disengage and restore a normal lean mixture. During operation you can choose to partially pull out the choke knob back out a little way to restrict air and enrich mixture.

In early days, all cars had a choke and a throttle knob on the dash. The throttle knob did the same thing as the gas pedal did except it stayed put when you removed your hand.

Pull the choke fully and partially pull the throttle and start the car. Walk back into your house and have a cup of coffee and toast. Walk back to the car, push both knobs back in and drive away with a warmed up engine.

You had to leave keys in ignition to do this, which meant neighborhood kids could go joyriding half way around the block and run then run away and you never knew which brat is was.

Is it bad to use automixture at high altitudes?
