Anyone experiencing ground steering probs? I'm using rudder input and all other DC modules work fine except for the Mig.. Looked for a nose wheel option but could not find one.

Tks much

IIRC, this aircraft has a free castoring nose wheel. That is to say there is no nose wheel steering. You need to use differential braking, but there are no individual toe brakes. You have to deflect the rudders then pull the brake lever to do the differential braking.


The world is going mad. Me? I'm doing fine!

Have you done the taxiing training mission? The Mig-21 is actually very easy to taxi, but it does have some nuances that you need to get your head around.

The key thing is that there's a switch that needs to be flipped between Navig and Landing dependent on whether you're taxiing (Navig) or taking off / landing (Landing).

You also need to be aware of the single joystick-positioned wheelbrake lever and the limited supply of compressed air for actuating the brakes.

It also helps to keep your taxi speed up a little. If I taxi a bit fast, the plane is easier to steer.

Steering is accomplished by differential braking of the main landing gear. The nose wheel is free-castering. The nosewheel brake level determines whether the front wheel participates in braking or not when the brake lever is compressed. For high speed operation such as takeoff or landing, use 3 wheels for braking (nose wheel braking on). For low speed operation where maximum braking is not required and turning is needed use 2 wheels for braking (nose wheel braking off).

The proceed/landing/nav switch is for RBSN navigation only and has nothing to do with physical steering or controls.

The differential steering partitions pneumatic pressure based on pedal input. This takes a little time so it's easy to over steer. Also if you partially activate the brakes there is more brake pressure to develop a difference and tighter turns are possible. But suitable steering is possible with the brake lever completely open (off).

To start moving, set the Nose Brake Lever to the Vertical Position (OFF), move the throttle (Needle #1 on the gauge) to just over 80%, once you are moving, deflect the rudder and as soon as you have control over steering , bring the throttle back to 60% and leave it there while taxing, when you want to stop, bring the throttle back to ground idle (approx 40%) and apply the brakes. If you need to make a sharper turn than normal, advance the throttle to 80% and apply the brakes and deflect the rudder in the direction of the turn, bring throttle back to 60% when done the turn.

This works for me and right now I have ZERO problems moving around with the Mig 21.
