I´ve noticed a very strange balance movement linked to the Mig-21 gear suspension-brakes-thrust.

 

When i hit the brake system and at the same time i add thrust the gear suspension moves to a equilibrium point, wings parallel to the ground, but when i set the throttle to idle and release the brake, the Mig start to fall to one side loosing this equilibrium, to one side or the other.

 

A couple of pics showing this strange lateral movement.

The worst problem is when rolling, the Mig wants to turn to the falling wing side making harder to roll and taxing it. You must made constant corrections with rudders and brake system.

 

The same when taking off or landing. At high speed, this effect is not noticiable, but a lower speeds one wing starts falling to one side because de suspension system and starting to drift to one side.

 

Is this intended?

 

Maybe a suspension bug?

Anyone could make this test to confirm t please?

 

It´s easy.

 

Press brake, add power and see how the Mig-21 gets wing straight relative to the floor.

 

Release brake, throttle idle and one wing fall unbalancing the wings to one side.

Oh wow, so this really is a thing. While sitting on the ground or taxiing I've kept wondering to myself if the plane is actually level or I somehow broke something with the gear. At first I thought I was just going crazy or maybe my TrackIR wasn't working right but I can confirm I've seen this behavior as well.

It's your fuel loading. Once you're down to ~30% in the tanks, it's the most exaggerated.

 

Load up on a tarmac at Batumi with ~10% and a clean configuration. Start up and taxi around the ramp while in observing your suspension from the exterior. You'll notice the aircraft exhibits a slight lean. Then stop and add in 20%. Once you do that, start taxiing again and you will notice that the lean is much more pronounced in turns.

 

Keep adding in small ~10-20% increments of fuel and you will notice it becomes less and less pronounced as the increased fuel load weighs down the main gear suspension.

Reformers hate him! This one weird trick found by a bush pilot will make gunfighter obsessed old farts angry at your multi-role carrier deck line up!

Anyone notice the landing gear being extremely bouncy on landing. I'm touching down fairly softly ( I think), but I can't get it to stop bouncing back and forth a bit . Not sure if related

And this lean related to fuel quantity is real?

 

It´s very hard to taxi straight forward with this unbalancing suspension.
