Hello,

                        I'm basically new to the PMDG 777-300, I was wondering how to get the plane to steer. I have no pedals, I use thrustmaster joystick as my tiller. The rudder does move, but the nose gear does not. 

I have been watching many tutorials but haven't yet been able to find any relating to steering. Can someone help me on this, I will appreciated very much. Thanks

There's a option in the FMC settings that connects the rudder with the nosewheel, have a look.

Yes, thanks.

Its Hard to turn wonder why.......

how fast your  taxing  might be  the  answer

To be fair, the ground handling in MSFS leaves a LOT to be desired. That may be different now with the new ground physics, but most developers still have to implement this in their products. My PMDG 737-600 was absolutely uncontrollable until LRBS very kindly suggested some changes in the config file. Now I can turn it on the ground in a similar manner to the P3D version. I do not have experience of the 777 in MSFS, so I do not know if it has the same kind of problem as the 737.

And dont be to fast with your speed at ground, you know it is a heavy airliner..

cheers 😉

This. I don't have the B736, but the B737 is a nightmare to turn, awful ground physics. You are forced to perform standard 90° turns at 3 knots otherwise it understeers into the grass. Funny enough on the other side the B738 is much much better

I wish that I could find the post that LRBS made describing the changes that need to be made. The difference in handling is like the difference between light and dark. In short, I couldn't care less whether the ground handling equations that are being used are identical to the real thing if the end result is a complete mess. I just want to be able to control the plane.

A 777 Retired American Airlines Captain with over 20,000 hours, did a video of the 777, and said the taxiing behavior was very realistic. 

That is good to know, because the F or LR are targets for my credit card.

There you go, Jeeno. Make the changes suggested by LRBS, and your ground handling problems with the 737 will be over.

I've never noticed the 777 being hard to turn like the 737 was. The T7 is fine in stock setup

I use the same controller settings for all 737, 738 and 739. I use an "extremity dead zone" on the tiller (joystick z axis) and find my full tiller deflection setting works well in the 38 and 39, but in the 737 if I use full tiller deflection it under-steers and if I de-rotate the tiller just a little bit the nose wheel angle is much greater allowing very tight turns. In other words I will probably create a 737 specific profile with the joystick z axis "extremity dead zone" a bit higher (greater + number).

When you are taxiing the 736 or 737 in a tight turn try reducing your tiller input bit-by-bit until you notice a sudden tightening of the turn - then go to your tiller sensitivity settings and set "extremity dead zone" a bit higher.

Maybe the same thing happens on the 777 and an "extremity dead zone" setting might cure it.
