It is in the original post:

VERY IMPORTANT INFORMATION FOR OPERATIONS CENTER USERS:

We recently pushed an update for OC2 that you unfortunately have to trigger manually, otherwise OC2 will not be able to connect home to handle the 737 update, among other tasks. To update OC2, simply navigate to

 

C:\Users\<YOUR USERNAME>\AppData\Roaming\PMDG\PMDG Operations Center

Once you have this folder open, execute the program: 'OpsCenterUpdater.exe'

 

You should then be all set to run normally.

 

(This requirement was a design flaw in the OC2 that we have corrected effective with this update, so you won't have to do this again in the future, fortunately!)

I think there is also an additional thing you need to do.  That is, even though you have done the above and successfully got the Operations Centre to work again, I found that if you have a desktop shortcut to the PMDG Operations Centre this will still return the same error message. 

I deleted the original PMDG Ops Centre shortcut from my desktop, created a new one from the above folder location and the shortcut now works OK. 

I read on the PMDG forum this morning that some users are having the PMDG crash after the update, requiring a reinstall of  the 737.

The issue you describe seems to be related to a combination of ASOBO and PMDG.

You can change the following in any PMDG 737 aircraft for satisfactory results.

We have to take in consideration the following, in real life we don't exceed 5 KTS GS in turns more than  80-90 degrees. Of course, it can be done, but you will skid.

 

These are the changes: 

In flight_model.cfg section

 

[contact_points]

 

Change only value 78 to   50

point.0 = 1,  40.209974,  0.000000, -8.334975,  800, 0, 1.125, 78, 0.960516, 1.613, 0.6, 8, 7.5, 0, 485, 0, 5
 

to

point.0 = 1,  40.209974,  0.000000, -8.334975,  800, 0, 1.125, 50, 0.960516, 1.613, 0.6, 8, 7.5, 0, 485, 0, 5
 

Change

 

steering_time_constants= 3, 5
 

to

 

steering_time_constants= 10  
 

Add  

allow_stopped_steering = 1

 

In section [flight_tuning] change

 

yaw_gyro_stability   =2.80
 

to 

yaw_gyro_stability   = 0.15     

 

If you have a tiller or joystick, use these settings as a starting point for your assigned axis sensitivity.

thanks, out of interest have you done any mods to the Horizon 787 to make it taxi better ?

If it is the one from Flightsim, I will investigate and get back to you.

Just a few mods here in flight_model.cfg

 

[CONTACT_POINTS]

from

 point.0 = 1,    74.5,      0, -14.5,  750, 0, 1.33, 70, 0.22, 1.40, 0.90,  9, 11, 0, 270,  270,  1.5

 

to

from

 

steering_time_constants= 3, 5

 

to 

 

steering_time_constants= 40 

 

On this entry,

ground_crosswind_effect_zero_speed =-1000
 

they had -1000, the issue with that is that the real airplane will react during taxi and flight at above 5 KTS. For that reason, I suggest this entry

 

ground_crosswind_effect_zero_speed =8.43904929 //5 KTS X WIND
 

And under

[FLIGHT_TUNING]

 

 change 

yaw_gyro_stability =2

 to

yaw_gyro_stability =0.15

 

Here are some cockpit view settings that I remember that might be more realistic and helpful to you in camera.cfg

 

[CAMERADEFINITION.0]

 

from

InitialZoom =0.425

 

to

InitialZoom =0.525

 

from

InitialPbh= -14.766451, 0.009272, -0.053774
 

to

InitialPbh=-16.5, 0.009272, -0.053774

thanks ill give them a go

The installers and updaters are hosted on AWS servers. They will block requests in case there are too many requests from an IP range. PMDG support says it's not under their control and they cannot do anything about it. Wish I knew this before I had purchased their products. 

PS: using a VPN works for me but it takes hours to update.

It took me seconds to update.

OMG, thank you so much for those flight_model.cfg changes for the PMDG 737, LRBS! I have just tested them, and I can finally taxi my plane without it skidding every time that I try to turn. It negotiates even tight turns now, and it feels controllable at last Still not quite as good as the 737 NGX in P3D, but light years beyond the absolute mess of the release version.

I cannot understand why it was released like that. Surely the most important part of the ground handling model is to make the aircraft controllable? Who cares how accurate the numbers are if the end result is garbage?

Totally, i couldn't believe it myself when tried this. Congratz for the workaround to LRBS for sure. Now, it would be best if PMDG fix ground handling and all that comes with SU15 ground physics new parameters, I would imagine they started tweaking with this in the SU15 beta. Lets hope. Oh and I have already posted this in PMDG forums BTW https://forum.pmdg.com/forum/main-forum/pmdg-737-for-msfs/general-discussion-no-support/284102-issues-with-sim-update-15
