If you want more realism in x-wind landing touch down, sing-eng taxi, this is the tweak to use....if you don't like it don't use it.

So just so I am very clear if we have the DynamicFriction.lua all set up properly is this line in the fsuipc.ini, "patchsim1friction=Yes" still needed?

No.

Those of you who don't want to mess with the rolling friction at all, but still want to have a better sliding friction: You can also just modify the Frictions.lua out of the Lua_Plugins_07July.zip and just keep the SLIDING-values in it. This is what I'm doing now.

We did not code the aircraft to use any friction hacks. If you mess with that you're potentially going to see things that don't behave the way we intended as far as braking, takeoff distance etc.

Ryan,

 

In all seriousness this is not a hack, it's a correction to FSX ground friction via FSUIPC. Perhaps before tweaking the ground model in the 747XV2 to take account of the excessive friction that FSX models, PMDG might take a look at incorporating what is in effect a patch to FSX as part of your simulation.  You might find you need a lot less tweaking of brakes, thrust, etc to get accurate taxiing and runway performance

 

It's far better and more convenient to the user to have the correction for ground friction in one place (FSUIPC) than for each developer to make their own tweaks (or not).  You use FSUIPC for other things, why not this?

 

Anyone with the current FSUIPC4 version can enable this friction adjustment in the FSUIPC.ini file.  It's a one line text change.  The LUA files enable more dynamic fine tuning for those with the registered version.

For the last time the dynamicfriction.lua does not change any core files, it patches in memory through FSUIPC dynamically, remove the lua file from the modules folder and its as if it was never there.

 

Which is the very definition of a "hack" as I used the term. Call it a memory patch or whatever you want - it's hacking and changing the way the sim works by default. We are not going to require that users install FSUIPC and use this in order for our product to work. End of story.

 You use FSUIPC for other things, why not this?

 

We do not. FSUIPC is not required in any way for any of our FSX products.
