PMDG 777 front wheel not turning sufficient

Recommended Posts

P3Dv4.4
FSUIPC 5.15
PMDG 777

Can't seem to configure my Saitek pedals correct through "send direct to FSUIPC Calibration" along with PMDG 777.
Brakes and rudder works fine, but the front wheel works poorly, which means that I have to use my throttles violently as a compensation in order to make sharp turns.

For my Saitek pedals ONLY I previously through the years used to send my Axis to "FS as normal axis" (rest of the "joysticks" direct to FSUIPC) which worked fine until FSUIPC/P3Dv4.3. From then on my other "joystick", my yoke, went totally bananas and out of control! No surprise here, as according to the manual, one is not supposed to mix  "send direct to FSUIPC Calibration" and  "FS as normal axis"...anyway this worked for a long time, until now when I don't seem to have no other choice than let all my axis on all my "joysticks" assign to  "send direct to FSUIPC Calibration", which in practise wont work for my pedals!

What is going wrong here?
Would it perhaps help if I instead use "Send to FSUIPC Offset" ONLY for my pedals mixed with "send direct to FSUIPC Calibration" for the rest of the "joysticks"..?

Cheers,
Morten

Hi Morten,

what did you see this? Its fine to send one axis to "send direct to FSUIPC Calibration"  and another to "FS as normal axis". Of course, each axis itself can only have one destination.

Can you also check that you have the controllers in P3D disabled (maybe they became active again after your P3D update?).

There is no “front wheel” control used in FSUIPC. You may be able to use the FS control “STEERING SET” which I think was new to one of the releases of P3D and so never used by FSUIPC in its controls. Steering on the ground has always been by rudder operation, hence the blending between the steering tiller operation and the rudder.

“Sharp turns” in a PMDG 777, or really any airliner, need low speeds, and judicious use of differential braking and, yes, occasionally asymmetric thrust (as the aircraft slows even more during the turn). I don't fly PMDG aircraft, but maybe some other PMDG users could help you out here.
 
I'm actually surprised that using “send direct to FSUIPC calibration” on any PMDG Boeing airliner works at all. Those tend to read the control values themselves direct from Simconnect, whilst FSUIPC is calibrating them and sending (possibly different) values at a much lower Simconnect priority level (to avoid an infinite loop). This generally give unwanted jerkiness.
 
Cheers,

Also, please see this thread (originally for FSLabs A320) for a general discussion on steering using the tiller/steering axis rather than rudder:

Hi John

Thanks for your profound suggestions...
Now I totally erased axis for my pedals inside the FSUIPC.ini  and instead established axes directly inside the P3Dv4 controls environment. So far steering is back to normal again.

Cheers,
Morten

Assigning in FSUIPC to FS controls is effectively identical to assigning in P3D. The exact same controls are sent to the sim. Only the dedicated "direct to FSUIPC calibration" controls are processed differently.

The P3D steering axis control is also assignable in FSUIPC.

I guess, you're right and the problem is still present - probably just me getting more and more use to compensate the lack of turning by using cross throttling...

I read the "FSLabs A320 Steering/Tiller debate" link which John provided me. However I'm afraid it got too nerdy for me and didn't really catch the conclusion, if any.
Please bare over with me, I'm just a regular user and have no skills whatsoever into programming and special FSUIPC mods.

So in simple terms, please;
1. Is there actually a way to mix the tiller facility with my (physical) pedal rudder axis assignment?
2. If so, would I actually benefit with such a mix in order to make my front wheel turning more efficient?

(During turns on the taxiway I notice that the animated tiller on the PMDG 777-200 actually DO turn - whether this animation is actually a valid reflection of a tiller process taking place for real I can't tell)

Cheers,
Morten

FSUIPC can blend input from a tiller axis with that from the rudder pedals, but of course this blending only applies if you have a separate axis for the tiller. It is blending the inputs to give more control to the tiller at low ground speeds, more to the rudder pedals as GS increases. Both are using the rudder axis. By calibrating them separately give can have a more gentle rudder control in the central areas, whilst the tiller is more proportional to the tiller position.
 
With a separate tiller you can either use that facility, or, with P3d now, assign to the Steering axis control instead. That might give more “nose wheel” action, but I doubt it will be more than the rudder gives.
 
Without a separate tiller axis you can’t really do much. You could try assigning the one rudder input to both rudder and steering axes -- FSUIPC allows for multiple axis assignments (up to 4), but I don't know what the results would be like. There's no blending because they are going to different functions in P3D.

Ok thanks, I'll get it a try.
What is noticeable though, at least in my case, is that this lack of steering came about after updating from P3Dv.4.3 to v.4.4 - might be a random event, might not be...

Moreover, according to this my previous statement and the following discussion, I've chosen as an experiment to completely keep my pedals out from FSUIPC. Which means that my pedals currently is calibrated within the P3D settings environment only, whereas my throutles and yoke is still calibrated inside the FSUIPC environment and send "direct to FSUIPC".
With this combination I unfortunately still find my yoke going completely bananas and uncontrollable. It will happen mostly during an ILS approach, if I then choose to abort the autolanding and disconnect the autopilot in order to make a visual approach instead, then the yoke will turn all the way to the right and become totally out of control! The only way I can overcome this is by replugging the yoke into the USB slot and from then on it will be controllable again.
All together, for some reason quite a mess here these days...?!

Unfortunately it isn't a good idea to mix like that, as P3D may decide to auto-assign the other axes. Choose one or the other otherwise you are likely to get conflicts.

The best way to use the FS controls is to assign to FS controls in FSUIPC. They do exactly what the P3D ones would except for allowing P3D to read the axes directly.

Okay Pete, got it! 
In fact my 'some what' common sense already told me before I even started this configuration!..hi, hi...life aint easy.
The steering issue however, is left to solve - not for common sense to solve.. quite a drag...!!

I tried to mix tiller and rudder, assigning both to the pedals through "Send direct to FSUIPC Calibration". Not an option, at least not to my PMDG 777-200. The tiller mix reacted by turning the wheel all the way to each side. Not possible to go straight forward. 

I found the best solution till now, by assigning the axis rudder (no tiller mix) to my pedals and use "Send direct to FS as normal axis". This makes my front wheel turn fully perfect again as it use to couple a month ago!

However my yoke, which is assigned trough "Send direct to FSUIPC Calibration", still go bananas if I choose to turn off the autopilot, as described above.
No axis whatsoever, is no longer assigned inside P3D - Options - Axis Assignments. So what the heck is going on here?

Don't just delete assignments in P3D. Tell it not to use any controllers -- a check box in the last option in P3D's Controls Assignments menu.

And test with a default aircraft. Some add-ons do not like FSUIPC's calibration because it results in it sending controls to P3D at a different SimConnect priority.

My dear Pete

This was indeed your best advice of the year!!!!!!!

EVERYTHING now works as expected, yoke, throttles and pedals! Wow! 😃
