OMG, I'm off in the TPM930 or whatever it's called, out of KRNO, beautiful!  I even lowered realism to FSX choice, and still it's just rocking side to side as if in extreme turbulence with no stabilizer of any kind.  Engaging the autopilot did settle much of anything down either, in fact I'm not sure it engaged as the button did not illuminate.  Flown FSX/P3D forever, but this thing is just bizarre!   It was the same w/ the Cessna 172 only less severe.  In a word, it's AWFUL to fly, which is a shame I'd love to actually fly and enjoy the scenery!  Any tips greatly appreciated!

Check the trim after turning off the AP, the AP seems to like to take over the trim and max it out.  More so when using AP+VS. Treat is like a kid and keep an eye on the Trim before / after engaging the AP and VS.

Change the flight model to Modern. Legacy i just bizarre.!

Noel, when you say "FSX choice" do you mean legacy mode? If so, I'm not sure the TBM even has a legacy flight model. I'd recommend using the Modern flight model and honestly since I know you're an experienced pilot with P3D, I'd set it to full realism (though I manually disabled crashes, engine damage and gyro drift since I'm lazy).

I've read some others saying the same thing about the TBM, which prompted me to take it up for a stability test...here were the results. Can you describe the differences between what you're seeing and what I saw here? Really interested in trying to understand this because there's a group of people arguing that the planes are just fine and another that are seeing really odd stability and controlability issues, and I've been tinkering with the flight models to try and understand the new parameters...

 

I would love that!  Ok I can try modern which I used w/ the Cessna in case there is something in particular wrong w/ legacy.  Yes legacy mode, FSX option.  Mine is a total, unequivocal joke, and a real bad one at that!  Clearly, something is vastly amiss, but I have no idea where to look at this point.  I doubt it's the controllers because I can stop giving any inputs and still, it's on a par with Huntington's Chorea, immediately after TO, after a lovely smooth taxi, and great looking performance and visuals.

Does the AP button light up when engaged?

Does the AP button light up when engaged?

There's a little vertical light next to the button that lights up. It is a little subtle. When you initially engage it, if you have no modes annunciated in the PFD, it will hold pitch and roll, then you can engage modes like HDG, NAV, VS, FLC, etc. 

Next to the AP button is the YD (Yaw Damper). That can be helpful with yaw stability, but I found the plane to be relatively stable even without it. In the real plane, the YD it turned on after takeoff as part of the clean up procedure and turned off on final approach as part of the pre-landing checks. So it is normal and expected that it would be on for the full flight.

Do you have rudder pedals?

Lastly, it is worth looking at your controller sensitivity. We had a long discussion about this in another thread and there's plenty of debate, but with a Saitek yoke that only has about 45 degree turn in each direction, I'd recommend the following settings:

Yoke Roll (X Axis) 5% dead zone, -50% sensitivity (calculated by taking the 'throw' or motion of your sim yoke (45) divided by the 'throw' or motion of the real yoke (90).

Yoke Pitch (Y Axis) 5% dead zone, -60% sensitivity (calculated in a similar way)

Rudder Yaw (Z?) Axis 5% dead zone, -30% sensitivity

^These are personal preference, and many of us agree that at low speed the control surface effectiveness is too strong, so the plane can perform a bit twitchy at landing speeds. That said, I've found the TBM and the 208 to be nice flying - you can check out some of the other videos to see what I'm seeing in terms of stability and control...

Nope, no rudder pedals always use auto-rudder in FSX/P3D, and even w/ the NGXu so for ground steering use my old Cessna trim wheel which is fabulous in that role.  I assumed since there was no auto-rudder setting, and that MSFS was eventually aimed at XBOX users, that it was essentially on by default w/ no way to turn it off.

I will look at my sensitivity settings on my yoke and report back.

I believe auto rudder is in the 'assists' menu somewhere. make sure you've got that on. it will be off with full realism.

Hey thanks for that.  I changed to those sensitivity settings and all seems fine now.  I really appreciate that fast help, and right on target.  The 'modern' FM seems fine too!

I'm not seeing any way to change the moving map range for the TPM 930.  Have you?

I was going to try to map all of the camera views I'm used to but I think there is so much control in this it will be worth learning a whole new set of controls.
