Okay, I think I know what’s going on here. Seeing as you tested with jets and airliners and they do work just fine. But you have a problem with prop airplanes. What’s the difference between jet airliners and Prop GA? Mixture…
My theory here is that the X-52 isn’t bound to a mixture control. So even if you push the throttle to 100%. If the engine is not getting enough mixture of fuel and oxygen, the engines can’t push to 100% power.
Ideally, if you have other throttle that’s designed for GA, like the Logitech G Flight Throttle Quadrant, most people will bind the black lever to throttle, and the blue/red lever to mixture. So when you want to add power you also need to add more mixture. But I’m not a GA flight simmer, so I don’t know how to fly a GA myself. Someone else more knowledgeable may correct me if I’m wrong.
One thing to know as a thumb rule is that. Just because a hardware is more expensive. Doesn’t mean it’s better out of the box. That’s just not how flight simming works. You need to do a bit of homework to setup your hardware properly, no matter how expensive or how cheap it is, you have to set them up first. The default profile is there as a guideline. But eventually, you have to set them up yourself the way you want it to.
So, I think the X-52 is either not have Mixture Axis bound by default, or something is wrong in the default binding. My suggestion is to spend a bit more time creating your own control profile and make sure the bindings are correct.
One thing I noticed from your video is that you spent most of your time testing from the exterior and looking at the HUD. This can help to tell you the final result of the behaviour, but it doesn’t tell you the full information to do a proper trouble shooting. Instead, try to stay in the cockpit, and just start cold and dark first. When you want to test throttle control, try to move your throttle in your X-52 and have a look at what’s happening inside the cockpit. Does the throttle lever move the same way as your input? Does there any other movement inside the cockpit that you expect/unexpected? Does the mixture lever moves the same way as your input? It’s these things that you need to do first to determine whether the problem is coming from your hardware, or MSFS interpretation of the signal coming from your hardware, or even the aircraft itself is the problem.
Then, once you think cold and dark cockpit movement is fine, try to start it up, see if it’s behaving the way you expect it to, and slowly continuing through more phases in the flight. Another thing, the external HUD doesn’t tell you the entire picture. They’re there just as a basic reference. The full behaviour is happening inside the cockpit. So instead of staying outside wondering what’s going on. Just jump into the cockpit and look through all your instruments, look for something that’s out of the ordinary, is there any error message showing, any warning, the instruments in the cockpit tells you more information than the basic external HUD.
Another rule to live by is “You cannot use the same profile for all airplanes”. Basically, there’s no such thing as a single default/custom profile that would work for “all aircraft”. This is because different aircraft has different rules to them, different behaviour, different flight mechanism, and requires different skills. So you can’t have one profile that would work for all aircraft, because those aircraft will interpret different inputs differently.
Instead, you need to create custom profiles for each type of aircraft. For example, I have an Airbus control profile that I use for FBW A32NX, and Headwind A330-900neo. This one I have it set to Gear Up and Gear down into a single button in my TCA Airbus quadrant. Then I also fly the PMDG 737. In that one, I can’t use the same Airbus control profile, because the Boeing doesn’t interpret Gear Up and Gear down the same way as an Airbus do. So I have to create a separate Boeing profile, with the landing gear bound to Toggle Landing Gear command to the same button. But now I have to use the lever differently than I do with the Airbus.
This is just one example. I had a lot more differences in my control profile for these different types of aircraft. I also have the Indiafoxtecho F-35, where I have a separate control profile for them because I have to bind the Afterburner button somewhere since Airbus and Boeing doesn’t have afterburner.
Do you see where I’m getting at here? Also, hotswapping hardware in the middle of the flight is not recommended either.
If you don’t know how the mixture is suppose to work in a prop GA or if you don’t want to bother with it, try to enable the Auto-Mixture assist in your assistance options. See if that makes a difference.
