Hello everyone, does anyone know of any add-ons or software that can record all the data from these “study-level aircraft”? I enjoy being able to review how I landed such aircraft, and I currently use SkyDolly. However, it only records the data that is native to the default MSFS and not the external systems that come with these aircraft. Unfortunately, when I play back the recording from the FBW (FlyByWire) aircraft, the flaps are missing and the avionics are not displayed correctly. I would appreciate any suggestions you may have. Thank you, and I hope you all have a nice day.
may be a lead … 
the only thing i can think of is TacView, but i dont know if msfs is supported
edit: add link: Tacview - The Universal Flight Data Analysis Tool
It is and it’s what i would recommend for whatever that’s worth.
2nd this. If replays are important to you, this is worth the money. A bit of a janky learning curve but it’s relatively easy to use once you figure it out.
A Lot better than the developer mode replay or freeware options
I’ve used Flight Recorder for a couple of years ago. Besides performing replays at different speeds, it can export a CSV file that can be imported into Excel to analyze the data. It is possible to position the replay at any point of the recorded flight, replay at various speeds, or stop the replay to view the frame. I haven’t had any issues with Flight Recorder but I haven’t used this with non-stock aircraft.
The only anomaly I’ve found is that Flight Recorder only captures aircraft frame information during flight. It doesn’t record anything external to the aircraft. For example, it doesn’t record any ATC communications, external traffic, or weather. For example, when recording an approach and landing, during replay the ATC communications will probably be much different. One “feature” I use a lot is the ability to stop the replay and then take over the flight from that point. If I botch a landing, I can stop the replay and reposition the aircraft to the start position of the recorded flight to try the landing again.
NOTE: this Flight Recorder does not have any video recording feature. Use your favorite video capture app for video replay outside of MSFS.
I use this primarily to replay a portion of the flight, usually the landing, several times changing the camera view during each replay for video recording. After exiting MSFS I edit these videos together to show one flight with different views in sequence.
