One of the many reviews from the TDS GTNXi 650/750 software for in MSFS. It’s paid software, more information about it here. And even active on Discord. And you could also use it on this hardware item of RealSimGear. (It’s on my bucketlist 😉 ) Below a short introduction/review. If you have any experience with it, please let me know in the comments. The software is also compatible with the A2A Comanche 250.
