I'm sorry but hes right. Don't convince me that out of the box integration in 5 ACF is worth it 50USD. You don't touch in others peoples work and you know it you just simple put a custom 3D panel on top of their avionics just like the rxp gtn 750.
Maybe if you guys want that approach maybe you should lower the price then. Have you thinked why others avionics have a enormous compatibility and yours don't its not worth it for devs to integrate price related maybe. Hey but its just my opinion
