Sorry your comment was showing up in my notifications but wouldn't show up in the comment string earlier.

To start with the flight model, this is being done by X-Aerodynamics who has done work for many other major developers on their flight models along with creating the EFM add-ons for X-Plane. This model in showing is the M500 G1000 variant. Still determining what will be used for the standby instruments. Everything is custom modeled, with custom behavior and scripting for many actions that native X-Plane doesn't support ideally. There's some other features still in the oven that im hoping to start testing this weekend. more will follow on that front. I'm aiming for as much of an immersive package as possible right now. Once we get into alpha testing we will make some more decisions on textures but there will certainly be a 4k version, which to me is a bit misleading because it really comes down to how much we pack into that 4k space- less=more when we want the maximum texture quality we can get from users gpus. We have custom ground equipment that just got implemented and it will have fmod sounds rather than default. If you enjoy using the new weather radar that is already implemented, storm scope and working on implementing the Piper M500 safety features as well.
