"What's important to note is that our/my participation and contributions to this forum are not always a reflection of the work that we are doing on our X-Plane projects or our attitude towards the X-Plane platform and community. Unfortunately the time that I have to contribute to any forum is very limited at the moment, and I'm sure there are members of P3D and MSFS forums that would like me to post more regularly, so this isn't specific to X-Plane.
We've spoken about this in other forum threads, our social media channels (Facebook etc), YouTube videos and other articles but let me clear things up here - we remain absolutely committed to the X-Plane market. Where we used to develop for FSX/P3D and X-Plane 11, we are now focused on MSFS and X-Plane 12. The success of MSFS has little bearing on our approach to X-Plane 12 as we continue to partner with the Thranda team for our X-Plane aircraft, and they have no involvement in our MSFS aircraft.
X-Plane 12 was released as an early-access product last year. Since then we've been working with Thranda to update our existing aircraft to provide X-Plane 12 compatibility, i.e. the same functionality as in X-Plane 11. Following it's exit from early-access, we've ramped up that work and have been rolling out the updates to our beta testers. We released the C152, DR400 and TB10/TB20 updates yesterday, and the PA28 Archer III, TX/LX and Duchess 76 are next up. The 146 is by far our most complex aircraft so naturally that will take longer and, like we've done with MSFS, we'd like to iron out any issues with the simpler aircraft first.
Hopefully that clears things up. Please link to this post if the same concerns are being raised elsewhere, and I'll try to visit here more often in the coming weeks and months.
Thanks,
Martyn - Just Flight"
