We were just informed that the Bell 429 for FS9 is the project of Sergio Kauffman who asked George Arana, from Eagle Rotorcraft Simulations for help on the FSX conversion.
Tom Woods, also not affiliated with ERS is working on the X-Plane version as well as the liveries for all the 3 versions.
ERS has been releasing information about all the versions so we assumed it was their release. It is not.
We'd like to correct the information and give proper credit to the authors.
We are also hoping we can provide more information on these projects. Stay tuned.
