Miltech Simulations came out with a very nice projects update on Facebook. The company talks about its SuperCarrier, but they also mention the CH-47D for Microsoft Flight Simulator.
According to the company, the Chinook is now in Alpha stage, meaning “all systems, sounds, flight model, 3D model and textures have been completed”.
The next stage includes further “detailing, improvements and "special features" - such as loaded cargo, detailing of the cargo bay, liveries, etc.”.
As for a possible date of release, there is nothing set in stone at this time but Miltech Simulations says a Beta maybe out in about a month and a half and version 1.0 could be released in 2.5 months.
