The helicopter simulation of the UH-1 Huey for the DCS series has been released. It was created by the company Belsimtek in partnership with Eagle Dynamics. It is a “study sim”, with a fully clickable cockpit and an advanced flight model. You can “pre-purchase” the sim for $49.99 USD, which means you can pay to gain access to the Beta, as well as own the release when it is finished. It requires downloading the DCS World product, which is common base for all DCS sim aircraft (think of it like an Operating System for sims).
