The aircraft is from iris simulations. Now free from their classic series on their webpage. The texture is available on flightsim.com, do a search for irish air corps on it.
Nice video. Thats my Dauphin and my brothers Alouette model. There is a gazelle repaint we did ages ago to. Might go well in your collection. Haven't seen the G IV or the Garda 135 repaints before, look good.
