The Ulsterman currently tops the FIA Junior WRC standings after a victory at Rally Sweden earlier this year and, whilst that still remains his focus for the season, a trip to the Azores was an opportunity not to be missed.
Armstrong will steer an M-Sport Poland-built Ford Fiesta Rally3 - similar to the one he campaigns in FIA Junior WRC - in the ERC3 category.
He hopes to gain gravel surface mileage with the car in preparation for WRC rounds later in the year.
“There are two rallies in the Junior WRC this year that are sort of slower, technical type of events in Portugal and Greece,” he told FIAERC.com, “so I think the Azores is a good way to get into the swing of things early in the season and getting my head around the style of driving.
“Hopefully it will give us a little more confidence for the remainder of the year, and the new ERC format looks really good. It’s really quite an exciting time to try an event in the championship, so that’s the main motive.
