This is a post from 2011, whether they are still active I don't know
"There are a few clubs in the area although many have full memberships ! Dolores model shop have just started a new club and they are taking new members. There is another club in El Relengo that is mainly Spanish weekends and expats week days although I think their membership is full. There is another club just outside of Bigastro and one in Torre Pacheco. Maybe a good idea to attend one of the open days to get more info, I can email you a copy of the years planned events in the area. To fly you must be a member of a club and have insurance, it can be a dangerous sport especially in the hands of a novice !! PM me if you would like more info"
You would probably better looking for any RC model shops, they may have adverts for clubs in the windows.
