It seems like your local hobby shop is not carrying the correct equipment. I've seen a couple other posts of yours where you had problems getting some equipment/accessories. At this point, It maybe worth while to invest some money and order some things online and pay for the shipping (even if you have to do an international order). Make a comprehensive list of only the stuff you can't get locally.....apparently epoxy, the keystone of model flying, is one of them. Order a large amount (large bottles) that will last you. Order both slow and fast drying ones because somethings just don't need 30minutes to cure (5 minute works well in these cases).
