I dont see it as a problem either,,I build 1/2a and very often (almost always) will take one of those slotted ca hinges and cut it in half....I will make sure its gonna fit where its supposed to, then take it back apart and glue one side...never had a problem with a hinge coming out yet, never pinned one either...I did once take a $3 foam glider plane from k-mart ,cut a few inches off the nose and stuck an .049 on it, finally got it balanced and used monocote hinges full length of the rudder/elevator and on the 2nd flight the flutter got so bad the thing literally exploded, the whole tail floated down in 50 pieces......Rog
