don't use tooth picks they are too big and space the aieleron too far away. either buy some t pins or use regular common pins that come with shirts to keep the hinge from slipping too far in. Remeber glue all hinges on a surface at the same time and both surfaces of the connection point. What I mean to say is dont stick the hinges into the wing then glue them and then put the aielrons on and glue that because the hinge won't take glue a second time
