Actually, I own 4 ARFS which came with these hinges and I installed them on all control surfaces by doing exactly that...I applied thin CA..I pushed em in one surface...I applied it to the other end of the hinge and pushed the surface in...all four at a time or whatever there was..3 on a rudder...4 on an aileron, etc.... all 4 plances have flown for a few years with no problems and I cant get them to come loose...also..they all went together easily and with NO gap..VERY VERY minimal gap....less gap than with the older metal hinge types...
