Hi Darren the way I get rods down a fuselage and out of the slots, is I use a length of air line, type we use for retracts just push it in the slot and down inside the fuss push the end of the rod into the tube its a tight fit then pull it back out ,if its a twin just send two ends down ,if the thread is on the end of the rod it grips great in the tube and you can really pull it through and out the sides never fails .
