The wing on the Vantage FW is held on with wire hold down straps, the same way as the wing on the Bogey and the Spike. These are squared off U shaped wires, they are positioned at the front and the back of the wing and are pushed through to come out either side of the fuselage, the wires are then bent outwards at a right angle to allow elastic bands to be hooked on and wound around the fuz to attach to the hook on the other side. the bands don't need to be heavy or thick, smaller thin ones work better, you'll need a minimum of 2 bands at each end.
