MULTIlock Uni-Set

The MULTIlock wing retainer system enables you to assemble the model quickly and easily, and secures the wings safely when the model is in flight. If the airframe is subjected to a sudden load (e.g. landing jolt) the wing retainer system “gives”, thereby absorbing excess energy and preventing structural damage. TIP: for additional security when flying in extremely gusty or turbulent conditions we recommend applying tape over the wing/fuselage joints.

The basic requirement for a successful installation of the wing retainer system is adequate structural strength in the fuselage and wings. In particular, the wings must feature stout root ribs in order to absorb the forces which act upon them. If you have any MPX model with factory-installed wing joiners, e.g. Alpina 4001, ASH 26, DG 600 evo etc., you can be confident that the root ribs are more than adequately strong. You will have no problems installing the system in these models. You may find it necessary to strengthen the root ribs of other models to cope with the loads (e.g. 3 mm birch ply). Models featuring flat steel wing joiners, and very large models generally, should be fitted with two wing retainer systems.

To dismantle the model and disengage the MULTIlock system, grasp the wing at the root leading edge (fingers over the spar) and rest the fuselage against your body. A quick tug on the wing will open the MULTIlock system, and the panel can then be withdrawn in the usual way (see Fig.1). The MULTIlock system can also be disengaged using the wedge supplied: push the wedge between fuselage and root rib, immediately adjacent to the retainer plug, to disengage the lock
