I created a clamp that can be used to make the wings removable on the Reptile Sky Shadow S800. Cut out a section of the wing for the clamp to fit into at the root of the wing where the wing buts up against the fuselage. Glue (I used hot glue) the clamp in place so that it is flush with the bottom of the wing and so that the main spar can pass through the hole. The clamp can then tightened using a 3mm screw while holding the wing in place. Works quite well and certainly better than magnets or velcro. You could probably glue a clamp into the front spar area as well to be safe.
