I think the trick with neodymium magnets is getting the right size. They come in a fairly wide range of sizes, which basically determines their attractive force so you have the flexibility to select just the one you want. I’ve used them a few times and think they are an excellent solution for holding bits and pieces in place on the model.
First up, these two side lockers are held in place by magnets on the lower edge. They hook under the thwart at the top and click into place at the bottom, hiding the battery and the electronics.



Then similarly this steering gear hatch is held with a couple of small magnets on either side. None of them are two strong so the covers remove very easily by hand but its just enough to ensure that they are never going to come adrift in operation.
