My LAK 12 has a combination of automatic and manual control hook-ups.
The maual ones fit easily and are a pleasure to use - tha automatic
ones rely on the wings (flaps) and elevators being lined up perfectly
before the final push. If everything in not perfectly lined - the
links tend to damage the sockets into which they fit and the whole
wing does not go on - not an ideal situation. Modern automatic hookups
look fantastic but poorly designed ones are no easier than manual hook-
ups.
