To complete the modifications (see part 1), I felt that not only should the attachments be secure but it should also not require too much effort to remove the elevator.   The plastic plate that will be glued to the elevator has a plastic tab that gets ‘locked’ to the plastic plate on top of the rudder.  To remove the elevator one needs to ‘lift then pull’ that piece of tab.  If you ask me, its too small and requires some unnecessary effort which can damage the damned thing.  Here’s what I mean:

It would have been great if they added more plastic to this tab.  At any rate, the solution is straight forward, get a paperclip or metal cable tie (my preferred choice) and make a small hole near the tip of the tab like so:

And here’s the finished mod.. which can be easily accessed using whatever tool is at hand.
