Fellow Europaphiles,

If the tailplane moves outboard and disconnects from the TP14 pins  
something else happens that's very bad.  The anti-servo/trim tab  
comes free from the control "T" rod.  You now have a free-floating  
tab hinged on the front edge with CG well back from the hinge.  You  
now have the perfect setup for a fluttering trim tab.  Matter of  
fact, it will probably flutter at a much lower speed than you might  
expect.  Flutter the tab and you are surely going to flutter the  
stab.  We all know how powerful the stab is.  You will have to make  
the aircraft get real slow real fast or it's going to come apart.   
Maybe you can't even get slow enough to stop it.

Good building and great flying,
Bob Borger
