Henry Struck's 1937 Benny Boxcar in 47 inch span for 1/2A



 
The empennage is removable, held in place by the 2-56 rod shown.  The fin front spar extends down through the ply plate, and the fin rear
spar is trapped between the fuselage sides.  The stabilizer is clamped in place by the fin.




A bottom view.  The rudder is held and pivots on the screw in the ply plate at the end of the fuselage, the screw also serves as a tail skid.  
The elevator center hinge/retainer is also visible  above  the rudder, made of a wire bent into a U-shape and glued into the aft spar of the stabilizer.
There is a balsa shim in front of the elevator joiner to space the elevator back from the stabilizer spar.



Visible here is the top of the 2-56 retaining rod, bent into a U and inserted into the bottom fin rib so it will not turn.  The other side goes through a
small ply reinforcing plate.  The connectors for the control threads are made from small electrical wire terminals soldered to threaded
brass rod ends.  The control arms are detailed on the plans and are from 1/16 hard ply.   They are included in the short kit.  
Note the balsa surrounding where they pass through the elevator.


Some extra balsa framing allows for the pass through of the rudder control threads.  The areas where the threads will pass through depends on
the specifics of the radio installation.  It is best to determine the location where the threads pass through before covering.  It is handy to use a
length of music wire to do this.
