On the left in both pics is the Jenny Canuck tail assemblies.On the right the standard assemblies on most other models of Jenny.
As you can see there is quite a difference in their respective shapes.
Important note
in the interest of historical correctness) The Canuck tail assemblies as shown would be incorrect on a military version.They should be of metal construction and not wood.All other Jennys were wood.I took a little artistic licence here and made mine in wood as I felt on a barnstormer I could get away with it.Just about anything went in those days before the era of Air Regs.(That is one reason I stay away from military airplanes of this era as I like that sense of freedom when I build)
As you can see these assemblies were built right on a piece of foamboard with a wax paper layer between the plan and the assemblies.I used superthin superglue here as it soaks right in and leaves little residue.As far as the longterm life of superglue ,Ihave no idea, but I made sure that none of these parts were under any tension after being bent.
To bend the tubing I simply bent it around pins that were stuck in the foamboard,a little at a time.(See the rudder assy)
