Here's what it looks like finished.





I switched to the North Pacific prop because it has a shallower pitch than the EB prop and is easier for a single loop of 1/16" rubber to swing.  A small drag tab was added at the dihedral break on the left wing to insure a tight left turn.  Someone suggested that with the triple tail I should have called it "Bostillation."

Bob,

Max wing span for a Bostonian is 16 inches.  This one is just under.

KK: that is just too pretty, what is the wing span? I also have no idea what EAYGA stands for!

kk...what a great looking Bostonian.  She should be a great flyer.  Best of luck with her!  No idea what EAYGA stands for!

Here's the other thing that has been on my workbench along with the Arrow and the Beaufighter No-Cal.  It's a Bostonian for a local contest that I call the Irish Jumping Bean.  This is a formal project using full EAYGA standards. (Beaufighter No-Cal to the first forum member who can tell us what that means.)

Here is a shot of the parts on the bench.



I stuck it together with a few dabs of "Green Glue"  (Comes apart with a whiff of acetone.) for a "bones shot".



Since this is a bit delicate I decided to cover dry and shrink with alcohol instead of covering wet.



Here's how it looked before shrinking.



I got my pin down setup ready before shrinking the wing covering.  It's a 95 degree day, about 82 in the garage, and I had to be all setup to work fast because the alcohol would start drying almost immediately.



Here's the wing wet and drying.



Fuselage is dry in this shot and waiting for a misting of Krylon #1305.  That upper longeron should have been stiffer and I had to sister in another piece when I cut out the window holes.



I'll try not to forget my camera for video tomorrow.
