Don't forget that while all this other stuff is going on I've been working on the fuselage filling the weave with epoxy and wet sanding as described in the book.
Now that the wing is getting the epoxy/ glass coat the fuselage is getting the leftovers.
This will happen again when the tail feathers get the glass; the wing will get the leftovers.
Its all little jobs that take time to cure or dry so don't feel bad about walking away for a day.

Tail feathers.


The tail feathers take a bunch of time but not much space so the fuselage and wing glass work continued while I worked the next portion of the plane.
Starting with a sheet of inch thick foam.
Lay the plans over the foam and poke holes thru the paper to leave the pattern in the foam .
Its called pouncing and has been used by dress makers since before we were all born.

Rudders


When I designed my Mohawk I skipped rudders because I was afraid it would make the model tail heavy.
This was a mistake because with three fins, weathervane during the takeoff roll is a problem.
Not to make that mistake again I gave the constellation all 5 rudders.
There is some monkey motion back there and its not easy to arrange but it is very light weight and Im glad I went to the trouble.

Cut up the tail feathers and add the balsa liners to the hinge lines and gaps.
Notice that the control surfaces have thicker balsa strips at the hinge line so you can sand the V shape to give the hinge clearance.
There are 17 parts in all , group them together and mark the edges for identification .
I use color markers.

Use a sharpie pen to draw a center line around every part.
Playing cards make good shims for this step.
Just for fun I wanted to see what the starting weight is for comparison.

sheet cutting


Today I had to cut foam sheet stock for another project.
Using parchment paper on the table surface makes it easy to produce smooth trouble free cuts.
I found that I could use lower temps and lighter weights since the foam slides much easier.

Thanks You for the tip Goldguy

I always try to use a Bud Light can as reference when doing pics. Of course by the time that I am taking pictures, the can is empty
