Tail feathers


We need the stabilizer next so while we have the stuff out let's do the fin too.
Cut the horizontal stab using the pattern from the plans.
Cut the elevator free and sand the leading edge to a point.
Drawing a center line to the edge will help to keep you from over sanding.
Push the elevator against the stab and push a pencil tip in the slot to make identical marks so the hinges will align easily.
Install the hinge material to the control surfaces and let it set up.
Cut the slots to its mate install the elevators and let it set up.

Bend the crossover wire to connect the elevators then use it to mark its position on the stab.
Smashing the wire against the foam will leave a mark easy to see.
Use a heated wire to make slots in the elevators and bond the wire in place with epoxy.

Note the use of a flat surface and weights to hold the surfaces parallel. Sand a groove in the filler piece to clear the wire.

Apply a small amount of epoxy to the tips of the end you sanded the groove in and slide it against the stab. Don't get sloppy here, you don't want to bond the wire.
Sand the edges to a round contour on the entire Horizontal stabilizer.

The Rudder control wire is enclosed like the elevator wire was.
So,
Cut the rudder free and prepare the hinges.
Before you install the rudder to the fin, bend the torque wire and drill a hole in the rudder so it can be bonded to the rudder.
The lower filler piece will need a groove for the torque wire to be hidden.
I used a thin heated wire to melt the groove then used epoxy to hole it in place.

Note that the bend at the bottom is slightly shorter than a servo arm.
A hole in the stabilizer will be needed to install the fin but that will come later.

Back to the fuselage


Place the wing on two blocks of equal size to get it above the table.
( The control horns and cables on my wing made this necessary.)

Slide a 6 mm strip under the trailing edge of the wing and put a weight inside to hold it all in place.
This will set the angle of the stabilizer.

Measure the top of the fuselage side sheeting at the last fuselage former.

Draw a line parallel to the table top to the next forward former. Cut the side sheeting to form the stabilizer mount.

Horizontal Stab installation


The fuselage is still Fairley flexible so a little care is needed to not change what we have.

I blocked up the last former to hold the weight that I will apply while the glue sets up.

Test fit the stabilizer to the fuselage to be sure it will bond in place parallel to the work surface and centered.

Apply glue to the top of the fuselage sides Just enough to make the edge glossy.
Put the stab in place and hold it with a small weight.

Vertical stab installation


Cut the hole for the rudder torque rod and bond the fin in place on top of the stabilizer.

Use a 90 degree block or tool to hold it vertically and on the centerline.
Important! , As it dries look at it from every angle to ensure it is in line

First plastic


Trim the flanges away from the plastic parts leaving about 1/4 inch.
Lay the parts on a flat work surface and use a standard pencil to mark a trim line while it lays in its side as well.
Use scissors to trim the line.
For the fin slot cut it from the inside allowing the blade to follow the inside corner.
Several light weight cuts are better than one heavy.

Flip it over and put the blade thru the slots and pull the blade thru the curved portion.
The slots for the stabilizer is very close to net trim so follow the lines. we will final trim them next.

Place the aft turtle deck ( plastic part) on the fuselage frame and hold it in place.
Mark the Slot for the stabilizer using a shim as A guide.
This depressor was the thickness I needed.
Note the air gap at the front of the stabilizer.
After trimming the gap will be gone.
Repeat the step if the plastic is not sitting on the formers.
While you are cutting mark and trim the plastic to match the forward former.

Bonding


In the past I used gorilla glue to attach the plastic to the airframe.
Still do but I have found that spray 77 adhesive holds the edges down neatly with no need to use tape while the gorilla glue sets up.

The fuselage is still a little flexible at this point and the addition of the plastic could introduce a twist if you are not careful.
To prevent this; support the stabilizer with two equal sized foam blocks and weights to hold it there.

Tape the outside of the plastic edge to prevent the adhesive overspray from getting there. Spray on the adhesive to the edge and remove the tape.

Apply the gorilla glue to the formers and put the plastic in place and rub the edges down.
