Fuselage formers
these are the fuselage formers from front to rear.

Fuselage parts
Locate the left and right fuselage sides and the two fuselage doublers.
The bottom is also shown here. Keep in mind that the cut-out area for the hatch has to go on the OUTside later in the building process.

Fuselage parts
Place the fuselage sides with the pockets to the inside and glue the doublers in place using white-glue. Take care to align the parts along the edges.
The pockets are not visible in these buiding instructions as there where added in the later models.

Take a dremel and sand the edges of the motor-area, this is ony required for large motors and can also be done later.

Locate the two parts for the wing mount

Glue the parts on top of each other, taking care to allign the hole and the edges

main bulkhead
locate the two parts for the main bulkhead

main bulkhead
Glue the parts on top of each other, taking care to allign the hole and the edges

Test-fit all the formers in the fuselage, the first motor-former can be fitted later.
First the rear of the fuselage will be glued.
When all rear formers fit, use white-glue to fix them in position.

Temporarely (NO GLUE) fit the bottom of the fuselage to allign the fuselage sides.
Use tape and clamps to hold everything in place until the glue is dry

time to glue the motor former in place.
To ge the correct rounding of the fuselage sides we use the battery tray as guide
Try fitt all the parts first. It might be required to enlarge the slots in the fuselage that hold the motor former.

Then glue the battery tray and motor-former in place. Some force will be required to get the fuselage sides bended so the touch the motor former.

Sand the bottom of the fuselage, test fit the bottom. Did I mention that the hatch will go to the OUTSIDE. If all fits , glue and pin the bottom in place.

Now also glue the bottom rear part in place.

Sand the motor-former flat with the fuselage sides.

Glue the nose-doubler in place

then glue the bottom and top part of the nose in place.

Place the electric motor in the fuselage with two bolts, then place the spinner backplate on the motor axis.
Use a pencil to draw a circle close around the spinner backplate.

It should look a bit like this

Next up is some serious sanding, I have the luxury of a nice tool for this !
but with some fresh sandpaper and a sanding-block will do the trick

after some time it should look a bit like this. Final sanding will be done when the hatch is build.

You will notice some holes in the corners of the fuselage, these needs to be filled.

so cut some little pieces of balsa, 30mm long, 10x10 wide, and then cut it as shown in the picture, the lowest piece of balsa

Glue these pieces in the corners. Then sand flush with the plywood.

before closing the fuselage, it is a good moment to glue the outside tube for the elevator in place.
Leave some length on the inside of the fuselage

(this picture is from the Slipher fuselage so it looks a little different)

finally the fuselage can be closed.
This is an important step because after the top is glued in place the fuselage will becomse torsion free. So take your time to allign the fuselage.

When dry, all the edges of the fuselage can be sanded round to your liking. When you are satisfied with the shape of the fuselage then it's time to remove the small support bar where the horizontal stabilizer will be placed.

if you already did build the horizontal stabilser then you can test fit.
