Airframe Description
Welcoming in the 4th year of JTA Innovations, the 33” Edge JD is a perfect
representation of how we have reached the pinnacle of aerobatic flat
foamies with both it’s flying characteristics and presentation. The Edge JD
offers every forgiving 3D characteristic that you could expect from an Edge
along with the all around precise performance you’d expect from a JTA
Innovations airframe. The abundance of side area allows for excellent knife
edge and precision flight while keeping the aggressive possibilities that we
have all been accustomed to with JTA Innovations airframes. The Edge JD
will be sure to complement whichever type of aircraft lineup you have with
it’s unique blend of looks and flying characteristics. Additionally, the
standard JTA Innovations construction technique is included on the Edge
which will provide several demanding flights indoors or outdoors.

Kit contents shown above (Extra JD shown for representation)
Below are lengths of control surface linkages. Linkages are
used from the provided carbon fiber rods.
Aileron linkages: 65mm (x2)
Elevator linkage: 365mm (x1)
Rudder linkage: 365mm (x1)

As shown above, the aileron bracing is done using flat
carbon fiber glued into the slots creating durability for the
aileron. Please see the carbon fiber diagram for your
airframe to determine which size carbon strips are to be
used.

Wing bracing shown above. The center wing spar is the
supplied carbon fiber square stock.
Cowl glued to the fuselage.

The horizontal piece of the fuselage also uses flat carbon
fiber spanning the entire length from the rear wing spar to
the horizontal stab spar.

Elevator flat spar and h-stab flat spar shown above.
Now that rigidity is established, it is very important to break
in the hinges by flexing them all the way over and weighing
them down. Let them rest for at least 60 minutes.

You can now prepare the bottom half of the fuselage. Test fit this into each slot
as shown above before gluing.

If deciding to place glue on the horizontal part of the fuselage, you can mark
out where the glue will be placed as shown above after test fitting the fuselage.

Using the marks that you just made, place your glue along the fuselage.

It is extremely important to make sure that the bottom vertical part of the
fuselage stays 90 degrees to the horizontal fuselage while the glue is setting.
This can have a huge effect on the flying characteristics.

The provided EPP square may be useful during this process of gluing the
bottom fuselage piece.

Now that the bottom fuselage piece is glued into place, you can locate the
carbon fiber rods used for the wing bracing. Shown above is the wing joiner
used to guide the wing bracing. Some airframes may have a larger gusset or
joiner that overlaps the leading edge. You will also find dots towards the tip of
each wing to determine where to glue the carbon rods. The same goes for the
location on the bottom part of the fuselage. There should be four total carbon
rods for wing bracing. Two will be used on each wing. Lengths can be found

on the carbon fiber diagram.
Above is a photo of what your gusset may look like depending on your
airframe. Also some of the completed carbon fiber rod construction is shown
above.

Shown above is the wing bracing glued into the bottom part of the fuselage.

Just like the aileron bracing, it is very important to use weight towards the
wing tip while the carbon wing bracing is set up to keep the leading edge of
the wing as straight as possible.
