Based off the high performance full scale aerobatic machine, the Game Composites
GB-1 Gamebird, the new JTA Innovations 33” 6mm EPP model is sure to catch
attention both on the ground and in the air. Developed under approval by Philipp
Steinbach, there is no doubt it compliments the outstanding characteristics of the
full scale. The Gamebird is constructed with the same carbon fiber technique that
has held up on the JTA 32” Yak and high quality hardware that will greatly
increase the longevity of the airframe. Excelling in all areas of flying, the
Gamebird is aimed to please any type of RC aerobatic pilot, whether that is the
beginner 3D pilot or advanced freestyle pilot. Not many other foamies have the
wide range of flight envelope of the JTA Gamebird. It is available in the Green
Game Composites color scheme made popular on the full scale version, as well as
the blue and red “Cotton Candy” color scheme designed by Matt Stringer.

* Below are photos of the new construction version for reference. This replaces
some features (aileron gusset bracing for example) that are listed later on in
the manual. If you are assembling an older version, please move on to the
manual where the control surface break in begins.*

In order to get a consistent full range of all control surfaces during flight and
setup, we recommend that the first thing you do after unboxing is weighing
down the control surfaces as shown above. Each surface will take about
60-120 minutes to complete, then you will notice that it will be easier to move
the surface to full deflection.

Pictured above is the bottom of the fuselage on some wax paper, as well as the
wing panels and the horizontal tail. Test fit these pieces, then when confirmed,
glue into place.

Once the horizontal tail is glued into place, locate the elevator spar. You will
see the location where this will go in the elevator. This will be the shorter of
the two carbon fiber square rods (the other will be used for the wing spar).

Pictured above is the wing spar in place. Test fit to make sure it crosses
through the fuselage with no issues before glueing.

Locate the joiner that has one hole cut in the top. This will be the aileron
brace joiner. You will find two (one for each aileron). Glue this into place
while making sure it is 90 degrees to the aileron surface.

The other joiner that has two holes in the top will be for the wing bracing.
Also, the cutout at the bottom will fit over the top of the wing spar. Glue this
piece into each wing also making sure that it is 90 degrees to the wing.

Pictured above and below are all four joiners in place, as well as the wings and
horizontal tail.

Shown above is the aileron bracing meeting together at the joiner. You should
be able to notice the dots on the inboard and outboard sides of the ailerons to
help you determine where to glue the carbon rods. It is best to have weight on
both sides of each aileron to prevent warping while the glue is setting. Aileron
bracing carbon fiber rod lengths:
Outboard forward: 179mm
Outboard aft: 160mm
Inboard forward: 160mm
Inboard aft: 140mm

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

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.
