Airframe Description
Continually providing high performance and durable EPP
foamies, JTA Innovations took yet another leap forward
with the release of the 33” MXS. In 6mm EPP just as the
previous Gamebird, the MXS is an excellent compliment.
Tested by high profile 3D/freestyle pilots here in the United
States, the MXS has proven to satisfy some very technical
demands. Both striking color schemes are designed by Kim
Quenette and are sure to catch attention. JTA Innovations
also introduces another development in the carbon fiber
construction technique with this release. The use of flat
carbon fiber throughout the airframe not only improves
durability reducing flex and wear on the EPP, but also helps
keep mass centralized in certain parts of the airframe.
Recommended Equipment:
Motor - Hacker A10-9L, T-Motor AT2303, equivalent
ESC - 10-15 amp
Servos - 6-12 gram (Qty. 3)
Propeller - 8-9” (APC Indoor SF highly recommended)
Battery - 2S or 3S 350-750 mAh depending on motor/ESC
capabilities

Aileron linkages: 70mm long each
Elevator and rudder linkages: 400mm long each

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.

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.
www.modellmarkt24.ch

www.modellmarkt24.ch
You can now prepare the bottom half of the fuselage. Test fit this into each
slot as shown above before glueing.
www.modellmarkt24.ch

www.modellmarkt24.ch
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.
www.modellmarkt24.ch

www.modellmarkt24.ch
Using the marks that you just made, place your glue along the fuselage.
www.modellmarkt24.ch

www.modellmarkt24.ch
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.
www.modellmarkt24.ch

www.modellmarkt24.ch
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.

www.modellmarkt24.ch
Just like the aileron bracing, it is very important to use weight towards the
wing tip while the carbon wing bracing is setting to keep the leading edge of
the wing as straight as possible.

Shown above is one of the carbon fiber landing gear legs that come pre-glued
to the axle. The larger of the two EPP foam circular collars will slide on first.
No need to apply glue to anything quite yet.
www.modellmarkt24.ch

www.modellmarkt24.ch
Next, with no glue needed, slide one of the wheels on to the axle all the way up
to the first foam collar. Make sure it is spinning freely.
www.modellmarkt24.ch

www.modellmarkt24.ch
Now locate the plywood/carbon fiber laminated collar to slide up next to the
plastic wheel. Once again, do not apply glue yet as the tire will need to spin as
freely as possible around the axle.
