INTRODUCTION.

Thank you for choosing the X-RAY ARTF by SEAGULL EP. The X-RAY was designed with the

intermediate/advanced sport flyer in mind. It is a 3D airplane which is easy to fly and quick to

assemble. The airframe is conventionally built using balsa, plywood to make it stronger than the

average ARTF , the design allows the aeroplane to be kept light. You will find that most of the work

has been done for you already.Flying the X-RAY is simply a joy.

This instruction manual is designed to help you build a great flying aeroplane. Please read this

manual thoroughly before starting assembly of your X-RAY. Use the parts listing below to identify

all parts.

X-RAY. Instruction Manual.

!1) Carefully remove the aileron from one

of the wing panels. Note the position of the

hinges.

!2)Removeeachhinge from thewingpanel

and aileron and place a T-pin in the center of

each hinge. Slide each hinge into the wing

panel until the T-pin is snug against the wing

panel. This will help ensure an equal amount

ofhingeisoneither side of thehingelinewhen

the aileron is mounted to the aileron.

HINGING THE AILERONS.

Work the aileron up and down several

times to “work in” the hinges and check

for proper movement.

!3) Slide the wing panel on the aileron until

there is only a slight gap. The hinge is now

centered on the wing panel and aileron.

Remove the T-pins and snug the aileron

against the wing panel.A gap of 1/64” or less

shouldbe maintained betweenthe wing panel

andaileron.

Note:

!4)Deflect the aileron and completely

saturate each hinge with thin C/A glue. The

aileronsfrontsurfaceshouldlightly contact the

wing during this procedure. Ideally, when the

hinges are glued in place, a 1/64” gap or less

will be maintained throughout the lengh of the

aileron to the wing panel hinge line.

!7) Repeat this process with the other wing

panel, securely hinging the aileron in place.

!5)Turnthe wingpanel over anddeflect the

aileron in the opposite direction from the

opposite side. Apply thin C/A glue to each

hinge,makingsure that theC/Apenetratesinto

both the aileron and wing panel.

!6) Using C/A remover/debonder and a

papertowel,remove any excessC/A glue that

may have accumulated on the wing or in the

aileronhinge area.

The hinge is constructed of a special

material that allows the C/A to wick or

penetrateanddistributethroughout the

hinge, securely bonding it to the wood

structureof the wingpanel and aileron.

Note:

The control surfaces, including the

ailerons, elevators, and rudder, are

prehinged with hinges installed, but the

hinges are not glued in place. It is

imperativethat you properly adhere the

hingesin place per the stepsthat follow

using a high-quality thin C/A glue.
