Please Note: After removing kit from shipping box,
lay each piece flat on a hard surface, this will allow
the airframe to straighten out if lightly bent from
shipping. Do not worry since EPP is very pliable and
can be bent back if out of shape. Double check that
you have all the above pictured items. If any of the
airframe or hardware items are missing, contact TA

Bend them back on to each other as shown and let set for at least 2
hours. This will help to loosen up the movement of the surface.
(This is mandatory step)locate the hinged items as shown above, 2. Make a neat line of hot glue over any old credit card and spread it
over the hinge line show in the next picture.
3.
layer over the hinge line otherwise if put directly over foam you might
end up melting EPP.
It is very important to put glue on card first and then spreading a thin 4. It is not required to put glue all the way to hinge line just a inch of
glue on both inboard and outboard of the surface will do the job.
5.Here is the right amount of hot glue spread over the hinge line. 6. Building surface should be at least 2ft x 4ft and flat, use a wax paper
over the surface to avoid sticking EPP on it when gluing.

edge of wing, like shown above.
9. Make sure to lay down the wing on the flat surface while glueing the
CF stripe.
10. Turn back the wing to glue down the reinforcement rods, if needed
use a scissor or a ball point pen to loosen down the pre cut laser lines.
11. For rear wing re-inforcement,insert the supplied 1mm rod into the
pre cut slot. (Check the page 4 of exploded view for more clear idea)

the required length from the supplied 1000mm rod or from any excess
remaining rod from the previous steps.

rod spanning the entire length from the rear wing spar to the horizontal
stab spar, cut the required length and insert the rod into the precut slot
like shown above.
41. Make sure everything is flushed, Use a thin CA to glue it. 42. Hit with kicker and verity that there is a good solid bond, if there are
loose areas simply add a little more CA and Kicker.

crosses the center support, as indicated above, and cut the rod.
50. Once the rod is split, locate the opposite end of the rod, insert it
into a pre cut slit like shown above.
51. Once happy with the location and flatness of everything, glue the
ends and center area with CA.
52. All truss rods shown in position. Make sure the aileron is at on the
work surface and that the center support is still square.
