Building instructions
Thank you for choosing a quality product MADE IN GERMANY.
Please read these building instructions and suggestions prior to construction, then carefully
proceed with the step by step construction.
PRESENTATION OF THE MODEL
The wings are constructed in three sections with carbon tube spars.
The wing joiners are built into the spars.
The wing profile used is the AG35.
The fuselage sides are reinforced with braces and stiffeners.
Wing ribs are precut to accept the carbon spars.
The tail feathers are builtup from trussed balsa parts.
The system is designed to use ORACOVER for the wings and fuselage, and ORALIGHT2 for the
tail feathers.
Due to the long nose and lightweight drive components, balancing the tail is as easy as possible.
Specific glue icons are shown in the relevant sections of the building instructions (NOTE: In this
English translation, the type of glue is specified between parentheses instead). For superglues
we recommend using normal cyanoacrylate (CA) and thick cyanoacrylate (thick CA, with a
slower set time).

Sheet 72.08
Parts H H8
●Cut out the plan and cover with transparent film (cling wrap film or polyethylene).
●Glue together the tailplane parts H to H8 (thick CA).

●Check the fit of diagonal braces H9 to H 2 and glue into place without warping theframe
(thick CA).

Part H28
NOTE:This step is only required if building a removable elevator.
●Glue ply pieces H28 in the holes of the centrepiece H3(thick CA).

Parts H 3-
H25
●Glue the elevator parts H 3H20 (thick CA).
●Check fit then glue the diagonal braces H2 to H25 without warping the frame(thick CA).

Part H26
●Figure . Glue together (stack) the two plywood elevator connectors H28(thick CA).
●Figure 2 and 3. Glue the connectors to the centre of the elevator(thick CA).
●Figure 4. Sand the tailplane and elevator according to thesections shown on the plan.

Parts S -S7
●Glue the rudder parts S to S7(thick CA).

Parts S8-
S 6
●Glue the rudder parts S8 to S 6 (thick CA).
8
Sheet 72.07
Parts S 7-
S22
●Check fit then glue the diagonal braces S 7 to S22 without warping the frame(thick CA).
●Sand the rudder to the sections shown on the plan.

Sheet 72.02
Parts R ,R2
NOTE:In the following phases be sure to make one lefthanded and one righthanded fuselage
side.
●Glue the front and rear side portion of the fuselage walls R and R2 (thick CA).
●Cut out/file out the slots for the pushrod sleeves in the lefthand fuselage side infront of
the drilled hole,and behind the drilled holein the righthand fuselage side.

Sheet 72.05
Parts R3,R5
NOTE:Build experience from the EN translators suggests to perform the following three
steps in reverse order.
●Glue together the lower fuselage doubler parts R3 (front) and R4 (rear)(thick CA).
●Glue the lower fuselage doublers R3/R4 flush with the fuselage side (thick CA). Beware
of the pushrod hole position.
●Glue the upper fuselage doubler R5 flush with the fuselage edge(thick CA).
Sheet 72. 4
Parts R6,R7
●Glue the wingbed doubler R6 and front fuselage doubler R7 flush with the fuselage edge
(thick CA).
2
Sheet 72.05
Parts R8-
R 7
●Glue the stiffeners R8 to R 7 (thick CA).
●NOTE:Pay attention to the orientation of the slots in R 2 to R 6 (to accept the fuselage
stiffeners R23 to R27 in step 9). The slot in R 6 is reversed compared to the slots in
R 2 to R 5. This is to ensure correct alignment of the pushrod sleeves and smooth
running of the pushrods.
3
●Clamp both panels together and sand the outer edges.

Parts R 8,
R 9, R2
Small parts
bag Part
R6
●Align and glue together (stack) both R2 parts using clamps (thick CA).
●Align and glue together (stack) R 8 and R 9 using clamps (thick CA).
●Glue the nut R6 using epoxy (5 minutes epoxy).
WARNING:Ensure no glue gets into the threads.
5
Sheet 72. 4
Parts R20
●Glue the wing saddle R 8/R 9 at right angle (5 minutes epoxy).
●Glue the R20 and R2 ribs exactly perpendicular (thin CA).
6
●Glue the second fuselage sidewall assembly. Use the same adhesives as in step 5.
●Check with a right angle that the fuselage sides are properly aligned with each other.
