Lengthen the servo leads using the stated extension leads. Glue the servo mounts in
the wing in such a way that the pushrod points directly at the control surface horn.
The servo for the airbrake is installed in the wing using the plastic mounts provided,
so that the pushrod points directly at the cross-hole in the swivel pushrod connector.
Assemble the control surface pushrods from pieces of M2.5 studding, M2.5 nuts and
M2.5 clevises, as already described for the outboard wing ailerons. Measure off the
length of the pushrod from pivot pin to pivot pin, and cut suitable pieces from the
M2.5 studding supplied in the kit. The two plastic mounts for the airbrake servo must
be reduced in height by about 1 mm, so that the servo can effectively be clamped in
place.
Installing the airbrake servo: place the servo in the mount in such a way that the
pushrod fits through the cross-hole in the swivel connector (as seen in the photo).
Use the transmitter to set the servo to the “brakes retracted” end-point, and hold the
airbrake closed by pushing gently on the pushrod. Now apply a drop of UHU
schraubensicher to the grubscrew in the swivel pushrod connector, and tighten the
screw firmly to clamp the pushrod.
The servo well covers are held in place using strips of adhesive tape.
Installing the wing retainer system
Apply glue to the wing retainer plugs before screwing them in the holes in the wing
roots as far as they will go.
Screw the two aluminium threaded sleeves onto the length of M8 studding, and cut
down the assembly to a length of about 130 mm. Screw the two quick-release
couplings into the aluminium threaded sleeves.
Assemble the model temporarily in order to check the wing retainer system: engage
the retainer plugs in the quick-release couplings and set the threaded sleeves to the
correct length, then remove the assembly again and unscrew the quick-release
couplings by about 5 mm to enable you to apply thread-lock fluid to the parts. Apply
the fluid, then re-assemble the retainer system and rig the model completely. Check
that both wing panels make proper contact with the fuselage, and that both quick-
release couplings are fully engaged, then leave the thread-lock fluid to cure fully.
The quick-release couplings are disengaged by pushing the union ring back using a
screwdriver; the wings can then be released from the fuselage and pulled off. The
wing retainer system also acts as a compression strut to absorb the loads when the
wings swing forward in a hard landing.
Installing the ON / OFF switch and receiver battery
Install the ON / OFF switch in the plate in the fuselage nose using the retaining
screws supplied with the unit. The receiver battery can be attached to the plate using
Velcro cable ties, as shown in the photo.
If you wish to launch the model by aero-tow, the coupling mechanism (Order No.
2890 or 7890.2) should be epoxied into the fuselage nose. The release servo should
be installed in the plate in the fuselage nose. If you are using the coupling No. 2890,
