Cut down the two servo output arms
㉑
as shown, leaving
just the innermost hole. Screw the HS-85MG servos
#112086
to the servo plate
4
. Now centre the servos from the trans-
mitter, and fit the output arms on the output shafts at a 90°
angle to the long side of the case. The output arm of the front
servo should face right as seen from the tail of the model; the
arm on the rear servo should face left. Now glue the completed
plate (with servos) in the fuselage, with the underside of the
servos touching the floor. The front edge of the plate should
end flush with the cable exit slots in both wings
Fig. 10
.
Remove excess material from the ball-links
8
, in order to
maximise the possible angular travel. Cut one pushrod
6
to a length of 170 mm, and the other to 123 mm. Solder the
threaded couplers
5
to the unthreaded end of the pushrods.
Now screw a ball-link
8
on one end of each pushrod, and a
clevis
7
on the other end.
The longer pushrod can now be connected to the rudder vec-
tor, and the shorter pushrod to the elevator vector. Adjust the
length of the pushrods so that the vector unit lies parallel to the
rear edge of the motor cylinder in both axes
Figs. 09 + 11
.
The ROXXY BL-Control 755 S-BEC FunJet 2 speed controller
#1-01010
is enclosed in a heat-shrink sleeve. Cut two small
slits in the sleeve between the motor wire exits. The speed
controller can now be mounted over the wing spar using the
two cable ties
㉒
Fig. 12
. Run the controller wires below
the servo plate, then connect them to the wires attached to
the motor.
Install the Wingstabi / receiver in the model with the aerial
facing forward, and deploy it in the appropriate slot in the wing.

Screw the ball-end bolt
8
in the hole in the motor bulkhead
2
in the location shown. If the bolt is not a tight fit in the
hole, apply a drop of Zacki to secure it. Hold the self-locking
nut
⓫
in the correct position on the outer ring, and screw the
second ball-end bolt
8
into it from the opposite side; take
care not to over-tighten the ball-end bolt, otherwise you risk
stripping the thread. Place the motor bulkhead centrally in the
outer ring
1
, so that the pivot pins
⓬
can be fitted. Push
the pivot pins into the holes, and check that the parts swivel
freely
Fig. 06
; you may need to relieve the motor bulkhead
slightly to achieve this, sanding it lightly by hand. When you
are satisfied, apply a small drop of Zacki to the outside of the
outer ring to prevent the pivot pins shifting. Now screw the
ROXXY BL Outrunner C35-30-2700kV motor (
#1-01297
) to
the motor bulkhead using three socket-head screws
⓭
and
the two spacers
3
; ensure that the motor wires will be on
the underside of the fuselage when installed
Fig. 07
.
Locate the ring-screws
⓾
and drill out the holes to 2 mm
Ø. Cut the threads in the two holes in the motor cylinder using
the standard FunJet motor mounting screws, then screw the
two ring-screws into the holes in the motor cylinder to a depth
of 8 mm
Fig. 08
. Check that the holes in the ring-screws are
orientated correctly. Now position the assembled vector con-
trol unit between the two ring-screws, and fit the two socket-
head screws
9
to secure it. Route the motor wires inside the
fuselage leaving plenty of slack to ensure maximum freedom
of movement of the vector unit
Fig. 09
. Check carefully that
the parts swivel freely. You may need to bend or rotate the
ring-screws slightly to achieve this. Apply a little Zacki or hot-
melt glue to secure the motor wires to the fuselage where they
pass through to prevent them shifting.
