STEP 9: ASSEMBLING AND INSTALLING THE ELEvAToR PUSHRoD ASSEMBLY
q
Cut two pieces of wire to a length of 38mm (1-1/2"), then make a 5mm
(3/16") long 90º bend in one end of each piece of wire. Next, make a very short
90º bend [~1mm (1/16")] in the other end of each wire.
imporTanT
The short 90º bend will help lock each wire to the carbon
fibre rod when the heat-shrink tubing is installed.
q
Cut two pieces of heat-shrink tubing to a length of 38mm (1-1/2"), then cut one carbon fibre pushrod to a length of 495mm (19-1/2").
q
Attach the longer 90º bend in one piece of wire into the hole that is ~13mm
(1/2") out from the centre of your servo arm, using one snap-keeper.
q
Slide one piece of heat-shrink tubing over one end of the carbon fibre
pushrod.
q
With the end of the carbon fibre pushrod pushed against the back edge of
the snap-keeper, slide the heat-shrink tubing up over the wire, then use a heat
gun to shrink the heat-shrink tubing and secure the two parts together.
q
Centre the elevator servo (the servo on the right side of the fuselage), then
slide the plain end of the carbon fibre pushrod through one predrilled hole in
the plywood pushrod support on the carbon fibre tail boom, then through the
predrilled hole in the bottom of the forward horizontal stabiliser mount.
q
Attach the servo arm to the servo, making sure that it's centred and that the
pushrod is toward the
top
of the fuselage.
q
Slide the second piece of heat-shrink tubing over the end of the carbon
fibre pushrod, then attach the second piece of wire to the
middle hole
in the
control horn, using one snap-keeper.
q
Centre both the elevator servo and the elevator, then slide the heat-shrink
tubing over the wire.
q
Double-check that both the elevator servo and the elevator are still
centred, then use a heat-gun to shrink the heat-shrink tubing.
pro Tip
Place a piece of tinfoil between the pushrod and the aircraft to
prevent the heat gun from damaging the foam.
TIPS FRoM THE PRoS - AND A WARNING ABoUT GLUING FoAM
l
The Wingsail EP is constructed of foam. To make assembly quicker and easier, we suggest using Foam-Friendly C/A and
Foam-Friendly C/A "Kicker".
You MUST USE FoAM-FRIENDLY C/A
AND
FoAM-FRIENDLY C/A "KICKER". If you use C/A and
C/A "Kicker" that is not foam-friendly, the C/A will melt the foam and destroy the parts.
l
When applying clear tape to the airframe (to hinge the elevator and rudder, for example), you must not lift the tape back up or the
printed graphics will be pulled away from the foam. Do not use masking tape to hold parts in place.
l
Make sure to test-fit the parts together before applying glue. This will ensure that the parts fit properly before gluing them together.
l
We do not suggest storing your aircraft in an extremely hot environment (like the back of your car in direct sunlight) for any length
of time. The extreme heat could damage the foam parts and possibly damage the fragile components of the radio control system or
LiPO battery.
l
When gluing anything that has a smooth surface, it's important to lightly roughen the gluing surfaces with 220 grit sandpaper. This
will allow the glue to stick better. This is not necessary when gluing to foam.
l
Make sure to use high-quality connectors between your ESC and your motor and battery, and to insulate solder joints with heat-shrink
tubing to prevent short circuits and corrosion.
STEP 1: INSTALLING THE MoToR
WINGSAIL EP FINAL ASSEMBLY
q
Slide your ESC into the bottom of the fuselage so that the three motor plugs
pass through the lightening hole at the firewall.
q
Connect the three plugs from your motor to the three ESC motor plugs.
imporTanT
If the plugs on your motor do not match the motor plugs on your ESC, you'll need to solder compatible connectors in
their place. If you use the KMS motor and ESC that is recommended, the plugs will be compatible and no soldering is required.
q
Mount your motor to the firewall, using the wood screws provided. If you're
using the KMS motor that is recommended, the motor backplate should line
up diagonally with two of the pilot holes.
imporTanT
If the holes in your motor don't line up with the predrilled holes
in the firewall, you will need to drill new pilot holes in the firewall to match.
You may also need to use smaller diameter wood screws (not included) if the
wood screws provided are too large to fit through your motor backplate.
STEP 2: INSTALLING THE HoRIzoNTAL STABILISER SUPPoRT
q
Cut away the elevator from the horizontal stabiliser and set it aside for now.
q
Cut the strip of carbon fibre to a length of 368mm (14-1/2"), then place the
strip of carbon fibre into the precut slot in the stabiliser.
q
While holding the stabiliser down flat, apply a strip of clear tape (not included)
over the top and the bottom of the strip of carbon fibre to hold it in place.
