Composite-ARF SPARK
When the canopy is tacked into the frame, and it
cannot twist any more, you can carefully remove
the compete canopy frame and secure the
inside edge of the clear canopy with a small
bead of slow (24hr) epoxy and microballoons.
Alternatively you can use a specialist canopy
glue that dries clear and bonds well the the clear
plastic. Whichever method you chose, make
sure to secure the canopy frame in it's final posi-
tion on the fuselage while the glue dries to
ensure that nothing can deform.
* Please see page 29 of these instructions for
details of cutting the cooling inlet slots and
installing the baffle for the speed-controller.
Fuselage
We recommend that you complete the remain-
der of the fuselage assembly and R/C installa-
tion in the order shown below.
Cable Duct:
Make the route for the extension leads and air
tubes from the wing by trimming away the flanges on the
inside of the inlet ducts, behind the plywood bulkhead - leav-
ing approx. 5mm width for strength, and protecting the
edges. Split the length of silicone tube (included in the hard-
ware) with a sharp knife, and glue it on to the remaining nar-
row flange with a little thin CA, as shown here.
Nosegear
The factory-installed nosegear bulkhead is 6mm thick lami-
nated aircraft-grade plywood, with the mounting holes pre-
drilled and the M3 T-nuts glued to the front face of it. The
hole centres match the Spring-Air 301 series 'Firewall'
mount, and if you chose to fit a different retract unit then you
will need to push out the T-nuts and redrill to suit the mount-
ing centres of your nose unit.
Assemble the nose retract unit as shown, with the steering

epoxy/micro-balloons mixture. Also note the
short tube that accepts the nose fixing wire.
Make sure that this is securely glued in place !

split silicone tube to protect extension wires
and air lines from sharp edges.
