e) Installing the Rudder Linkages
Mount the two clevises to the threaded connec-
tions of the elevator and rudder rods (figure 8,
items 1 and 3) so that about 50% of the thread
is screwed into the clevises.
Shorten the Bowden tubes at the tail as shown
in figure 8, items 2 and 4, so that approx.
30 mm of the pushrod has no Bowden tube.
Clip the clevises to the outer-most holes of the
rudder horns of the elevator and rudder.
Connect the servos to the remote control and
put the servos at the transmitter in the neutral
position.
Mount one rod connection (7) each to the rud-
der horns of the servos.
Attach the rudder horns to the servo so that the-
re is a right angle between the rudder horn and
pushrod. Secure the rudder horn at the servo
again with the intended screw.
Push the pushrods from the Bowden tubes (8) into the linkage connectors of the servo (7).
Shorten the pushrods with the elevator or rudder flap in the neutral position so that you can fasten the rods at the
servo rudder horns with a protrusion of approx. 10 mm. Attach the thrust rods to the linkage connections with the
hexagon socket screws.
Perform a function test with the remote control transmitter. If the rudder control works properly, you can switch off the
remote control again.
f) Cooling of Motor, Flight Controller and Flight Battery
The motor with flight controller and flight bat-
ters grow hot in operation and therefore require
forced cooling.
For this, a cooling air hole must be applied by
cutting open the iron-on foil at the top of the
fuselage and air intakes (2) must be installed.
The air intakes must be cut out of a plastic for-
med part with a little protrusion. Glue the air in-
takes to the fuselage with 5-minute epoxy resin
as shown in figure 9, item 2.
