Composite-ARF SuperXtra 330L (3.1m span)
The Stabilisers:
The stab parts are also vacuum bagged sandwiched. The
rudder and elevator control surfaces are hinged with 4mm
Ø tubes, fitted through phenolic hinge bearing plates which
are installed during manufacture for perfect alignment.
All the structural parts are pre-installed. The horizontal
stabs are mounted with one 20mm tube and a carbon rod
anti-rotation pin each. The rudder & elevator design allows
for at least 50 degrees throw. For the SuperXtra it is neces-
sary to keep the tail area as lightweight as possible, but it is
still mandatory that each stab is fitted with two powerful dig-
ital servos (JR8411 or 8511/8611) installed in each half.
Please remember during assembly that every gram of
weight should be saved in the tail area, without omitting our
recommendations about mass-balancing of the elevators.
Servo Screws:
Fix the all the servos into the milled plywood servo mounts
using the 2.9 Ø x13mm sheet metal screws provided in
the kit, not the standard screws normally supplied with
servos by the servo manufacturer. This is because all the
holes in our milled servo mounts are 2mm diameter, due
to our CNC manufacturing process, and this is too big for
the normal screws.
Take Care:
Composite sandwich parts are extremely strong, but frag-
ile at the same time. Always keep in mind that these con-
test airplanes are designed for minimum weight and max-
imum strength in flight. Please take care of it, especially
when it is being transported, to make sure that none of the
critical parts and linkages are damaged. Always handle
your airplane with great care, especially on
the ground and during transport, so you will
have many hours of pleasure with it.
