Horizontal Stabs
The stabs are 99 percent finished for
you at the factory and only require
little work to complete. The stabs
installed on the fuse using a 14mm
aluminum tube and two 3mm screws.
Be sure to note the tube is marked L
and R. A brass 4 mm tube is provided
and is used to install the elevators.
Cut the tube to size and install. The
tube can be held in place with a small
drop of epoxy or a small screw as
shown. Next we need to install the
elevator servos. We recommend a
high powered servo like a JR 8911HV
and aluminum servo arms like the
SWB’s shown. NOTE: Use the 3mm
screws provided with the kit to mount
the servo not the screws that come
with the servos. With the servo
installed as shown, center the servo
and install the servo arm. Use the
3mm threaded rod provided to make
up the linkage. It’s a good idea to
install a piece of 4mm brass tube over
the threaded rod for reinforcement.
We used titanium push rods.
Rudder
The rudder only requires installation
onto the Vertical Stab with a 4 mm
brass tube. Cut the provided tube to
length and install the rudder. Use a
small drop of epoxy and a small screw
to retain the tube. Use the cable
provided to make up two pull cables.
Two holes can be cut in the fuse as
shown. 9” from the back edge of the
fuse and 2” up from the bottom. We
used a small piece of antenna tube as
a guide for the cable through the fuse.
