The horizontal stabilisers are pretty much completed for you at the
factory. The dual elevator control horns are pre fitted, and the stab
tube is already set up and ready to go! You will need to trim the
4mm brass hinge tube to the correct length, and install your choice
of servo.
Fitting the hinge tube is quite simple, just mark and trim the brass
tube to the required length. You can use tape to prevent the tube
from shifting position. Or you can use a small 4mm plastic plug like
those used in home reticulation systems. A 4mm sealing plug is
ideal, just remove the barb end with an X-Acto knife then push the
plug snugly into place. You will need to trim a little extra from the
brass hinge tube to accommodate the 4mm insert plug.
In the parts bag supplied you will find 2.9mm x 13mm pan head
sheet metal screw to mount your servos. It’s important that you
do
not
use the mounting screws supplied with your servo. The
mounting rib that is pre installed in the stabiliser has the mounting
holes pre drilled for you and the standard servo mount screws are
unsuitable. Some brands of servos use mounting eyelets that are
too small for the 2.9mm screws. You will need to change these if
necessary. Use JR standard servo eyelets.
A servo arm exit slot has been pre milled at the factory. This is
only a preliminary slot, you will need to enlarge the area required
to suit your servo and servo arm. This process is quite straight
forward, but make sure you measure twice and cut once! Mask off
the area around the pre milled servo arm exit slot. Locate the
servo mounting rib and mark this on the stab. It’s easy to locate,
using a small steel rule to measure the distance from the rib to the
slot, you will be able to see the rule through the exit slot. The
mounting rib is fitted 90° to the trailing edge. Use a square to
mark your lines.
The area marked out in the picture refers to a standard size servo,
as all servo and servo arms vary in size. Please take the time to
