are a number of items or accessories that you may require after your initial
purchase. We have listed some of the more common items available.
To Know About Radio Accessories
The Servo extension is a cable with connectors on either end which goes
between the receiver and a servo. This allows the servo to be placed at
a greater distance from the receiver than the cable that comes on the
servo will allow. It also allows easier removal of a wing when the servo
that controls the aileron is mounted in the wing and the receiver is in
the fuselage (which is usually the case). Servo Extensions of various
lengths are available from different manufacturers. Long aileron extensions
can sometimes cause radio interference problems unless "noise traps" are
Dual Aileron Extension
The Y-Lead is a cable which plugs into a single channel in a receiver
and two servos. This allows both servos to be operated from the same channel.
A Noise Trap is a small electronic device which is wired into a long servo
extension to reduce radio interference and to boost the control signal
going to the servo. These are recommended for use where long servo leads
The switch harness is mounted in your model and it connected between your
receiver and the NiCad battery pack. It provides a power ON/OFF switch
to the radio in your model and it also allows your charger to be connected
to your model's battery pack for charging.
The frequency flag is a marker that is mounted on your transmitter to
indicate what frequency your system is operating on to alert other modelers
so as not to cause interference.
A Servo Tray is a plastic tray which allows easy mounting of your servos
in your model. The tray is moulded to hold your servos securely and ensure
positive control to your control surfaces. Different trays may hold anywhere
from one to four servos and are shaped for different uses and servo positions
in your model.
Servo Output Arms
Servo Output Arms are the plastic output horns which are mounted to the
output shaft on your servos. These come in various sizes for different
control uses. Most servos will come with an assortment of arms so you
can choose the arm to meet your own specific control needs.
