Radio Control Equipment Installation.

Fuselage servo installation
Install the rudder & elevator servos in the cut-outs in the servo mounting frame according to
the instructions supplied with the servos. Fit clevises and lock-nuts and adjust accordingly
such that the control surfaces are held at neutral when the servo positions are centred and
make maximum use of the servo throw. Check the operation to ensure smooth running and
slop free control linkages always keeping mind to minimise the length of unsupported control
linkages.
Wing servo installation
The servos themselves are simply bonded to the inside of the servo cover scoop using
suitably thickened epoxy and screwed onto the plywood frames (see also the installation
note supplied with the TA servo LOCK set). Be sure to roughen the surface of the servo
cover to ensure a good bond.
Tip: Most model pilots will have their own preferred means of securing the wing servos.
However, one popular method is to protect the servo in heat-shrink tubing and then secure
using epoxy resin. A good quality (aquarium grade) silicone sealant can also be used.
However you choose to proceed, make sure that the servos are firmly attached to the
servo covers.
Ensure that the servo output arms are set at 90° with the servo electrically centred. Prepare
the linkages, using threaded rod, clevises and lock-nuts remembering to apply a drop of
thread-lock to the lock nuts or apply a short length of heat-shrink over the joint.
Secure the servo covers in place using the four small screws provided. Use a countersink
tool to recess the screw heads into the servo covers to improve both the appearance and the
aerodynamic performance.
Receiver Battery (*)
In the case of the pure glider, mount the receiver battery on the servo mounting tray as far
forward in the nose as possible.
In the case of the electric powered glider, the receiver battery is best mounted on the servo
mounting tray in a position behind the servos.
Receiver installation
The receiver itself is best installed on the servo mounting tray; a good quality Velcro hook &
loop material is quite adequate for this purpose. The receiver antenna is ideally inserted into
a suitable antenna tube (or plastic Bowden tube) and inserted down the length of the
fuselage
Although there is a certain amount of Carbon used in the construction of the fuselage, we
would suggest that there is no problem running the antenna down the inside of the fuselage
boom (we fly all our models this way). However, ALWAYS carry out a thorough range test
before flying the model and if any doubt whatsoever then allow the antenna to hang freely.
Tip: Never install the antenna taut, but allow some slack in the wire to allow for small
movements within the fuselage.
