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:
Protect the servos with heat shrink sleeve. This makes for easy removal and
replacement of the servo, but care should be taken so as not to overheat the servos
while applying the sleeve.
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
The receiver battery is positioned in the nose, forward of the servo mounting tray and must
be adequately secured for flight.
Receiver installation
The receiver itself is best installed on the servo mounting tray, to the rear of the fuselage
cockpit opening; a good quality Velcro hook & loop material is quite adequate for this
purpose.
Receiver Antenna
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.
The model is now largely complete, but some very important work remains to be done
while still in the workshop.
Balancing & Adjusting.
The correct centre of gravity and longitudinal dihedral are first determined theoretically, and
then confirmed in practice by test flying the model.
A successful first test flight is invariably a matter of good preparation!
