6. Installation
!
Connect the servos, batteries and switch harness in accordance with fig 3. Carefully
check to ensure that all connectors are properly seated.
!
Turn the power switches "ON" and operate the transmitter. Observe the direction of travel
of the control surfaces to see if they correspond to the control stick movement. Improper
servo direction is corrected with the servo reverse dip switches, (fig 3)
!
Operate each servo over its entire range and check for binding of the push rods. Correct
as necessary. Hold each control stick at its extreme position and listen for servo hum. The
hum indicates that the control linkage is too tight for the amount of servo travel. This is
corrected with the end point adjustment or by lengthening the push rods.
!
Applying unreasonable force to a servo output arm will adversely affect the servo and
quickly drain the flight batteries. Therefore, all control linkages should operate as
smoothly and as frictionless as possible. Use Hitec "Jam Check'r" to assure smooth, safe
control setups.
!
When installing the switch, cut a rectangular hole somewhat larger than the full stroke of
the switch, then install the switch so it moves smoothly from ON to OFF.
!
The length of the receiver antenna is critical to the reception of signals transmitted,
therefore DO NOT cut or bundle the antenna wire, make every effort to keep the antenna
wire fully extended.
!
Protect the receiver from excessive vibration by wrapping it in sponge rubber (note: Use
Hitec "Flight Preserver : #8480"). Next place the receiver in a plastic bag. Secure the
plastic bag with rubber bands to keep out moisture and dust.
!
Collapse the transmitter antenna fully and operate the system from a distance of 60 to 90
feet. The system should function flawlessly. If it does not, check to see that the receiver
and transmitter batteries are at maximum capacity.
Charging Instructions
!
Before first use of Focus system, connect appropriate charge connectors from charger to
transmitter and receiver switch harness with battery connected.
!
With transmitter and receiver switched OFF, plug charger into 110-120V AC and be sure
the RED & GREEN charge lights are ON. If either charger light is OFF, re-check
connections to charger and be sure switches on transmitter and receiver are OFF.
!
Charge for 24 hours first before further use of system. This conditions the batteries for
full-charge capacity.
!
Re-charge 16-20 hours immediately before each flying day.
