Connector Connections
Servo Installation
Be sure the receiver, servo, battery and connectors are fully and firmly connected.
If vibration from the model causes a connector to work loose while the model is in operation, you may lose control .
When you install the servos, always use the rubber grommets provided in servo hardware bags.
Mount the servos so they do not directly come in contact with the mount.
If the servo case comes in direct contact with the mount, vibration will be directly transmitted to the servo.
If this condition continues for a long time, the servo may be damaged and control will be lost.
Servo Throw
Operate each servo over its full stroke and be sure the linkage does not bind or is loose.
The continuous application of unreasonable force to a servo may cause damage and excessive battery drain.
Screw
Mechanical plate
Nut (as required)
Eyelet
Damper
(or)
When installing the servo, always install the accessory
rubber grommet and grommet flush against the servo.
A vibration-damping effect is not obtained if
the rubber grommet and grommet are not in-
stalled correctly.
Adjust the throttle servo so that excessive force is not
applied when the engine carburetor is fully open, fully
closed, and the brakes are applied fully.
If the brakes overheat while running, their ability to
function properly decreases. Before running, adjust the
suitable maximum servo travel so that excessive force
is not applied even when the servo travel is increased
while running.
Adjust the steering servo so that excessive
force is not applied to the servo by the chas-
sis at maximum servo travel.
Decide the EPA value at the
contact point.
Caution!
A whining noise indicates that the
steering servo is improperly set.
