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.
