to extend the length. Avoid plugging multiple extensions together to obtain your desired
length. If the distance is greater than 50cm or high current draw servos are being used, use
heavy servo extensions.
• Receiver Vibration and Waterproofing: the receiver contains precision electronic part.Be
sure to avoid vibration,shock,and temperature extremes.For protection, wrap the receiver in
foam rubber or other vibration-absorbing materials. It is also a good idea to waterproof the
receiver by placing it in a plastic bag and securing the open end of the bag with a rubber band
before wrapping it with foam rubber. If you accidentally get moisture or fuel inside the
receiver,you may experience intermittent operation or a crash. If in doubt, please contact
Radiolink after-sales or distributors for service.
• Always mount the servos with the supplied rubber grommets. Don’t over tighten the screws.
No part of the servo casing should contact the mounting rails, servo tray or any part of
structure. Otherwise vibration will be transmitted to the servo causing damage of servo. Note
the small numbers (1,2,3,4) molded into each arm on the servo arms. The number indicate
how many degrees each arm is ‘off’ from 90 degrees to correct for minute manufacturing
deviations from servo to servo.
To center the servos, connect them to receiver and turn on the transmitter and receiver. Center
the trims on the transmitter, then find the arm that will be perpendicular to the push rod when
placed on the servo.
After the servos are installed, operate each servo over its full travel and check that the push
rods and servo arms don’t bind or contact each other. Also make sure the controls do not
require excess force to operate. If there is an objectionable buzzing sound coming from a
servo, there is probably too much resistance in the control. Find and correct the problem.
Even there is no servo damage, excess battery drain will result.
•Use the mouthing plate from the receiver on/off switch as a template for the cutout and screw
holes, mount the switch on the side of the fuselage opposite the engine exhaust, and where it
won’t be inadvertently turned on or off during handling or storage. Be certain the switch
moves without restriction and ‘snaps’ from ON to OFF, and that the cutout allows full motion
