This is a high-output, full-range radio control system that should well exceed the range needed for any surface model. For
safety, the user should perform a range test at the area of operation to ensure that the radio control system has complete
control of the model at the farthest reaches of the operational area. Rather than operating the model, we recommend that the
user enlist the help of a fellow modeler to walk the model to the farthest reaches of the track (or for boats, to walk the shore line
well in excess of the operational distance of the boat), then test for proper operation.
• Be certain to read this User's Guide in its entirety.
• 'Safety First' for yourself, others and your equipment.
• Observe all the rules of the field, track or lake where you operate your radio control equipment.
• If at any time during the operation of your Model, should you feel or observe erratic operation or abnormality, end your
operation as quickly and safely as possible. DO NOT operate your model again until you are certain the problem has been
corrected. TAKE NO CHANCES.
• Your model can cause serious damage or injury. Please use caution and courtesy at all times.
• Do not expose the radio control system to water or excessive moisture.
• Waterproof the receiver and servos by placing them in a water-tight radio box when operating R/C model boats.
• If you have little to no experience operating R/C models, we recommend you seek the assistance of an experienced
modeler or your local hobby shop for guidance.
• The Low Voltage Alert alarm will sound when the transmitter battery voltage drops to the default low voltage threshold. If this
occurs, stop using the transmitter as soon as is safely possible, then replace or recharge the transmitter batteries.
This radio control system operates on the 2.4GHz frequency band. The 2.4GHz connection is determined by the transmitter
and receiver pair. Unlike ordinary crystal-based systems, your model can be used without frequency control.
