Please read and understand the following instructions for your
new radio system prior to operation to ensure the safest and
most enjoyable experience.
Features:
• Your model can cause serious damage or injury so please use caution and courtesy when operating your model.
• Do not expose the radio system to water or excessive moisture.
• As a safety precaution, perform all transmitter and receiver adjustments with the vehicle’s wheels off the ground. This ensures
the complete control over the vehicle at all times during adjustments.
• Ensure your batteries (both transmitter and vehicle) have been properly charged for use with your model.
• Keep track of the time the system is in use so you will know how long you can safely operate the transmitter batteries.
• Check all servos and electrical connections prior to each run.
• Do not operate your model near traffic, bystanders, parking areas, or any other area that could result in injury to people or dam-
age to property.
• If at any time during the operation of your model you observe any erratic or abnormal behavior of your model, immediately stop
operation and bring the mode to a safe stop in a safe location to diagnose the problem.
• Always power on your transmitter before turning your vehicle on.
• If you have little or no experience operating R/C models, we strongly recommend you seek the assistance of your local hobby
dealer.
R/C models are an extremely fun hobby, but safety should never be ignored or taken lightly. Always take caution when operating
your model as damage to property and injury can result from careless operation. Please consult your local hobby dealer with any
