Safety precautions
Follow all instructions in this manual to assure safe operation.
If you have not assembled and operated a radio controlled model before, obtain help from an
experienced modeler. You will need guidance to successfully assemble, test and operate radio
controlled models. One of the best ways to obtain help is to join your local radio control club.
In some areas of the country, you cannot legally operate radio controlled models except at
approved fields. Check with local authorities first.
Observe frequency control. If someone else is operating a radio controlled model on the same
channel as your transmitter, do not turn on your transmitter—even for a short time. Your
transmitter has a channel number marked somewhere on its case. When a model receives
signals from two transmitters on the same channel at the same time, it cannot be con-
trolled and will crash—possibly causing personal injury or property damage. For safety,
most RC flying fields have formal frequency control rules. Follow them carefully.
Do not operate your radio control transmitter within 3 miles of a flying field. Even at a dis-
tance, your transmitter can cause interference.
