• Fly only at approved flying fields and obey field regulations.
• Follow frequency control procedures. Interference can be dangerous to all.
• Obtain assistance from experienced pilots.
• The Guidance provided by experienced pilots is valuable and sometimes necessary.
• Know your radio. Check all transmitter functions before each flight.
• Be aware that rotating blades are very dangerous and can cause serious injury.
• Never fly near or above spectators or other modelers.
• Do not fly r/c helicopter models near buildings, high voltage cables, trees or other obstacles.
• If a beginner, get help trimming the model first and flight training later.

When first opening your Atom kit, you will notice that all of the parts are packaged and numbered to coordinate with the
assembly step numbers of this instruction manual. All small hardware (nuts, bolts, washers, etc.) for each step are packaged
separately within the main parts bags. When beginning a section, you will need to open only the bag with the corresponding
number to the section you are about to start. It is suggested that you place all of the hardware in an open container (e.g., servo
case) during assembly so as not to lose any of the small parts. It may also be helpful to familiarize yourself with the various
sizes of screws, bolts, nuts, etc., as illustrated in the appropriate assembly section before you begin assembly. In most cases, at
the end of each assembly section, there should be no parts remaining. Great care has been taken in filling the bags with the
correct quantity of parts and hardware for each section. However, occasional mistakes happen. In the event that you find a
parts shortage or are in need of technical assistance, please contact your local Compass Model parts dealer.
