Before flying the model
Find a suitable flying site
Perform the range check for your plane
Monitor your flight time
Find a flying site clear of buildings, trees, power lines and other obstructions. Until you know how much area
will be required and have mastered flying your plane in confined spaces, choose a site which is at least the
size of two to three football fields - a flying field specifically for R/C planes is best. Never fly near people -
especially children, who can wander unpredictably.
As a precaution, an operational ground range test should be performed before the first flight each time you go
out. Performing a range test is a good way to detect problems that could cause loss of control such as low
batteries, defective or damaged radio components, or radio interference. This usually requires an assistant
and should be done at the actual flying site you will be using.
First turn on the transmitter, then install a fully-charged battery into the fuselage. Connect the battery and
install the hatch.
Remember, use care not to bump the throttle stick. Otherwise, the propeller/fan will turn and possibly cause
damage or injury.
Note: Please refer to your Transmitter Manual that came with your radio control system to perform a ground
range check. If the controls are not working correctly or if anything seems wrong, do not fly the model until
you correct the problem. Make certain all the servo wires are securely connected to the receiver and the
transmitter batteries have a good connection.
Monitor and limit your flight time using a timer (such as on a wristwatch or in your transmitter if available).
When the batteries are getting low you will usually notice a performance drop before the ESC cuts off motor
power, so when the plane starts flying slower you should land. Often (but not always) power can be briefly
restored after the motor cuts off by holding the throttle stick all the way down for a few seconds.
To avoid an unexpected dead-stick landing on your first flight, set your timer to a conservative 4 minutes.
When your alarm sounds you should land right away.
