If you are a beginning modeler and not yet a member of an R/C club, joining a club and flying at a site specifically intended for
R/C model aircraft is highly recommended highly recommended. In addition to joining a club, we strongly recommend joining the AMA (Academy
of Model Aeronautics). AMA membership is required to fly at AMA clubs. There are over 2,500 AMA-chartered clubs across
the country. Among other benefits, the AMA provides insurance to its members who fly at sanctioned sites and events.
Additionally, training programs and instructors are available at AMA club sites to help you get started the right way. Contact
the AMA at the address or toll-free phone number below:

IMPORTANT: IMPORTANT:
If you do insist on flying on your own, you must must be aware of your proximity to R/C club sites. If there is an R/C site within six
miles of where you are flying, and if you are operating your model on the same frequency as somebody else, there is a
strong strong possibility that one or both models will crash due to radio interference. There is great great potential for an out-of-control
model to cause property damage and/or severe personal injury. We strongly strongly urge you to fly at an R/C club site where
frequency control is in effect so you can be confident you will be the only one flying on your channel.
Charge the batteries Charge the batteries
Second to the pilot's flight skills, one of the most important factors that can determine a model ’ s longevity is the
state-of-charge of the batteries - especially the on-board receiver pack. Inadequate charging and failing to monitor a battery's
voltage may lead to low battery power, causing loss of control and a crash. To avoid this, always charge the batteries the night
before you go flying. If ever uncertain how much "charge" is left in a battery, it is wiser to err on the side of caution, rather than
trying to get in one last flight! Due to the number of factors that determine receiver battery power consumption (such as the
number and type of servos in your model, the type of flying you do, how much resistance is built into the controls, the size of
the model, etc.), it is not possible to recommend how many flights one can get on a charge. The best way to monitor battery
power and calculate how much flight time you have left is to use a volt meter to check the batteries after each flight. This can
be done through the battery charging plug coming from the switch. There are many small, hand-held volt meters available
specially intended for R/C use. The Hobbico ® Digital Voltmeter MKIII ™ (HCAP0356) is one such unit. An on-board volt meter
mounted directly on the model (HCAP0330) can also be used.
