Hyperion BF109 25e Quick Start Manual

Before beginning construction please carefully read the following safety notes.
• The Hyperion BF109 is a fast and highly maneuverable airplane. It is NOT intended for beginners.
However, anyone with experience building and flying a few models, including one with aileron control,
will be able to master the BF109. We strongly suggest setting transmitter dual rate low switches to
60% of recommended throws for aileron and elevator for the first few flights. If you have any worry
about the first flight, don't hesitate to ask an experienced modeler to check the model setup and test
fly the model for you.
• Never fly a model airplane without a current membership in the R/C organizing body in your country.
That may be the AMA in the USA, or the FAI in many other countries. Membership should include
liability insurance. Check to be sure that you have it.
• Always check your flying field to be sure that it is safe before launching your model. Do not fly where
others, especially children, may come into the flight path without your notice, such as a public park.
• Be sure that your transmitter, receiver, batteries, and servos are in good condition before every flight.
Check carefully to see that no one else is using your frequency near your flying site.
• Many crashes are due to poor connectors or improper soldering between battery and ESC, or ESC and
Motor. Experienced builders: Don't let pride stop you from checking to be sure that EVERY solder joint
is good. Re-solder with a HOT iron if you have any doubts. Use only quality gold-plated connectors.
• Test motor/controller/battery setup without propeller attached first. When propeller is attached and
battery is connected, be sure that the model is restrained at all times. Never put any part of your body
in front of a spinning propeller.
• ALWAYS do a range test before first flight. See your radio manufacturer's recommendations for proper
range testing. If none is given, use the following: With antenna DOWN, range should be at least 25M
(80') before servos jitter. With antenna UP, 100M minimum (330'). Two tests should be performed,
one with the motor on and one with the power off. The range with the power on should be no less than
90% of the range with power off! When flying, keep your transmitter antenna pointed near vertical;
never point it directly at the model.
