FUTABA 6EXP Instruction Manual page 9

• IMPORTANT: NEVER cut the receiver antenna or mount it in the model folded back on itself. Doing so will change its
electrical length, possibly reducing the distance from the pilot that the model can be controlled ("range").
• The receiver antenna may be mounted inside or outside the model:
Internal antenna mounting:
• You may run the antenna inside of a non-metallic housing within the fuselage, but range may suffer if the antenna is
located near metal or carbon fiber pushrods or cables. Do not bind the antenna with servos, switch, battery harnesses. Be
sure to perform a range check before flying (see page 35).
External antenna mounting:
• A. Use a cut off servo arm as a "stop" or strain
relief inside the fuselage to keep tension off the
solder joint holding the antenna to the receiver.
Guide the antenna through a hole in the fuselage. (If
possible, insulate the hole with a rubber grommet or a
small piece of rubber tubing.)
B. Make a hook from another cut off servo arm.
Insert the end of the antenna through two holes,
then connect the hook to a rubber band around a pin
inserted into the vertical stabilizer. Allow any excess
antenna length to trail behind the hook.
• Please use rubber grommet or silicon tube to protect from cut or peel off insulation of
antenna on the fuselage antenna-exiting hole.
Place the receiver antenna out from the fuselage part to the nonmetal tube installed
in skid etc. Please keep antenna away from parts that made of metal and carbon
graphite.
• The receiver contains precision electronic parts. It is the most delicate radio component on-board the model and should
be protected from vibration, shock and temperature extremes. To protect the receiver, wrap it in R/C foam rubber or other
vibration-absorbing material. If appropriate, waterproof the receiver by placing it in a plastic bag and closing the open end
with a rubber band before wrapping it in foam. If moisture enters the receiver, intermittent operation or a failure may result.
Wrapping the receiver in a plastic bag also protects it from fuel and exhaust residue which, in some models, can work its
way into the fuselage.
Mounting the frequency clip: (for USA)
• To announce your frequency and avoid potential interference problems, the frequency
number should always be displayed on the transmitter antenna while flying. Peel the
backing from the numbers and apply them to both sides of the clip. Snap the end of the clip
that fits best to the base of the antenna as shown. You may cut off the other end of the clip.
