FUTABA 6EXHP Instruction Manual page 6

• After the servos are installed, operate each servo over its full travel and check that the pushrods and servo arms do not
bind or contact each other. Also make sure the controls do not require excess force to operate. If there is an objectionable
buzzing sound coming from a servo, there is probably too much resistance in the control. Find and correct the problem.
Even if there is no servo damage, excess battery drain will result.
• When you install the switch harness to the helicopter, please use switch cover. Generally sandwich the frame by switch and
switch cover and securely tighten the screws. It might be different installations on model by model. In that case, please
follow the model instruction manual.
• 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 23).
External antenna mounting:
• 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.
