FCC Information
This device complies with part 15 of the FCC rules. Operation
is subject to the following two conditions: (1) This device may
not cause harmful interference, and (2) this device must accept
any interference received, including interference that may cause
undesired operation.
Caution
: Changes or modifications not expressly
approved by the party responsible for compliance could
void the user’s authority to operate the equipment.
This product contains a radio transmitter with wireless
technology which has been tested and found to
be compliant with the applicable regulations governing a radio
transmitter in the 2.400GHz to 2.4835GHz frequency range.
Daily Flight Checks
1. Check the battery voltage on both the transmitter and
the receiver battery packs. Do not fly below 9.0V on the
transmitter or below 4.7V on the receiver. To do so can
crash your aircraft.
Note
: When you check these batteries, ensure that
you have the polarities correct on your expanded scale
voltmeter.
2. Check all hardware (linkages, screws, nuts, and bolts) prior
to each day’s flight. Be sure that binding does not occur and
that all parts are properly secured.
3. Ensure that all surfaces are moving in the proper manner.
4. Perform a ground range check before each day’s flying
session.
5. Prior to starting your aircraft, turn off your transmitter, then
turn it back on. Do this each time you start your aircraft.
If any critical switches are on without your knowledge, the
transmitter alarm will warn you at this time.
6. Check that all trim levers are in the proper location.
7. All servo pigtails and switch harness plugs should be
secured in the receiver. Make sure that the switch harness
moves freely in both directions.
Servo Precautions
• Do not lubricate servo gears or motors.
• Do not overload retract servos during retracted or extended
conditions.Make sure they are able to travel their full
deflection. Overloading or stalling a servo can cause
excessive current drain.
• Make sure all servos move freely through their rotations
and no linkages hang up or bind. A binding control linkage
can cause a servo to draw excessive current. A stalled servo
can drain a battery pack in a matter of minutes.
• Correct any control surface “buzz” or “flutter” as soon as
it is noticed in flight, as this condition can destroy the
feedback potentiometer in the servo. It may be extremely
dangerous to ignore such “buzz” or “flutter.”
• Use the supplied rubber grommets and brass servo eyelets
when mounting your servos. Do not over-tighten the servo
mounting screws, as this negates the dampening effect of
the rubber grommets.
• Ensure the servo horn is securely fastened to the servo. Use
only the servo arm screws provided; the size is different
from other manufacturers.
• Discontinue to use servo arms when they become
“yellowed” or discolored. Such servo arms may be brittle
and can snap at any time, possibly causing the aircraft to
crash.
• Check all related mounting screws and linkages frequently.
Aircraft often vibrate, causing linkages and screws to
loosen.
General Notes
Radio controlled models are a great source of pleasure.
Unfortunately, they can also pose a potential hazard if not
operated and maintained properly.
It is imperative to install your radio control system correctly.
Additionally, your level of piloting competency must be high
enough to ensure that you are able to control your aircraft under
all conditions. If you are a newcomer to radio controlled flying,
please seek help from an experienced pilot or your local hobby
store.
