Safety Do's and Don'ts for Pilots

● Ensure that your batteries have been properly
charged prior to your initial flight.
● Keep track of the time the system is turned on so
you will know how long you can safely operate your
system.
● Perform a ground range check prior to the initial
flight of the day. See the "Daily Flight Checks
Section" for information.
● Check all control surfaces prior to each takeoff.
● Do not fly your model near spectators, parking
areas or any other area that could result in injury to
people or damage of property.
● Do not fly during adverse weather conditions. Poor
visibility can cause disorientation and loss of control
of your aircraft. Strong winds can cause similar
problems.
● Do not point the transmitter antenna directly toward
the model. The radiation pattern from the tip of the
antenna is inherently low.
● Do not take chances. If at any time during flight
you observe any erratic or abnormal operation, land
immediately and do not resume flight until the
cause of the problem has been ascertained and
corrected. Safety can never be taken lightly.

Dual Rate Recommendations
● We recommend that the rudder dual rate be set to
Low for takeoff to help minimize overcorrection
during the takeoff roll.
● We recommend the rudder dual rate be set to High
for landing to help maintain heading as the model
transitions from flying speed to taxi speeds.
● Elevator and Aileron dual rates should be adjusted
for personal feel and also if there are any unusual
wind conditions.

Age Requirements

Age Recommendation: 14 years or over. This is not
a toy. This product is not intended for use by children
without direct adult supervision.

Daily Flight Checks

Step 1
Check the battery voltage on both the transmitter and
the receiver battery packs. Do not fly below 9.5V on
the transmitter if you are using a JR or Spektrum
transmitter that uses 8-cells to power the transmitter.
Do not fly if the receiver pack is at or below 4.7V. To
do so can crash your aircraft.
Note:When you check these batteries, ensure that
you have the polarity correct on your expanded scale
voltmeter.
Step 2
Check all hardware (linkages, screws, nuts, and bolts)
prior to each days flight. Be sure that binding does not
occur and that all parts are properly secured.
Step 3
Ensure that all surfaces are moving in the proper
manner.
Step 4
Perform a ground range check before each flying
session.
Step 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.
Step 6
Check that all trim levers are in the proper location.
Step 7
All servo pigtails and switch harness plugs should be
secured in the receiver. Make sure that the switch
moves freely in both directions.
