●
Cycle the flight battery three times. When NiMH or NiCD batteries are new they need to be used 2-3 times before
they will produce their top voltage and duration. To cycle them, simply charge the battery and then run the motor (at
low speed to prevent damaging it) until the motor stops. Allow the battery and motor to cool, then repeat this
procedure two more times.
●
Check the condition of the transmitter batteries. They should be fully charged.
●
Check every bolt and every glue joint in the airplane to ensure that everything is tight and well-bonded.
●
Double-check that all of the control horns are tight.
●
Double-check the balance of the airplane.
Do this with the flight battery installed.
●
Check the control surfaces. They should all move in the correct direction and not bind.
●
If your radio transmitter is equipped with dual rate switches, double-check that they are on the low-rate setting for
your first few flights.
●
Check to ensure that all of the control surfaces are moving the proper amount in both low and high rate settings.
●
Check the receiver antenna. It should be fully extended and secured firmly to the bottom of the wing.
●
Double-check the wiring of the motor and the propeller. Because the motor is installed in a pusher configuration, the
motor should be wired backwards and the propeller should be installed backwards. If not, there will be limited forward
thrust produced by the power system and the airplane will not fly.

Before your first flight, take a moment to double-check the following points:
●
Carefully double-check the balance of the airplane. The balance point is located 6-1/8" behind the leading edge of the
wing, measured at the centerline.
●
Double-check that both elevons are centered, as described in section 10.
●
Double-check that the elevons are moving in the proper direction both up and down and right and left.
●
Double-check that the control throws are set correctly, as described in section 10.
●
Double-check that the power system is providing full thrust. At full power, the airplane should feel like it's pulling out of
your hand.
Hand-launching should always be done into the wind.
To hand-launch the airplane, gently grasp the hand-launch fairing between your thumb and forefingers. Hold the airplane
above shoulder level and turn on the motor to full power. With the motor running at full power, firmly toss the airplane
straight ahead and level. Do not throw it up at an angle or throw it too hard. Allow the airplane to fly straight and level to
pick up airspeed, then climb to your desired altitude. Be careful not to climb too steeply after hand-launching or you could
stall the airplane.
