BALANCE POINT:
the Center of gravity (C/g or balance point) is 1" (25mm) back from the leading edge of the
CENTER

, measured at
the middle of the wing.
Ailerons: 1/2" (13mm) up & Down
elevator: 5/8" (15mm) up & Down
rudder:
3/4" (19mm) right & left
THE CONTROL THROWS ARE MEASURED FROM THE WIDEST POINT OF THE CONTROL SURFACES
These control throws are a good starting point. once you become more familiar with the flight characteristics of the airplane,
you can increase the control throws a little bit at a time until you're satisfied with the result.
WARNING
Do not balance the airplane further back than recommended or the airplane will be very difficult to control, especially
in pitch. An uncontrollable crash could result!

●
Check the operation of the throttle. To do this, do the following:
A) Plug the flight battery into the ESC and turn on the radio system.
B) When the throttle control stick is at the idle position, the motor should be off. Moving the stick forward should turn on the
motor. Gradually moving the stick to the full forward position should result in the motor running at full power.
☞
If you're using a computer radio, you may need to increase your throttle channel's EPA setting to result in full power. (Refer to
your radio system's operating guide for further information.)
●
Check the condition of the transmitter batteries. They should be fully charged.
●
Check every glue joint in the airplane to ensure that everything is tight and well-bonded.
●
Double-check that you've installed and tightened all of the servo horn retaining screws.
●
Double-check that the battery is properly secured into place. There's nothing worse than the battery coming loose during flight.
●
Double-check the balance of the airplane.
Do this with the battery installed and the airplane ready to fly.
●
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 not coiled up. Do not cut the receiver antenna shorter or the range of
your radio control system will be greatly reduced.
●
You should complete a successful range check of your radio equipment prior to each new day of flying, or prior to the first flight of
a new or repaired model.
●
You should not knowingly operate your R/C radio system within 3 miles of a preexisting model club flying field without a frequency
sharing agreement with that club.
WARNING
Do not turn the receiver on unless the transmitter is turned on first. Always turn the transmitter on first. Never allow
hands or clothing to get in the way of the propeller when the radio is turned on. Sudden unwanted radio signals, or turning the radio
on with the throttle stick set at full throttle, can turn the motor on unintentionally. Always make sure that the throttle control stick is
set to idle before turning on the transmitter.
