SECTION 17: PREFLIGHT CHECK AND SAFETY
●
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.

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.
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.
●
Completely charge the transmitter and receiver batteries before your first day of flying.
●
Check every bolt and every glue joint in the airplane to ensure that everything is tight and well-bonded. This should
include all of the control surface hinges as well.
●
Double-check that you've installed and tightened all of the servo horn retaining screws.
●
Double-check that the flight battery is properly secured into the fuselage.
●
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 not coiled up inside the fuselage. 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 perform your initial turn after take- off away from the flightline and/or spectator area.
●
When flying at a flying field with established rules, you should abide by those rules. You should not deliberately fly your model
in a reckless and/or dangerous manner.
●
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.
SECTION 16: CONTROL THROWS
The control throws listed in this section are for test-flying and general sport-flying. If you want the airplane to be more aerobatic and
responsive, we suggest increasing the control throws in small amounts until you find your desired settings.

The control throws are measured from the widest point of the control surfaces.

We do not suggest increasing the control throws beyond the recommended sport-flying settings unless
you are a proficient flyer. Higher control throws will cause the airplane to be extremely contol-sensitive and result in a possible
crash if you are not careful.
