l
Completely charge the transmitter and receiver batteries before your rst day of ying.
l
Check every bolt and every glue joint in the aircraft to ensure that everything is tight and well-bonded. This should include all of the
control surface hinges as well.
l
Double-check that you've installed and tightened all of the servo horn retaining screws.
l
Use thread locking compound on all fasteners that thread into metal to prevent vibration from loosening them.
l
Double-check that the receiver and battery are properly secured into the fuselage. There's nothing worse than the battery pack coming
loose during ight.
l
Double-check that the fuel tank is properly secured into the fuselage.
l
Double-check the balance of the aircraft. Do this with the fuel tank empty.
l
Check the control surfaces. They should all move in the correct direction and not bind.
l
Make sure that you've installed heat-shrink tubing over the clevises to prevent any chance of them opening during ight.
l
When installing the wing panels, double-check that the retaining clips are fully seated.
l
Make sure that you've sealed the aileron and elevator hinge gaps. Not sealing the aileron and elevator hinge gaps can lead to control
surface utter.
l
Double-check that the hex nuts (retaining nuts) are tightened against the clevises.
l
If your radio transmitter is equipped with dual rate switches, double-check that they are on the low-rate setting for your rst few ights.
l
Check to ensure that all of the control surfaces are moving the proper amount in both low and high rate settings.
l
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.
l
If you're using a 2.4GHz radio control system, refer to your radio control system's User's Guide for information on correct antenna
placement.
l
Properly balance the propeller. A propeller that is out of balance will cause excessive vibration, which could lead to engine and/or
airframe failure, and it will reduce engine efciency and power.
l
Double-check that the propeller nut(s) is/are tightened securely and that the spinner cone retaining screws are tight.
l
Double-check that no part of the spinner touches the propeller. You may need to enlarge the spinner cutouts to t.
The following are our general guidelines for your safety and the safety of others. Please read and understand these safety
l
Do not test-y your model for the rst time without rst having it safety-checked by an experienced modeler.
l
Do not y your model higher than approximately 400 feet within 3 miles of an airport without having an observer with you. The
observer should tell you about any full-size aircraft in your vicinity and you should always give the right-of-way to full-scale aircraft.
l
When ying at a ying eld with established rules, you should abide by those rules. You should not deliberately y your model in a
reckless and/or dangerous manner.
l
While ying, you should not deliberately y behind the ight line. If your model should inadvertently y behind the ight line, you should
change course immediately.
l
You should complete a successful range check of your radio equipment prior to each new day of ying, or prior to the rst ight of a
new or repaired model.
l
You should perform your initial turn after take- off away from the ight line and/or spectator area.
l
You should not knowingly operate your R/C radio system within 3 miles of a preexisting model club ying eld without a frequency
sharing agreement with that club.
