Step. 3 Check trims and sub trims are set to neutral and controls centered.
Check rate and flight mode switches set properly.
If you are using MHz radio check the receiver antenna is fully extended and
not reversed on it self. Always double check to make sure your transmitter
antenna is fully extended.
Step. 4 If you are using any MHz radio you need to make sure that your
frequency is free before turning on your radio. Follow your club's pre-flight
instructions for obtaining the frequency pin.
Step 5. With your radio system on, make sure the control surfaces are
moving correctly with each stick movement of the transmitter. Ensure all
flight controls are free from binding and are centered. Check that all hinges
are tight and will not pull out. Control linkages must be rigid and tight and
have no slop.
Step 6. The engine vibrations during flight sometimes cause bolts to vibrate
loose. Make sure the bolts holding the wing to the fuselage are in place and
are tight. Make sure all engine mounting bolts and servo screws are tight.
Also make sure the propeller nut is tight. Check all control horn bolts, wheel
collars are tight and secure. Use Thread Locker where necessary.
Step 7. A range check is a very important pre-flight check that should be
done before the first flight of each day at the flying field. Do a range check
in accordance with the radio manufacturer instructions. If there is
insufficient range or interference do not fly until it is resolved.
Step 8. Hold onto the airplane and move the throttle stick forward. Verify
that the motor turns the right direction and goes to full throttle. Move the
throttle stick back to low, verify that the motor stops turning. Do not fly an
unreliable engine.
Step 9. Go fly and have some fun
