10. Pre-flight checks
When you have completed the model, run through the final checks listed below before carrying
out the helicopter’s first flight:
•
Study the manual once more, and ensure that all the steps of assembly have been carried
out correctly.
•
Check that all the screws in the ball-links and brackets are tightened fully after you have
adjusted gear meshing clearance.
•
Can all the servos move freely, without mechanical obstruction at any point? Do they all
rotate in the correct direction? Are the servo output arm retaining screws in place and tight?
•
Check the direction of effect of the gyro system.
•
Ensure that the transmitter and receiver batteries are fully charged. We recommend using a
voltage monitor module (e.g. Order No. 3157) to check the state of the receiver battery
when you are at the flying field.
Don’t attempt to start the turbine and fly the helicopter until you have successfully checked
everything as described above.
Bear in mind that the running qualities of your turbine will vary widely according to the height of
your flying site above sea level and atmospheric conditions.
Maintenance
Helicopters, whether large or small, place considerable demands on maintenance. Whenever
you notice vibration in your model, take immediate steps to reduce or eliminate it. Rotating
parts, important screwed joints, control linkages and linkage junctions should be checked before
every flight. If repairs become necessary, be sure to use original replacement parts exclusively.
Never attempt to repair damaged rotor blades; replace them with new ones.
