Step 7. Final check before flying
You have finished your model airplane, but you have to check before
flying.
1.
Check the alignment and trim of the airplane after final assembly.
2.
Check that everything is tightly securely.
3.
Check the C.G. point, which must be 83mm (3.27 in.) behind the
leading edge measured at the center of the upper wing center section.
In order to obtain the C.G specified, add weight to the fuselage or
move the battery position. Check the C.G. before flying.
4.
Make sure that the servos operate properly and the control surfaces
move in the correct direction.
5.
Make sure that the model is balanced laterally. Add weight to a wing
tip if necessary.
6.
The travel of each control surface depends upon your piloting skill
level and flying style. We recommend the following to begin with:
Elevator: 10 mm up/down
Rudder: 30 mm left/right
Ailerons: 5 mm up/down
7.
Radio and motor check as follows:
Antenna collapsed, transmitter and receiver switched off
Make sure that the throttle stick is at its lowest position
Turn on the transmitter first, and then the receiver.
Move the controls to make sure that they all function correctly
Walk away from your model for at least 100 feet (30 meters).
Slowly and steadily move the controls and have an assistant watch
for elevator, rudder, or ailerons flutter. Refrain from fast sharp
movements.
Repeat the same control check with the engine running at idle as
well as full throttle. This safety check may reveal a faulty receiver,
servo or wiring/switch problems which only occur with vibration.
Don’t forget to extend the antenna of your transmitter to its full
length before you start flying.
Make sure that nobody is using your frequency.
Good luck and happy flying!
