7)Weight balance
Weighing operation must be done with 3 similar weighing machines on an horizontal
surface.
CG=146xA/A+B+C
The result must be located between 4,5 and 18
8) Preflight checks:
When you are all done, sit in the cockpit, and make sure the control-to-control surfaces system works per-
fectly, and gives the right responses; this is nothing but vital common sense: it is no fun to find out during your
first fly-around that the rudder cables have not been crossed. Some pilots never got over the surprise.
So it’s imperative to make all the following controls:
- Stick back => elevator up
- Stick forward => elevator down
- Stick left => left aileron up and right aileron down
- Stick right => right aileron up and left aileron down
- Push right foot => rudder right
- Push left foot => rudder left
Notice: during the first10 minutes of engine work, some particles coming from storage oil, can be blown out by
the exhaust muffler. To avoid the stain of the cloth, it is recommended to cover parts of the aircraft risking to be
touched.
Use only sweet soap and fresh water to clean the fabric.
