The 4mm hole in the upper left side frame
is thought for (later) mounting the servo
arm on the elavator servo.
Rough length of the three linkages of the
swashplates servos (Futaba BLS 471).
Push the ball joints for the roll servo linka-
ges with the number outside on the servo
arms and on the joint bolts of the swash-
plate. Check that the ball joints are moving
free on the balls. If not press gently with
an old pliers in mounted condition on the
outside of the ball joints until they become
a bit looser. This procedure is shown later
for the tail pitch slider (bag 10).
The roll servo arms and the elevator servo
arm are attached with a hex bolt M3x8
D197 and a washer shim 3x6x1 051 using
Loctite. This step should be done later
when electric current is on the servos and
they have their real center position.
