The 4-Servo rudder setup is
also a quickly removable
unit, to make service and
adjustment easy. It will
accept JR 8411 servos or
any other brand.
Complete hardware is
included. It is important, as
usual, that the servos are
centered BEFORE the horns
get finally mounted.
This rudder setup is not a
100% closed system.
Basically it is a system of 2
servos, which are coupled
by the 2 long all threads and
the 4 ball links. This setup
is sufficient when you use
the Volz Alustar Digital
servos. On top of that main
drive, both servos get a
coupling to another backup
servo, which is connected to
the main disk of each main
servo.
But, and this is important,
these 2 backup servos are
NOT connected with each
other. This allows a better
fine tuning for centering.
Start with screwing the 4
servos into the phenolic
servo tray. Insert the rubber
soft mounts into the slots of
the servo tray, and check
that they match the holes in
the fuselage board.
