For redundancy and flight safety each
taileron should be controlled by 2 servos.
To make the installation of the rods and
the adjustments of the servos easy please
use the included mounting jig which has
the same dimension as the servo mounts
in the fuselage. It is important to match
both servos extremely exact. Either with
your transmitter or even better, with a
matching device like PowerBox, JR Match
Box or Futaba MSA10.
Note: The neutral position of the elevator
servo arms is 15 degree forward!
The connection linkage between the two
servos should be installed at the 20 mm
holes. Start with 66 mm length and fine
tune VERY precisely so that the servo arms
are exactly parallel.
The distance for the actual elevator
pushrod from center axis is 33-35mm.
The length of the actual taileron pushrod
connection is 82mm hole-to-hole.
Obviously strong aluminium servo arms
have to be used!
