The rudder tray provided is suitable for 2 servos. You may elect to
use 1 x 30kg plus servo. The servo tray is designed to fit into the
fuselage former at the beginning of the turtle deck. Before you
proceed, you should assemble the model, and do a preliminary C
of G check to make sure that you will meet the C of G
requirements. If the model is tail heavy now is the opportunity to
move the rudder tray further forward in the fuselage. If you do
need to move the rudder tray forward, you will need to make 2
new ply formers to attach to the existing rudder tray.
The supplied phenolic arms are required to be mounted onto alloy
servo discs.
DO NOT USE THE STD NYLON SERVO DISCS!
The standard discs provided with the servos may strip under
heavy loads resulting in control surface flutter. Screws are
provided in the hardware pack to attach the phenolic arms to the
alloy discs.
As an option you can elect to use alloy arms. The alloy arms
need to be 4.5” for the rear servo and 3” for the front servo. (You
may also wish to use turnbuckles and ball links to connect the 2
servos). Straight arms are preferable, as the pull/pull cables are to
be installed straight and not crossed. Crossing the cable will result
in the cables hitting the rear most former.
Assemble the rudder tray from the wooden components. Glue 4
pieces of scrap ply under the servo mounting screw location. If
you have elected to mount the servos in the standard (rear)
location you can fit the former to the tray at this time. Lightly sand
the area in the fuselage where the tray will be attached. Before
you epoxy the tray in place make sure that it is centred in the
fuselage. You can use CA and kicker in a couple of spots to hold
in position while the epoxy cures.
