splines facing forward using the mounting hardware included
with the servos. Be sure to harden the servo mounting screw
holes with thin CA.
o 3. Attach a servo arm to each elevator servo with the arm
pointing downward.
o 4. Just as you did with the ailerons, begin assembly of the
elevator pushrods using two .095" x 12" [2.4mm x 305mm]
pushrod wires threaded on one end, two 4-40 clevises, and
two 4-40 nuts. Attach the clevis of each pushrod to the servo
arms and use the pushrod as a guide to position the control
horns onto the underside of the elevators. Secure the control
horns to the elevators with eight #4 x 5/8" [16mm] sheet
metal screws, being sure that you are drilling the screw holes
through the plywood plates in the elevators.
Do not drill all
the way through the elevators! Center the elevators and
use a solder clevis to mark where to cut the pushrod wires.
Cut the wires, solder the clevises to the pushrods, and attach
the pushrods to the elevators, securing the clevises with
silicone clevis retainers.
Note: The Edge 540 1.60 ARF is set up for either forward
(pull-pull system) or aft (pushrod system) rudder servo
positions in order to offset ballast that may be required to
balance the airplane. The rudder servos will be installed
after the power system is put in place. After the installation
of the power system, the current C.G. of the plane can be
checked which will determine the optimum location of the
rudder servos.
The following sections contain detailed instructions
for mounting an O.S. 1.60 FX two-stroke glow engine,
Fuji-Imvac BT-43 EI-2 gasoline engine, and the great
planes RimFire 63-62-250kV outrunner brushless
motor. Each specific installation only contains
information relevant to that particular power system
so you can skip directly to the section that matches
your choice of power systems.
gLOw ENgINE INSTALLATION
Mount the Engine
The installation of a brand of glow engine other than the
O.S. 1.60 FX should be similar to the procedure listed
below for the O.S. model. A mounting template is provided
on page 53 of this manual for installing the included great
planes 1.20-1.80 nylon adjustable engine mount.
o 1. Cut the template out on page 53 for mounting the O.S.
1.60 FX glow engine. Use tape or spray adhesive to hold
the glow engine mount template to the firewall. Align the
vertical and horizontal lines on the template with the lines on
the firewall.
o 2. Use a large T-pin or a wire sharpened on the end to
transfer each bolt hole mark on the template onto the firewall.
