lock pushrod connector and position it so that the
forward end protrudes approximately 3/8" [9.5mm]
beyond the connector. Align the nose gear so that
the wheel is pointing straight ahead. With the rudder
in the neutral position, mark where the pushrod
crosses the second inner hole in the remaining
rudder servo arm. Remove the pushrod from the
tube, make a 90° bend at the mark on the pushrod
and cut off the excess pushrod 1/4" [6mm] beyond
the bend. Reinstall the pushrod into the tube and
fit the forward end through the screw-lock pushrod
connector. Attach the pushrod to the servo arm
using a nylon FasLink. Make any fine adjustments
necessary. Then, tighten the SHCS in the screw-lock
pushrod connector against the pushrod.
o 11. Use a plywood pushrod tube support to
secure the steering pushrod tube to the third former.
Glue the outer pushrod tube to the support and glue
the support to the third former as shown.
INSTALL THE POWER SYSTEM
The following sections contain detailed instructions
for mounting an O.S. .61 FX two-stroke glow engine
and the Great Planes RimFire 1.20 (50-65-450kV)
out-runner 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
The installation of a brand of glow engine other
than the O.S. .61 FX should be similar to the
procedure listed below for the O.S. model.
o 1. The fuel tank can be assembled as a two line
system consisting of a vent (pressure) line to the
muffler and a carb line. Filling and emptying of the
tank would need to be done through the carb line, or
an optional fuel fill valve (not included). The tank can
also be assembled as a three line system having a
vent line, carb line, and fill line. If installing a fill line,
puncture the top of the stopper above the sealed off
fuel tube hole. The fill and carb lines should extend
out 1/2" [13mm] beyond the stopper and the vent line
should be bent upwards and left uncut. With the tubes
installed in the stopper, fit the stopper plates loosely
in place with the 3 x 25mm Phillips screw to hold the
assembly together.
o 2. Fit the stopper assembly into the tank with the
vent line pointing toward the top of the tank, but not
touching. The fuel tubing and clunks (fuel pickup) on
the carb and fill lines should almost reach the back
of the tank but not touch. The clunks must be able
to move freely inside the tank when assembled.
