For glow installation apply a bead of RTV
type silicone around the stopper. This will
seal the hole in the firewall as well as
support the front of the tank. Slide the tank
into the firewall and up into the notch cut in
the instrument panel. Using one of the three
supplied tank support sticks, fit it in the
notch at the back of the tank, Apply a drop
of CA to each end and allow the RTV to
cure.
THROTTLE SERVO
The throttle push rod and control linkage
will depend on the engine selected by you. Be
sure it does not bind or control problems
may result.
When fabricating the push rod start with the
engine side. The linkage necessary will
determine where the rod passes through the
firewall. Drill a 3/16-inch hole in the firewall
at the correct location for the push rod outer
casing, ruff the end of the casing with
sandpaper and epoxy in place.
Mount the servo in the tray. Cut the outer
casing and fabricate the inner push rod.
Open the bottom of the sub cowl to allow
engine heat to escape. This opening should
be at least 3-inches wide for a 140-150-size
engine. Open the cowl bulkheads if
necessary to clear the exhaust and any other
engine components.
With the fuel lines attached install the sub
cowl using the four supplied screws. With
the RCS 140, the ignition, Powerflite battery
and switch harness all fit in the top of the
sub cowl. They were wrapped in foam and
held in place by a shelf made from balsa and
light ply. Double check all engine mount
screws for tightness.
