Installing The Throttle Control Linkage - Hangar 9 80" CAP 232 Instruction Manual

Section 18: Installing the Throttle Control
Parts Needed
Fuselage
Throttle Linkage (not included)
Tools and Adhesives Needed
Drill
Drill Bit: 1/8"
Step 1. With the engine mounted to the fuselage, mark where
the throttle pushrod will exit the firewall. The linkage to the
carburetor arm should be free of any binding during operation.
Once the throttle pushrod position has been determined and
marked, use a 1/8" drill bit to make the opening in the firewall.
Be sure to remove the fuel tank before drilling.

Step 2. Begin the installation of the throttle linkage by attach-
ing a nylon clevis to the threaded end of a rod (10 turns). Insert
the throttle linkage through the firewall and attach the nylon
clevis to the throttle control arm on the engine.
Step 3. Observe where the throttle control linkage is in relation
to the throttle servo arm inside the fuselage. You will need to
make a Z-bend at the end of the rod and attach it to the throttle
servo arm. Make sure the engine carburetor barrel is in the
1/2 open position and the throttle servo arm is centered. Mark
the location where the throttle linkage passes over the throttle
servo arm. Use Z-bend pliers to make a Z-bend at the mark.
Attach the throttle linkage to the servo arm (you may have to
remove the servo arm to install the arm onto the Z-bend, then
reinstall the servo arm onto the servo). After connecting the
throttle linkage to the servo arm, check again to make sure the
throttle barrel is at the 1/2 open position when the throttle arm
centered and the transmitter stick is at 1/2 throttle. This will
allow for minor adjustments to the carburetor by screwing the
nylon clevis in or out on the threaded rod.
