FUEL TANK INSTALLATION (3 Steps)

RUDDER CABLES

ELEVATOR PUSHROD GUIDE

A word here about rudder actuation. The EXTRA uses a
“pull/pull” system. The rudder servo must be located as shown
on the plans to insure the correct cable alignment with the cable
exits. This is not a problem if the die cut servo tray (D/C SHEET
5519, supplied in this kit) is used. Solder the threaded coupler
to the cables, being careful to keep both assembly lengths equal.
With the servo in the neutral position, trim tab centered, attach
the cables to the control horn and to the servo arm. Adjust the
snap-links until the rudder is perfectly straight. A ball bearing
servo is recommended for the rudder control.

You will note that the plans show an elevator support guide glued
to the top of Former “D.” This two-part support is on D/C SHEET
5519 and is to be installed after the servo is connected to the
elevator horns.

After you finish covering the entire model, permanently install
the hinges. The GENERAL INFORMATION BOOK also covers
this.
