Vertical Stabiliser And Rudder; Rudder Control Horn; Installing The Servo Mounting Frame (*) - GRAUPNER TANGENT FLAMINGO 2006 Bauanleitung

Vertical stabiliser and rudder.

The rudder supplied in the kit is complete and requires only minimal finishing. The hinge is
made by a steel wire running in a factory installed pivot tube installed in the leading edge of
the rudder.
Open-up the rudder push-rod shroud at the rear of the fuselage using an 8-10mm dia. round
file or similar rotary tool.
Using a small round file; form a small semi-circular recess at the top of the fin post to
accommodate the leading edge of the rudder.
Note: Customers building the ARC version may wish to take this opportunity to adjust the
profile of the leading edge of the rudder to match the trailing edge of the fin.
Transfer the position of the two hinge positions in the leading edge of the rudder onto the
trailing edge of the fin post and drill a 3.5mm hole at each point to accommodate the hinge
bolts (eye-bolts) and trial fit with the hinge bolts positioned in the rudder pivot tube. Work
carefully to determine the right depth of the hinge bolts so as to ensure equal and adequate
rudder throws. Once satisfied with the positioning, bond the hinge bolts into place in the fin
post using thickened epoxy.
Tip: It is possible to unscrew the hinge bolt and reset it with a little more adhesive should
you find it necessary to make an adjustment after the hinge bolts have been set into the fin
post.
The rudder is attached by pressing the steel wire down through the pivot tube from the top,
and engaging both hinge points.

Rudder control horn.

Drill a 4mm hole in the base of the rudder to accommodate the eye-bolt which forms the
rudder control horn. The hole to be made such that the hole in the eye bolt is positioned
centrally within the rudder push-rod shroud and at 90° to the rudder itself. Drill carefully,
without piercing the outer skin of the rudder.
Once satisfied, bond the eye-bolt securely into the rudder using thickened epoxy leaving a
small bead of thickened epoxy around the base of the eye-bolt.
Note: Customers building the ARC version may wish to cover the rudder before gluing the
eye-bolt in place.
Customers building the ARF version will need to carefully remove a little of the covering
material around the fixing point.

Installing the servo mounting frame (*)

The wooden parts for both pure glider and the electric version are supplied in the kit – please
select only those parts required.
Note: The servo mounting frame does fit in the fuselage opening! Turn it around carefully
and you will find that it will slip neatly into place. Don't be tempted to sand away too much
material which will result in a poor fit.
