Build The Stab & Elevators; Hinge The Elevators & Rudder - GREAT PLANES Rapture 40 Instruction Manual

6. Make the rudder as shown on the plan from the
remainder of the 1/4" x 2-1/4" x 24" [6.4 x 57 x 610mm]
balsa sheet used to make the fin base. Do not cut the "V" in
the leading edge until instructed to do so.
Set the fin and rudder aside for now.
Build the Stab & Elevators
1. Cut out the stab plan or position the plan so it is over
your flat building board. Cover with Great Planes Plan
Protector or wax paper.
2. The same way you cut the fin base for the fin, use the
stab leading edge brace template on the plan to cut the
stab leading edge brace from the 1/4" x 1-1/2" x 36" [6.4 x
38 x 914mm] balsa stick. Pin the brace to the plan.
3. Finish building the stab from the remainder of the 1/4"
x 1/4" x 36" [6.4 x 6.4 x 914mm] balsa stick and the
remainder of the 1/4" x 2-1/4" x 24" [6.4 x 57 x 610mm]
balsa sheet used to build the fin, an additional 1/4" x 1/4" x
36" [6.4 x 6.4 x 914mm] balsa stick and two more 1/4" x 1/2"
x 36" [6.4 x 13 x 914mm] balsa sticks.
4. Make both elevators from the remainder of the 1/4" x
1-1/2" x 36" [6.4 x 38 x 914mm] balsa sheet used to make
the stab leading edge brace. Do not cut the "V" on the
leading edge until instructed to do so.
Hinge the Elevators & Rudder
NOTES ABOUT CA HINGES
This kit is supplied with CA hinge material consisting of a
3-layer lamination of Mylar and polyester specially made
for hinging model airplanes. When properly installed, this
type of CA hinge provides the best combination of
strength, durability and easy installation. We use these
hinges on all our models, but it is essential to install them
correctly. Follow the hinging instructions in this manual for
the best result. The techniques shown have been
developed to ensure thorough and secure gluing.
1. Use a Great Planes Precision Hinge Marking Tool
(GPMR4005) to mark the centerline all the way down the
leading edge of the rudder. If you don't have a Hinge
Marking Tool, use a fine-point ballpoint pen to mark the
centerline as shown. The pen or the rudder may have to be
raised from the workbench so the line will be on center.
