PREPARATIONS

❏ 

1. If you have not done so already, remove the major parts 

of the kit from the box and inspect for damage. If any parts are 
damaged or missing, contact Product Support at the address or 
telephone number listed in the “Kit Inspection” section on page 5.

❏ 

2. Use a covering iron with a covering sock on high heat 

to tighten the covering if necessary. Do this for all of the 
components of the model. Apply pressure over sheeted areas 
to 

thoroughly 

bond the covering to the wood. 

ASSEMBLE THE WING

Note:

 Throughout this instruction manual you will be instructed 

to use screws to secure different parts. In all cases, whenever 
a screw is threaded into wood sheeting or wood blocks we 
recommend that you install the screw and then remove it. 

Apply a drop of thin CA glue into the hole to harden the threads. 
After the glue has hardened, re-install the screw. Following this 

step will insure that you have a solid thread for your screws.

Begin with your left 

wing panel

 first so your assembly 

matches the photos in the manual.

❏ ❏ 

1. Install the grommets and eyelets into the servo and 

then attach a 20" [500mm] servo extension to your aileron 
servo. Secure it with heat shrink tubing, tape or other method 
for securing them together.

❏ ❏ 

2. Install a 8" [200mm] servo extension to your flap 

servo. Secure it with heat shrink tubing, tape or other method 
for securing them together.

❏ ❏ 

3. Remove the tape 

holding the 

servo covers 

to the bottom of the wing. 
Locate two 5/16" x 3/4" 
x 3/4" [8mm x 19mm x 

19mm] hardwood blocks. 

Place your servo on the 
cover, centering the servo 
arm in the slot. Adjust the 

positioning of the blocks for 

your brand of servo.

❏ ❏ 

4. Glue the blocks to the servo cover. Once the glue 

has cured, drill a 1/16" [1.6mm] hole through the cover and 
into the servo mounting blocks Secure the block to the cover 
with a #2 x 3/8" [#2 x 9.5mm] wood screw. Do this for both of 
the servo covers.

❏ ❏ 

5. If you haven’t already, center the servos and install 

the servo arm onto your servos. The servos require a 3/4" 
[19mm] servo arm (typically the longest servo arm with your 
servo). Place your servo onto the mounting blocks. Drill a 

1/16" [1.6mm] hole through the servo mounting tabs into the 

mounting blocks. Secure the servos to the mounting blocks 
with the screws that came with your servos.

❏ ❏ 

6. Inside the aileron and flap servo compartment you 

will find a string. Tie the string to the servo lead. The other 
end of the string is taped to the root wing of the rib. Pull the 
leads through the wing.
