 A. If you are installing the lighting kit, make sure
to remove the covering from the tube in the rudder
using a hobby knife and #11 blade.
 2. Use a #1 Phillips screwdriver to thread a 2mm x
8mm self-tapping screw into each of the pre-drilled
holes to cut threads in the surrounding wood. Remove
the screw before moving to the next step.
 3. Apply 2–3 drops of thin CA in each of the holes
to harden the surrounding wood. This will harden
the threads so the screws do not easily strip the
surrounding wood.
 4. Remove the control horn backplate from the
control horn using a hobby knife and #11 blade.
The backplate can be discarded as it is not used in
the assembly of your model.
 5. Install the control horn using two 2mm x 8mm
self-tapping screws and a #1 Phillips screwdriver.
Always use threadlock on metal-to-metal fasteners
to prevent them from vibrating loose.
