 Step 1
Locate the items necessary to install the receiver battery and
receiver in the fuselage.
 Step 2
Remove the canopy hatch from the fuselage by sliding the
hatch pin forward. Lift the hatch from the rear and slide
rearward to remove.
Hint: Place a drop of light oil in the hatch pin from the
inside of the canopy hatch so it will operate smoothly.
 Step 3
Mount the switch to the side of the fuselage using the
hardware provided with the switch. Use a #1 Phillips
screwdriver to tighten the screws.
 Step 4
Use a #1 Phillips screwdriver to thread one of the servo
mounting screws into the holes in the radio tray as shown.
This will cut threads in the plywood for the next step.
 Step 5
Apply 2–3 drops of thin CA in each hole to harden the
threads. This and the previous step prepares the plywood
for the screws so they will have a lower chance of
vibrating loose.
 Step 6
Prepare the rudder and elevator servos by removing the
stock servo horns from the servos using a #1 Phillips
screwdriver. Install the grommets and brass eyelets in the
servos according to the instructions provided with the
servos or your radio system.
Hint: If you are installing a glow engine, prepare a third
servo for use as the throttle servo.
