 Step 2
Slide the radio tray into the notches in the former. The tray will
fit against the rear of the fuel tank to keep it from moving.
 Step 3
Use a pencil to mark the support block in the fuselage for the
radio tray screw.

Step 4
Remove the radio tray from the fuselage. Use a drill and
3/32-inch (2.5mm) drill bit to drill a hole in the support block
for the screw that will secure the position of the radio tray.
 Step 5
Place 2–3 drops of thin CA in the hole. This will harden the
surrounding wood, making the screw less likely to vibrate loose.

Step 6
Use a hobby knife with a #11 blade to remove the covering
and expose the mounting location for the radio switch.
