Installing the receiver switch
50. Form the switch operating arm from
one of the discarded pieces of wire
pushrod. Bend a 90 degree bend of
approximately 8mm length on one end of
the wire. Check the fit of the wire in the
hole in the switch and if necessary open
out the hole to suit.
50.1 Bending the first bend of the switch
operating wire
50.2 Open out the hole in the switch to
suit the wire
51. Place the backing plate of the switch
over the remaining rectangular hole in the
servo tray and use it to drill two, 2mm
holes for the switch mounting. Pass the
switch from the underneath into the tray
hole, add the backing plate and secure in
place with the two screws supplied.
Drill a suitable hole for the operating arm
wire in the fuselage side in line with the
switch side.
52. On the other end of the wire make a 45
degree bend, facing towards the rear of the
model, to form a grip. Pass the wire
through the fuselage side and thread the 90
degree bend into the hole in the switch.
The wire is prevented from becoming
detached by gluing a repair piece of wood
onto the tray, allowing it to rest against the
wire. Ensure the switch operates
smoothly and that it follows convention by
arranging the operating arm to push for 'on'
