REMOTE CONTROL SYSTEM
MOTHERBOARD
The motherboard is simply a 10- 10- 1/8-inch piece of ply-
wood on which all of the components for the remote control
system are mounted. The various components consist of the
remote control system’s servos, receiver, and battery pack, along
with ten leaf switches, four barrier strips, and a four-slot fuse
holder. Figure 4-4 shows where each item is placed on the
board. The first items to be mounted are the servos.
Cutouts will have to be made in the board to allow the ser-
vos to sit flush with the board. To do this, first place the servos
evenly spaced on the motherboard and trace around their
bases. Cut out the wood where traced and slip the servos in
place. The servos’ body should have tabs sticking out along its
top edge; these tabs prevent the servo from going all the way
through the board and this is where the servos are screwed to
the board. Most remote control systems come with either plas-
tic wheels and/or star levers that are screwed on the servo’s
