Section 14-Radio Equipment - QuiQue's Aircraft Yak-54S Assembly Manual

You are now in the final stages in
completing the assembly of your
Yak-54. Quique's method of
mounting the radio receivers in his
proto-type airplanes: Starting with
the plywood mounting plate for the
receiver, motor control servo and the
radio switch:
1. Apply some beads of medium
C/A.
2. Attach a piece of foam the size of
the bottom of the receiver to the
base.
3. Cover the bottom of the receiver
completely with wide masking
tape.
4. Apply more beads of medium C/A
glue to the masking tape and
place the receiver on the top of
the foam.
This system has worked very well for
him for many years. The receiver
floats gently but is not fixed too
firmly. If a receiver is fastened too
tight in the airplane there could be
problems with engine vibration
transmitted to the receiver. See
Figure 62 for an overall view of the
fuel tank; throttle servo, receiver and
switch.

and the push/pull rod outside the
fuse. You may need to make your
own music wire rod to connect the
receiver switch to the outside of the
fuse. You may also need to drill a
hole in the switch button to accept
the music wire. Perhaps your switch
already has the parts necessary to
make the connection outside the
fuse.

Depending on your build, most likely
you will need both receiver and
ignition batteries up front to help
balance your plane. Mount ignition
battery on one side of the firewall
and receiver battery on the other
side of the firewall. See Figure 64.
Ignition module is also mounted on
the side of the firewall, see Figure
65. For ignition switch, cut the fuse
as shown in the picture with xacto
knife and mounted the switch. When
you cut the fuse for switch mounting
make sure you apply a thin layer of
epoxy/alcohol around that area.
Receiver can be mounted in front of
the rudder servo or you can make a
