Two 4.8-volt receiver packs are wired to provide
9. 6 volts for the system.
The two receiver packs are taped together with
electrical tape and attached to the bottom of
the transmitter with servo tape.
The compound escapement emulator (center) is
attached to the balsa block with servo screws.
Wiring is quite simple using servo leads
that plug into the emulator board.
Power for the DHT module and the
single-channel encoder is supplied by
two four-cell NiCd battery packs. The
two packs are wired to provide 9. 6 volts.
I tried to use a 9.6-volt transmitter pack
I had on hand, but it would not fit into
the case. The battery pack is mounted in
the transmitter using servo tape, as can
be seen in the photo.
Phil Green’s encoder provides
compound escapement action and a
third position for up-elevator if you
are so inclined to put an elevator on a
single-channel airplane. It also provides
a “quick-blip” feature for three-position
throttle control. The mid-throttle
position is programmable in order to
match your particular engine throttle
and personal preference.
