Futaba PCM 8SGA and 8SGH
It is the start of a new year, and a chance for new
technology and events to change the course of model
aviation. No one knows what is going to happen, but
exciting things are surely on the way.
Thirty years ago, in the November 1984 Model
Aviation, Futaba predicted that its new pulse code
modulation (PCM) system was the wave of the future.
The PCM system contained a microprocessor that
converted and sent the radio signals as binary code.
The instruction manual boasts that the Futaba
Receiver FP-R118GP “is the first R/C receiver in
the world to use the newest computer technology.” This
allowed for many features including reduced noise and
interference, failsafe battery controls, a servo-hold function,
and programmable memory for the best performance.
The museum’s collection contains both the aircraft and
helicopter versions. The aircraft version was donated by Jack
Frost in honor of Wayne Krenz. The helicopter version, of
which we have the transmitter, receiver, tachometer sensor,
and original packaging, was donated by R.F. Sholes.
What will be the wave of the future in 2015? We don’t
have to wait much longer to find out.
