Art,

Without the radio signal from the transmitter, the receiver will
respond to noise and move the control servos to unpredictable
positions, pretty much always resulting in a crash. Modern PCM
receivers can be programmed to assume pre-set control positions in the
absence of the control signal. This will usually result in a crash.
I have hundreds of hours flying RC model aircraft.

Off the wall question: What's the "butt-kickinest" high end radio these
days? PCM's been around for many years, anyone doing error correction, FEC,
Direct sequence spread spectrum?


Hi Dave,

I've been away from it for a couple of years, moving, work and
other expensive hobbies. The high-end Airtronics, JRs and Futabas are
still the top of the line. They use PCM but no ECC, FEC or SS. The
transmitters are pretty programmable though. No need for a seperate
heli radio, just program the mixing for a heli control system. The
computer allows for memories for different models, each with custom
mixing and end-point adjustment. No more sliding servo trays for
elevon deltas. Just put a servo on each control surface and mix
appropriately. Dual servo ailerons or flaperons, no problem - just
set 'em up in the TX. You can spend a grand easy on a radio these
days.

Funny, I just got a bunch of stuff out of storage last week
(new house - YAY!) and was looking at a couple of planes longingly.
