What difference does the motive power have with regard to the control
system? A gassie will react the same way as an electric does when
they lose the transmitted control signal, whether by failure or by
going out of range. An AM or FM radio will react unpredictably when
confronted with loss of signal. PCM radios are more immune to
interference and can be pre-set for failure. Or, are you saying that
the method of powering the model makes a difference in what happens
during radio failure? Even if the model is dynamically stable (most
are), if the servos apply full pitch up and full rudder, a spin will
ensue. I have built and flown almost every kind of model aircraft,
rubber, gas and electric using every kind of contol system including
none over the last fifty years. A "back-yard" electric from the
bargain store will crash without control. The model can be built
light enough so that little, if any, damage will be done. Of course,
there is always the chance that the controls will fail in such a
position that a glide to landing will occur. In that case, go right
out and buy a lotto ticket. Some of those "no control" models used a
method using a fuse to burn a rubber band that allowed the empennage
to pitch up. The model would stall and (hopefully) return to earth in
a steep, deep stall. Little or no damage was sustained because of the
lightness of the construction.

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.

The instructions say it can take of and also land on at from hard
surfaces.
With two engines being in the contol positions of either on or off it
would
suggest that without power the plane will "glide" to a landing. this
gliding
after exceeding transmitter range does present distance measurement
problems. Perhaps if the plane was weighted the landing could be more
"precise" as you say
but short of a "crash"
Seems like toys holds interests of every one .

Let's be precise - it will crash...
