Not exactly illegal, more a case of unsociable. The wider band receivers will be inclined to respond to anything thansmitting on adjacent channels, the wider band transmitter is likely to cause interference to any receivers on adjacent channels. I have a vague feeling that Futaba were working to the tighter standads before the powers that be mandated the present narrower bands. So the only real problem might well be the actual band of the set - if it is an air only band, no it should not be used for surface.
