The remotely piloted helicopter

Development by Westland of the WISP plan symmetric helicopter (that is to say, one which is sensibly symmetrical about the rotor axis shaft) has advanced to the stage at which four of these aircraft have been constructed for use in a short range surveillance system which is being produced for the Ministry of Defence. It should be emphasised that this particular role of surveillance of the remotely piloted helicopter (RPH) is only one of the many uses envisaged.
