Montague is probably correct. It is very likely an older formula 1 or a Q40 pylon ship. It would be more helpful to know what the span is and how the langing gear was arranged as well as the size engine installed. Q40 and the defunct formula 1 class only offered a resemblence to the full scale and therefore were not always so recognizable.

His suggestion to post the the picture in the general racing or Q40 sub forums would get you an answer.
