This model was an accurate copy of the BK117 helicopter belonging to the London Fire Brigade.  They got rid of the helicopter soon after I completed the model.  Some of the working features included rotating camera, working lights and winch.

It was powered by a Zenoah 23cc petrol engine and weighed around 22 pounds.  Mechanics were by Vario.  The pictures below of the completed model were taken at Sandown Park Symposium in the UK.
