Attached are some pictures of my first trike which I mated
to a bowsprit hang glider wing (Sigma) in 1981. Both the trike and wing were
made by Southdown Sailwings. The red tube on the keel is a parachute.
The trike could fold and went in the back of an estate car (in the
background). I am not sure of the total weight, but it might come within the
nano trike range. Picture shows the trike in the front garden with my two sons
sitting in it. The Sigma had a 12m wing span and 187sq.ft., so it would
thermal quite well. Top speed was 40mph.
