Lee Wakefield's Red Zeppelin

Back in the early 2000's Lee Wakefield in the UK build a coroplast shell around a Trice S that was one of the nicest designs around up to that point. He started developing a kit that was intended to go around a less expensive trike, but abandoned the effort.  There was an extensive set of pictures around that effort, but it seems to have disappeared.
 Here is the original thread from BROL and most of the pictures that went with the post 

Orin Peters - This weeks inspirational coroplast fairing creator

Taking the approach of using a manufactured trike as a chassis and building a fairing around it, Orin Peters has created several velomobiles using coroplast - a readily available and inexpensive material.
He's calling his most recent creation Hidalgo, built around a narrow track  (approx 30" wide) ICE QNT trike, he has done quite well with it, even in races against commercially available machines.  A previous machine consisted of a coroplast fairing around an ICE Sprint.
Here is Orin's website.
Here is a series of pictures of Hidalgo. 
Here is a long thread on Bentrideronline in which he reveals build details.
And here is a Bentrider online thread having to do with some of his racing experiences.
