Thanks for the kind words, no did not make it from plans as such but come across Fleet trikes on the web and sort of looked at all his work and went from there, so owe it all to that Gent! Haven't put many miles on it yet but it works really well, infarct much better than expected.
Still need to add panniers,front light and a flag and possible many other things (the list could be endless).most stuff is readily available except a quality flag and pole? any links would be welcome.
p.s had it on two wheels the other day bit scary but fun.
