Hi. I can't assist you in the building phase but perhaps this magazine could offer you something, "World Directory of Leisure Aviation".
Topics covered such as fixed wing/lsa, homebuilts, certified ac, ultralight gliders cert gliders, gyrocopters, trikes...
First time stocked at my local newsagency and they only ordered 2.
I've read through it many times checking out websites and it gave me good ideas on types of trikes I'd like to consider to buy if i went down that road which I hope I do if I move east to Mackay.
Thanks. Chris
