Trike Plus

Has anyone built an outrigger from the plans that Trike Plus Buddy Products sells I would like to build my own since money is a huge problem I heard about Trike Plus plans and was wondering if it was worth it to buy them or just do my own thing. I also like the Montegem das rodas on you tube however I believe the guy is talking in Italian and so I don't understand what he is saying. It looks pretty simple just a few bolts and its on. I just don't know what type axles and how to build them so they can be adjustable for the castor and camber as well as how to preload or should I use shocks.

Any ideas

Thanks Fred
