I am currently building an ICP Savannah S.
The main problem is the construction manual. It was originally written in Italian and then (so it seems) the text was put into Google Translate or similar. As a result, the instructions in English are not good and leads to quite a bit of head scratching. Thankfully, there are some good build threads with valuable photos and a better interpretation than ICP's attempt at English. Mark Kyle and iBob's threads are really useful.
Despite the not so great manual, the design is great and the rivet holes fit together well. I am enjoying the build and look forward to the day it will be complete.
