Ah well, you see in France clubs (we don't really have many commercial schools) are allowed to instruct on, and indeed build, home build aircraft. Egletons built their four seat Jodel. Most instructors speak some English but for a conversion you don't need that much common language. I converted to the Wilga and Yak 12 in Poland with an instructor who spoke only polish, which taught me how to make circuit calls in polish, and to order beer....
