Hi Marek sounds quite an adventure,
I have just finished reading a book by a British flexwing microlight pilot...Dave Sykes....he made the flight from the UK to Australia in 2011...going through most of the countries you mention...he was badly delayed by weather amongst other things,
His web site is
Solo Flight Global
His book is well worth reading and I'm sure if you contact him he would be happy to give advice of his problems in counties you maybe crossing that he had experience with.
His flight was all the more amazing when you consider he cannot walk and took his wheelchair with him.
Nick.
