Good to hear you are about to be up and running.
just be careful around border areas of some of these countries. Might be worth contacting the appropriate ATC unit, before serving off to get it from the horses mouth, with regards to possible restrictions, closure of airspace etc.
Will you be equipped with HF radio? If so give ATC a call anytime before you go.
Do not, repeat do not fly anywhere near Dams. They are a very strategic target/asset. Consequently they may shoot you down if you arrive unannounced. They shoot first before questioning.
Remember, the military are not always communicationing with ATC and Visa versa. Always pre call the onward ATC if possible.
I am talking from experience at this in Africe, albeit it 40 years ago. Can't see a lot has changed.
Good luck. I wish I was young again!!
