Fouga indeed never had ejection seats (except one prototype). their were also larger tiptanks available, but these were fibreglass or something. I would NOT use them as I know of at least one accident where one broke off, hit the tail and killed both crewmembers. Normal aluminium tiptanks are the best, but aerobatics are prohibited with full tanks. ALWAYS make sure tiptanks are empty before doing some aerobatics (use your vide-vite switches). that said, the Fouga is an amazing aircraft. Flies like a dream and you'll have much fun with it. Fuel consumption is a little high. If I remember correct, with the older marboré engines you can fly about 1.5 hours. Don't quote me on that though.
