The Park at the airport has two and the other two are still on display at the McDonalds (Polus and on Kerepesi street).
A couple of examples can be seen at Budaörs airport (along with the only airworthy Li-2 of the world and some Mig-21/23s, Ka-26s etc) well worth a short visit.
Just like the aviation museum at Szolnok.
