This has been a quick build so far, the little Heller Me-163 Komet in 1/72 scale. First tooled in 1977 it comes with the little Scheuch-Schlepper tractor too. Not hugely detailed but it looks cool with a bit of detailing. It might make an interesting diorama. The Komet could do about 515 kts or 955 kph with its rocket motor but a range of only 19nm or 35km.
