I have seen a lot of comments on the web that SMER kits are low tech and poor quality. IMHO this is an over reaction. Almost finished a SMER Avia BH-11 and it is an easy kit to work with. Some small fiddly parts and very soft plastic are the only drawbacks noted. Not a lot of detail but hey, it only cost 4.83 Euros plus about
2.25 Euros shipping as part of a larger order. A much better kit than some I have been inflicted with.Tony Chch NZ
