the sva 9 and 10 were based on the "5" airframe with a second seat added right? want to say the 9 was a trainer and the 10 was and armed 2 a seat version. probably easy for then to keep the older sva 5 sprues and add an extra sprue with the new fuselage and a few knick knacks.
Not quite so, Albatros1234
The fuselage is differnt and the wings as well... if they do not take the easy way, they must rework it completely.
The SVA 5 internacional and the Idro are easier to obtain, but again they have to rework the fuselage and to add bits.
If I do remember right they have the new engine cowl for the international already in the previous SVA.
Anyway the SVAs are good models, at least in the box, much better than the old very old SMER.
