I have this kit in my stash along with 2 other Eastern Express kits: the Sikorsky S.XVI and the Nieuport 11 Bebe. I haven't checked any of them against plans yet so can't say how accurate they are, but the mouldings appear to be pretty good. I also had the Eastern Express Bleriot XI which was a total waste of plastic - it was AWFUL!
However, this kit and the Nieuport are Toko (Roden), whereas the Bleriot XI and the S.XVI are not - the S.XVI is also reasonable in mouldings but not as good as the Toko ones, and nowhere near as horrible as the Bleriot! (The Bleriot was so bad I scratchbuilt the whole thing and used maybe 2 kit parts for struts!)
I don't think any other kit I have ever had was as bad as the Bleriot, including other Eastern Express kits....the ex-Roden ones (including the Aviatik (Berg) D.I) appear pretty good, but check plans first!
