The Valom kits are certainly a mixed bag.
I did some minor scratch built additions to this, but not to the level of the fokker e iii
The main thing was the engine, the kit part was so oversized it would look like a church organ and actually touch the top wing so.
The area of the machine guns and cockpit opening was a mess too.
From what I can see it is Valom's earlier releases that l have some accuracy issues.
In my opinion the Dr1, Hanriot, Pup, Albatros, Fok Dvii all look a bit lacking.
The Nieuport's 11, 17, Spad, Rumpler, Se5a, Fok Eiii, F2b and Camel all look a lot better.
I've now got a few resin kits to expand my choices.
I just snapped up a Brengun Voisin La/Las for a good price...very excited to build a pusher but the rigging looks like hell.
