For a model with next to no rigging you can't go past the Fokker Dr.1, kits available in all scales and a good range of schemes also. The Albatros and Pfalz are both good aircraft to model and are quite standard with their rigging, again available in all scales with good scheme options. If you wanted to go with a monoplane the Morane Saulnier Type N is a very nice little aeroplane, it has a bit of rigging but being a mono it is reasonably easy to do, or the Fokker E.V monoplane, no rigging involved here.
Models like the DH.2 are excellent models but has very complex rigging and not recommended for the novice. There is a huge range of WW1 aircraft kits available in both 1:72 and 1:48 scale, if you are starting from scratch you will have enough to choose from for many many years.
