Or a basic "how I build the things"
Paint the internal parts of the cockpit area. With most kits this is difficult to see when the plane is finished so I use dark brown, unless the cockpit has detail..like for example in the Roden kits.
Check for fit and then Glue the two halves of the fusealage together.
I add the engine cowling at this stage. Paint any engine parts that will later be inacessable, these will become apparent when you prefit the cowling.
I know that the prop can be added so that it spins (held behind the cowling by a little plastic cap) but to be honest, IMHO, that´s a pointless excercise. The thing aint going to fly so the prop doesn´t have to spin
Also if it´s added now it´s just one part that gets in the way later in the build. I advise adding it near the end of the build.
When glued, fill any gaps (liquifeid sprue is good for this) and file/cut down any excess parts of sprue you may have missed.
Work out a rigging plan. This one´s quite a simple rig but every type of plane needs a slightly different plan /order in which the rigging is carried out. Don´t go mad and try out a complex rig right at the start..it will only put you off.
A couple of Stringbags that are "easy" to rig;
Sopwith (camel and pup)
Albatross DIII
Fokker E.III
Siemens Schuckert DIII
Spad XIII
Drill the holes for the rigging. At this point the bottom wing isn´t attached but just held in place to work out at which point the rigging holes nearest to the wing stub will go. These need to be as small as possible and equally spaced. Note: on this plane I´ll be added the aileron lines and these have to be lined up on top and bottom wings.
Glue the bottom wing to the fusealage...leave off the the tailplane..it is another part that gets in the way at this point.
