as far as building bi-planes goes vlady, just adding a little rigging makes a world of difference.my recommended order of rigged planes is this, fokker Dvii,just needs control lines to elevators,fokker triplane, cabane struts, wheels, ailerons and elevators, albatros, fusalage to struts,tail control, wheels.try them in this order, each one builds up rigging skills ( and making a/m etched brass cockpit interiors!). i have seven ww1 aircraft on display in the front room that go from my early (well, a year and a half ago) attempts, to the albatros seen here, and get a lot of comments from friends and family how smart they look. a word of warning they are very, very addictive!! ive built almost nothing else for the last 2 years!
