some things I have just now picked up on doing my second kit, which is my first "non interlocking" kit is this.

Don't be afraid to sand.
Sand left and right fuselage to match each other because die cutting is not that great

Stack wing ribs and sand them as well because die cutting is not that great..

Be patient, use clamps to trial align everything.

And make for sure everything is aligned correctly before you glue it, when doing a fuse don't count on marking bulkhead locations on each side to align the fuse, actually draw center lines on the bulkheads and align them to a center line drawn on your building board as well..
