I'm guessing your talking kits ?? for what engine ? flapped or non ?
Non flapped, Brodak Viking & Vampire are pretty straight forward
Flapped, The Brodak Accentor was one of my first full fuselage builds and was pretty easy with the step by step dirrections supplied
Scratch build a Tornado by Allen Brickhaus (A sig Twister with full fuselage) plans from flying models (I have a set) if needed.
There's all kinds of them.
