Not quite. The kit was the original design. The kit is band on, but the ARF is bolt on. Each per ex-factory. If you buy the ARF, you need to convert to dowel and bands if you want it.

Band on is preferable during ab initio training.

The argument about nylon or metal bolts is academic. I've yet to see a prang - and I've seen more than a 'few' - where nylon wing bolts will sheer before they rip themselves and their mount out of the fuselage, or out of the fractured mounting holes in the wing itself. Nylon is stronger and more elastic than either balsa and liteply. An worthwhile concept poorly executed but successfully reinforced through persuasive marketing.
