Just download the manuals for other similiar planes, ( Hint: Tower, Horizon ) and study those.

Your should really not start with a Nitroplanes ARF as your first one.

There will be a few things you will encounter that you will not know how to deal with.

If you've put together other ARF's before these will be trivial points, but for a novice it will be a big deal.

Find someone with experience building ARFs ( preferably with 2-5 under their belt ) and ask them to guide you through the build.
