RE: Help building first plane
G'day
The best thing you can do is to find a local club, go along, ask some questions and go from there.
If you want to build a plane from bits of balsa then you need a trainer plan at the very least. Or better still a kit with a plan and most of the bits in it. If you just want to fly, there are tons of foamies out there which are suitable. But again, practical help is really what you need.
You will learn a lot quickly and at very little expense if you can find a club and some people who will help you.
The internet is a good way to find out some things, but the things you need to know at this stage are far better explained face to face. Once you get the basics, then this is a good place to hone your knowledge.
Enjoy. It is a great hobby.
