The Revolution kites are actually quite easy to setup, so long as you make sure everything is correctly assembled before launching. The only difficult part is that of the leading edge - I found that this took practice (and one damaged spar) before I got this right.
If you are finding it hard to assemble the leading edge spars whilst they are inside the leading edge, then you can do the following:
The advantage of this is that you can see what you are doing, rather than relying in touch and the 'look' of things. Of course the disadvantage is that you need quite a lot of space to actually insert the complete spar into the kite. Oh yes, and more spars to leave on the flying field if you are not careful......
I used to do this at the beginning (shortly after damaging the spars) but fairly quickly stopped as it took longer to assemble. I now simply double check the Leading Edge spars are correctly assembled by feeling the Dacron around where the Leading Edge spars join to make sure I can't fee a gap there.
