I like to put my upright spars where the outer horizontals were, and put those on the back side of the kite upside-down. This configuration always gives me the best control possible. Oh, and don't forget to reverse the polarity of the middle horizontal.
Welcome -- get out and fly. The more you fly, the better you get. The better you get, the more fun you have. The more fun you have, the more kites you get. The more kites you have, the more you fly. The more you fly........the more obsessed you become. Welcome to the darkside.
Learning to fly any quad-line kite can be very difficult if you don't have someone to help you learn. You may have the same problems learning on a Rev, even though it is more forgiving to the beginner. Don't give up on quads in general just because it's hard to learn. When I first started, you would probably look at me and say "He's pathetic". I learned mostly on my own with a home-made quad which would give even a seasoned pro a hard time for a minute, until he got used to its flying characteristics.
Find someone in your area or travel to the nearest kite fests being held throughout the country this summer, (there will probably be two or three within reasonable driving distance), and let the flyers there lend a you hand. Most kite fliers are very friendly and will help you because they want to.
Stick with it. You will soon have a "breakthrough" moment and gain control; then the real fun part of the learning curve begins.
Good luck, good flying, and welcome to the dark side!
Tighten the bungees at the ends of the leading edge, in 1/4" increments at both ends equally, until the leading edge stays stretched. If the leading edge is not centered, tighten the end where it sticks out more until symmetry is achieved. Do this with the verticals removed, adjust, install verticals, fly, repeat until desired result is achieved. This may be done on the field; I tend to make adjustments of any kind on the field so I may check the change immediately.
