That was all my plan this morning, but every time the kite got about half way up, the kite would start to veer to one side (to the right mostly). A couple of times I made it all the way up to the wind window, then the kite would have a mind of its own and off it would go.
I've been talking in the chat room between reading all the replies here and have learned that I may have been flying using too much of the top lines. Now I know better than that, and know that I should be steering with the brakes, but with having flying only dualies up to now I may have been instinctively flying with the top lines only for the most part. As is known with a dualie, the only balance you need to know is to pull the lines equally. With a quad, you need to do that as well, but you also need to learn to fly equally with the bottom lines as well.
Don't go half way up - stop short of it and hold as long as you can, then back down, Try not to let the kite dictate to you, but you to the kite! Gradually increase the height as you successfully control a lower one!
