So, yeah, the Kite configuration means that there is an opposition to one of the points on the Grand Trine. Then, usually, it happens that there are little sextiles going to that point of opposition. It will very obviously look like a kite in your chart if you've got one. The opposition will make the Grand Trine more dynamic...if there's a little challenge in there it usually makes the Grand Trine have a focus....makes it very useful.
