have you a chance to grab a picture?

Hexagon shaped kites, also known as Bermudas, are inherently UNstable.....the kite itself is pretty much a flat plane and so it needs tails to by stable by any meaning of the word! Some have fuzzy tails...some have long straight tails....some have multiple tails....
These Windborne Hex kite all have two tails......they have an elastic line as the edging for the skin and that presents it own problems.....i have yet to get these to fly stable.

This hex has a 30' fuzzy tail that loops from the two bottom points....it is very stable as it also has a bow line across the back of the kite...

This is a derivative of a Bermuda - it has 8 points and 4 rods....it has a pair of 45' long cotton tails to keep it stable...

This is another 8 pointed kite....it is NOT flat instead it bows backwards..that helps keep it stable as well as three tails too:
