my 4.5 razor flies great most of the time, but every so often it acts really unpredictable. as if it is full of sand or the cells arent fully inflated. does anyone else have this issue with the razors?

I had a razor 2.5 and came to the conclusion it was on the verge of being a dangerous kite. Super agile, fast, great upwind, but when the gusts hit watch out. It came close to pulling me out on a number of occasions and I concluded that it was a great coastal kite, but not good for inland conditions. It would also go so far upwind that if you had a wind shift it would turn in on itslef and re-inflate way back in the window unless you were on the brakes fast enough. It would also surge on every gust.

I had assumed that the same applied to all the sizes of the razors, but after talking with several people about this, I have learned that the 2.5 was different animal from the rest of the sizes. I would still assume that the rest of the sizes exhibit similar behaviour, but to a lesser extent.

I agree with Steve... the smaller Razors are definitely smooth wind kites. The larger ones are actually a little more forgiving and in light winds turn a lot faster than most big kites. That said the 3.5 meter has scared the crap outa me on several occasions! The luff; followed by the drift-behind; followed by insta-inflato! Followed by neosporin.

I also have a 5.5 razor it is a beast. Awesome in low winds but frightening as it picks up.

someone had a 2.5 razor for sale, I decided to get a new 2.5 jojo rm+ instead just because I love my 3m so much.

A wise choice for sure. The RM+ is WAY more stable than razor would have been. That's why I like them so much. And as you already know they are no slouch either.

I have a 2.5 / 3.5/ 4.5/5.5 razor love them all. As the wind increases Ijust grap a smaller one to suit the wind condition
