I have a power kite here, it is a flexifoil 4.9 meter. Im not sure which model/year it is, but its blue with silver/grey
I cant remember what the length of the lines are of hand, but i can measure if needed.
I bought it off ebay about 2 years ago and have used it a total of about 10 times, this is a very powerful kite so its not for the faint hearted. It has dragged me up many a field. It has also lifted me up to around 20 ft in a good wind which was bloody scary.
I can get pics if required but i live in a terraced house at the moment so its a bit of a pain in the arse to get out and pack away again indoors without taking it to my local park. It comes with the flexifoil back pack, and string tidy but i never use it as i found it always gets tangled using it.
I would be looking in the region of around £150 to £200 for it.
let me know what you think and if you want any more info.
