Remember Ramraider, you need to treat the rev much more like a soufflé - you can't slap it around like a foil or a delta and expect it to rise into the air - it would just sink.
At the risk of being insulting, one of the common mistakes people new to revs make is to put the upright rods on the front of the kite. The instructions are not always clear on this. They should of course be on the opposite side to the bridle.
I think you just hit the nail on the head took it out earlier same thing would not rise slack lines , so what did i do put the upright rods on the back with a extra knot on the brake line controler and it lifted into the sky not for long as the wind was a bit choppy today plenty of wind then none even some guys with 4m foils were falling out the sky
thanx for the advice guys all was welcome
