Right, I've been reading the manual for the Waroo and I think the last-post-but-one was entirely my bad.
I suspect I was keeping the bar in the safe zone resulting in no power at all. This is very differnt to my previous kites that all required the bar to be sheeted out completely as they launched.
The Arcs (venom/guerilla) all required aggressive input to get them to turn at any decent rate and they still retained power throughout 100% of the bar throw.
I'll reset the Atom and see how I get on with it.
