I'm thinking the axle will work. I too have axled the single progressive stack. First to the left, slight pause, then back to the right. Should have seen Rescue's face I said, "see, theres enough wind to fly it." Then I started flying in reverse and he called me a Weasel. 2008 Lincoln City Fall Kite Festival
I did kinda almost attempt an axle with the double. I personally fly with alot of brake. Especially on stacks that pull that hard. Personal style I guess. John (RescueRev) uses 15" handles when he fly's his stack. I really can't stand the feel of the 15's. I'd like to try my 13" Pro handles. I'm pretty sure that with my handles and my prefered brake setting I'll be able to axle it without a spotter. I have a problem with leverage with the 15's. I started to give it the input for an axle and felt the wind come up just slightly. Just slightly enough that only the 1st 3 kites half axled. the other 3 just kinda flopped. But that one attempt (kinda) told me what needs to happen to axle successfully.
Basically it's like with dual line kites. Smaller kites take smaller quicker inputs. The bigger the kite, the slower more fluid you need to be to get the same result. Make sense? So the Double will take more of a smooth arm movment rather than a quick wrist flick.
Would I have a claim to fame if I can do it and get it on video?
I got $20 that says Dean will axle my double stack. I have also decided to go to 13" handles and I will let everyone know how that works out. I would try to axle my stack but I don't have enough time left on mother earth to untangle that mess
