Ha, My first quad was a Backtracker too. Oh man how I struggled with that thing, two full years before I knew you could even ADJUST it!
I still fly mine occasionally, now I can do a bunch of tricks, including throw and catch on it
My final exam of Quads for a PhD was a 6-pck stack of baby revs, bumblebees on speed, 36 inch leading edge (built by Dugard). Needs big wind (25 or 30mph to generate any flight) but are super fun when the coast guard won't go out of the harbor due to Hurricane forces.
I have heard back from Polo and John you are correct about there being issues !
I will not go into details as to what is happening but I will say that you will be able to place orders in the future, I do not have a time schedule, just be patient and keep an eye on the web site.
