Just by coincidence, I've been doing some sorting out this weekend and came across my old Atom. Mine unfortunately has a broken flybar after its last ill fated flight. As you you've probably also discovered Heliguy no longer sell helis, and no spares. A bit of Googling led me to this thread. I've been doing a bit of digging, and got lucky after searching heli flybar on ebay and came across a flybar which looks the same as the Atom. Following a bit of googling, it seems the Atom is also known as a JP Mini Twister. Whether thats the only other name I don't know, but it may be worth a mooch about and try to find the bit you need. It's too late now, but tomorrow after work I will check to see if the flaybar is the same as mine, if it is I'll get one ordered. Similar to yourself, it would be nice if I could get it flying to show my 4yr old boy. Good luck with the search.
ETA I got it a bit wrong, its other name seems to be Twister Mini Sport.
