It fits only on the Axle that comes with it. At this point the only thing I know it's that I must take care with my heli, because I'm not shure to find parts for it!
It was bought from chinese seller on ebay last week. The green PCB on it says HH-009R and 2010/11024. It flys very stable even my 9 years son can handle it with no problem.
Nitropy, As I have suspected, but unwilling to call it just yet, your latest picture and info has confirmed my suspicion. I'm sorry to inform you that you got a fake S107. A real S107 would have a red PCB with S107R5 written on it. As I have said many times before, even a fake flies fine out of the box. The issues are with future support. After parts are broken, people are unable to source components to fix their fake S107, which you have just proven the point. Sometimes these 'small' variants don't seem much at first, until you find out that parts just do not fit. That's why I've been an advocate for people to not buy clones, or return them as soon as you get them.
Anyway, let me get off my soap box, and get on talking about fixing your helicopter. Have you tried putting on just one connect buckle? Was it able to fly with just one? If not, I think the best option going forward is to get a set of genuine connect buckles. You should be able to keep the flybar, blade holder and blades. The distance between the upper and lower blades might be off, but you should be able to get the helicopter up in the air. Does that sound like a plan to you?
I don't quite understand the part where you say it doesn't fit in the axle. Do you mean the replacement shaft is smaller than the original shaft?!? I'm hoping that you don't have to change anything beyond head rotor. Otherwise, if you have to change the shaft, you'd have to change the gear underneath and that could open up a can of worm. So, try again. Loosen the locking screws on the head all the way and see if you could just press the head onto the shaft. Let me know what you find out. I'll try my best to help you get this heli up in the air.
