I picked up this little item from a yard sale. I brought it home and put it on a shelf for the last 2 or 3 years. I'm not sure what model it is and that's what I'm trying to find out. I can tell you that at the moment it needs an upper? mixer arm. Without knowing what the model is to
be precise, I don't know which item I should order. I was able to copy photos of the nearest style of mixing arm and find upper and lower frames that are as close exact as possible to what I have.

The head stopper is identical to that of the 450XL as well as what appears to be the case with the SF mixing lever or mixing arm, depending on which site you browse. I'm getting the impression that whichever site you search, the items are all the same and pretty darned close to interchangeable. The arm may be identical, with the author of the manual setting each identical arm as .5mm variance. However, the frame is not that of a XL heli. So I have a frame saying it is this model and parts diagrams saying it is a different model. Have I confused you yet?

Should I just give up my search and decide to purchase a new main rotor head assy. and hope it will fit the main shaft or do I buy a whole bunch of mixing arms and hope I get lucky? I just don't want to spend a ton of cash and find out I've got something obsolete.

I guess the best thing to do for now is to ask for your help and give me an idea of what model 450 I have here.

By looking at the head and Head Stopper, it shows it should belong to a 450XL. The frame doesn't match that of the 450XL and this is where I get confused. The swashplate is blue and the head is black. I was told this was a RTF model.

That looks an awful lot like a TREX 450SA frame to me. If that's what it is then head parts for the 450SA or SE should work.

Holy Moly, I think you're right! I didn't even know this model existed after all the searches I did for anything close to this style of heli. I was able to locate and download a manual for this model. It pretty much lists the part sizes, but not all, and not the particular part I'm looking for. I can mix and match in resarching part sizes by comparing both manuals if need be.

Tie me to the Tree Of Woe, I guess it's also time to invest in a good micrometer.

This certainly made my day!
