Trex 450 ball link replacements

Hi all, I have one of the old TRex 450xl's from 2006. I was getting it ready to fly again but noticed a few of the plastic ball links are cracked. I want to replace all of the links for safety but parts are not being made for it any more. Can I substitute the plastic rod ends from the newer TRex's in? I have been out of the loop for a few years so I am not sure what if the size of the ball links are the same. I sure would hate to have to dump perfectly fine bird over $2 in parts.

I don't think they changed the size of the links - but you can check the ball diameter. Current 450's use 4.5mm linkage balls. The Thunder Tiger Mini Titan E325 uses smaller links, but I'm pretty sure yours will be 4.5mm. If you're in the US, Value Hobby is a good source in the absence of a local hobby shop.

Good luck, and get it flying!

I got a set of ball links for the TRex 450 pro. They are about 2mm longer than the original ones but the ball size is the same. I can trim the length down with a dreme with no problem. But if I recall right, one end of the stock linkage is permanently threaded on (I could be confusing it with my Caliber 30 though)
