In my last "crash" the tail blades struck the ground at an angle and one of the blades snapped off. Well it turns out that caused the tail rotor shaft to bend and now I need to replace it. I'm trying to buy a replacement locally so I dont have to wait weeks for it to arrive. The problem is I cant find Align Trex 450 SE V2 tail rotor shafts anywhere, it's like they are no longer sold. However, almost everywhere sells Align Trex 450 Sport tail rotor shafts. Are these compatible with a 450 SE V2 tail assembly? The noticeable difference from the picture is that the sport tail shaft has a hole for attaching the tail rotor hub where as the SE V2 tail shaft has kind of an indent for attaching the tail rotor hub. I don't know anything about the size of them though, such as are they the same length and/or diameter.
Here's the Align 450 Sport tail shaft
Here's an unknown brand 450 SE V2 tail shaft
