Bent tail shaft
I just noticed that I have a bent tail shaft and am curious if I can buy the shaft without buying the whole tail case? Please help.

Yes, but it will have the belt pulley or bevel gear on it. They used to sell just the shaft. Totally not worth going that route.Heli-itis sufferer.

You sure can! (I think he's talking about the whole tail assembly?)
Align sells the shaft with the gear already on it.
Have you had a chance to look up spare parts?
Which model do you have?

This repair page applies to a metal tail houses EXI 450 but it's the same process as an SEV2 and almost the same as a 450 Sport (less screws)

Look at how much gear mesh/backlash there is before you remove it.
I found when I replaced my friend's tailshaft, the gear mesh was worse. Lots of slop. Don't know if it was the tailshaft difference or what. I ended up adding a 3mm ID .2mm thick tamiya shim

I've had to add a shim on all my TT drive helis(4 of them) after a while.
I put it on the tail case(tail shaft) on the fin side and it takes the slop out of it for good. I guess its a wear thing because they are snug new, and after a while get a bit of play on the tail shaft... either way ez fix, and I'm sure it would work fine without the shim, but to be on the safe side, I shim them when it starts getting play on it
