My torque tube drive gear assembly seems to have a lot of vertical play. I would guess it is almost a millimeter.

Anyone else notice this on their heli? Is this normal?

Something is wrong. I just checked 2 of my pros and neither have up and down movement like in your video.

No that is not normal. You should remove the tail boom mount and inspect the front drive gear.

I took it apart and it is still not clear what the problem is.

The gear assembly looks okay. I can remove the play by inserting a thin washer between the top gear and the bearing. Maybe I'll live with that for the time being.

If some part is moving on the shaft, what's to stop it even if you add the shim? Either the plastic boom mount has an issue or one of those gears may be moving on the shaft. I would just buy a new front drive gear and check for play. You probably will need one of those in the future if you crash, so no money lost if it's okay.
