450 Autorotation gear slop

[Joseph Orr]

I just noticed there's slop in the auto rotation gear on my Trex 450. It appears the bolt that goes through the main shaft and the main gear is slightly smaller in diameter then the hole in the main shaft.

If I grab the auto rotation gear, the head can be rocked back and forth slightly.

Is this normal?

As long as it doesn't keep spinning, I think it should be fine. Just make sure to inspect it every 5 flights or so and make sure the shaft is not cutting into the bolt.
