Metallic rattling sound?

[PsiLo]

I have noticed that my 600n has a kinda metallic rattling sound which is more noticeable when left side on (the side with the pipe on it). A while ago when I put it in quite hard the pipe got a little bent and I am wondering whether this could be the source of the sound?!

Anyway, here is a video of the last flight out with it and you can notice the sound a little when the heli is left side on to the camera. Around 7:15-7:20 you notice it a bit. Anyone have any suggestions as to what it may be?

It's a TT53 with TT Hiflow pipe.

Could of cracked the pipe i suppose even if you cant see it, or could be the bearings picking up on a high spot.

Other than that mate not a clue, Was that lankey i could hear?

We had a guy up the field have a redline rear bearing fail and it made a really high pitch squeal, When we stripped it down the bearing had locked up and the crank was spinning inside the bearing causing the noise.

I for one wouldn't be flying mine if it sounded like that. Does sound like the rear bearing though
