I don't know if this happened to you, but I want to share this with you just to be aware of it.
I usually put a small screw, between the frame and the tail boom, but for one reason I did not do it with my 600.
Well, I was doing some pirouetting a little faster that I usually do them and suddenly the Heli kept pirouetting like crazy and my only reaction was to hit throttle hold and cross my fingers
The heli came down nice and level, the only problem was that it was inverted and I did not wanted to flipped (Scare to lost energy and I am not a good auto person.)
When I picked the heli, we notice that the bell was out of the pulley and I think or the boom move in or the tail case move in.
See pictures.
The belt tension was fine, because a friend and I were comparing that before I flew it.

That bearing that you have you have installed it incorrectly, I am not suprised it came off. The large single bearing is for the rear hole of the tail case.

Here is my mod to make sure it will never come off

Yes it is to sit on back hole as mentioned, none the less sucks, hope you get it up and running again soon our friend.

...Once upon a time there were Nitros, flybars and frequency pins...

Thanks, for the information.
Looking the pictures in the manual it is the way I did it.
Now I noticed that is an old picture (page 6) I had it as it is in the instructions, with the bearing in front of the pulley and not in the top and you added extra bearings and I will do that. You have more experience than me with Logo and I will do as you advised.
Thanks,

Ae

Looks like you got her down with minimal damage. You should be able to just run it in the back position and be OK.

Phil,
You are correct. Just mud in the head, little damage in the canopy and one canopy holder broke.

Mine did that a while back. In my case, it was a bug in the CC governor mode that caused the motor to jump to 100% and throttle back very abruptly.
