Logo 500 Crashed

[nb8686]

My Logo 500 crashed last week. Just to share the information about the crash.
The cause of the crash was the clamp ring came loose. I thought I tightened the screw with thread lock.
But somehow it happened. The damaged parts are tail push rod, one tail blade holder, tail boom, main gear,
and of course the main blades.

After I changed the damaged parts, I made triple sure I tightened the screw in the clamp ring with blue thread lock.
I also made sure there is no play between the clamp ring and the top bearing.
In addition, I added a little drop of the green thread lock between the clamp ring and the main shaft.

Make sure you do not over tighten it too. I broke the screw head before. You can find alternatives from other heli brands that uses grub screws.


Thanks!

Red one, on the small screw? Not sure this is the right thing to do. Or between the clamp ring and main shaft?
