Bent main bearing block?

[alyon187]

Any body ever seen, heard of one being bent from a minor crash? Ive got a 450 pro dfc that has vibs come and go w no reason behind it. Also when I'm spinning up the heli to test for vibes on the vstabi software I can hear a kind of sputter coming from the motor/main gear area. All my shafts are new w new bearings and blades are balanced. I do have my tail servo cord wrapped around my boom support to take up the slack. Any ideas on vibrations and or the sputtering sound could be? Here's my gear mesh and how my tail is wired.

They can bend, but then you usually notice that the screws don't match up perfectly.

That looks like a metal plate under the fbl. You could try just going with the 3m tape, no plate and no strap, and not bundling the wires close to the fbl.

Ive tested a bunch of different ways of mounting it. Thos way was w the best results. Im not having much issues anymore w vibes, mostly w a nod/vertical tail bounce
